Official website (http://zengl.org) is completed now, and as I wrote before in another topic - I prepared wrapper for Magic Particles. You can download it here (http://zengl.org/extra.html). All instruction about compilation are inside. But I want to warn you - this extra demo must be used in pair with ZenGL from svn(because of AV when application close). But you can wait till tomorrow, because I will try to prepare minor release with some fixes.

Another "release" is ZenFont.

For now - no. I don't have this device for testing, and I don't have any plans to buy it or use slow emulators without real hardware... :)

Wow, this is some seriously amazing stuff going on here... ;) I look forward to the first release based on ZenGl. From what I've seen so far - I wouldn't mind it is Command and Conquer Generals looked that nice XD

Heads up, this is what I got for christmas: http://www.archos.com/products/ta/archos_28it/index.html

$100 (usd), 800mhz and I think only 128mb of ram, but it's plenty to be a little dev machine. I'm going to see if I can get this working via debug mode for faster testing later today... But yeah, I don't know if it's wise to try to branch out too much with your project, but if you have the spare cash and time go for it.

Oh nice... I've been looking into those archos tablets. If I buy, it will probably be the 10 inch one. Let me know what your experiences are. Especially concerning pascal gamedev. I know some of us have fiddled with android, but it seems that some extra work needs to be done to make it easier. :)

Did you try this (http://alexmogurenko.com/blog/programming/android-building-free-pascal-compiler-for-android/)?

And merry christmas! ;)

To be honest, I don't think trying to develop for android with pascal is worth the effort yet, but I'm sure I'll fiddle with it in the future.

As for the android device itself, it has some problems. The main issue is the screen; it's hilariously small and it's resistive, so very hard to work with. (The pricier models should list if they're capacitive) I actually ended up installing a third party keyboard similar to swipe to aid in usability. With it, I don't really get that many typos, but I'm still slower at using it than with a qwerty keyboard and stylus (at least for the moment, but dragging a stylus around with you everywhere too isn't too fun). I actually wrote up a nice long post from it to reply to this topic, but I took so long the forum logged me out and lost all progress. The devices also aren't recognized by google, so to get the google market and most of the apps, you have to do some workarounds. Archos has instructions for setting up debug mode, and I'll get around to that tomorrow.

The low memory is also turning out to be a slight problem; while the OS itself allows multitasking, it kills the apps that I wanted to multitask with because it needed more ram to run the active program. It's really no surprise to me, how much multi tasking are you going to do on a device this small? It's not what it's made for ;) Anyway, hopefully the more expensive archos devices will have more ram, but that seems to be a spec that goes unlisted on the product pages. The 28 might only have 64mb, in reality. Very useful though, some apps I have: a few games, irc, vnc, music, video, gallery, skype, email, facebook, chat, opera mini. So yeah, the thing can be useful

ZenGL is amazing! :)

Do you have planned to make it arm compatible? I noticed that trying to compile for arm-linux (under Ubuntu) there is an asm part that stops the compilation; maybe translating these few asm lines in pascal would make it arm-compatible :)

(so it could be also used for maemo/meego)

Andru
07-01-2011, 03:51 PM
ZenGL is amazing!
Thanks :)


I noticed that trying to compile for arm-linux (under Ubuntu) there is an asm part that stops the compilation;
The only function that use ASM-code is m_SinCos, but it must ignore ASM-code and use pure Pascal if CPU architecture is not x86 32-bit... But another problem in the latest version of ZenGL from svn is using object files from original libjpeg8b and zlib(for faster jpeg and png decoding).


(so it could be also used for maemo/meego)
I think this OS's based on Linux will use OpenGL ES instead of OpenGL, so there is a lot of work must be done for ZenGL... :)

If I remember well there is a wrapper from OpenGL to OpenGL ES for maemo, and from what I can remember it works. So developing in OpenGL and compiling for arm-linux should be enough... but I can't be sure :)

I hope next release will be stable 0.2 with frozen API :) I will try to realize joystick support under MacOS X, provide particle editor and maybe start to write documentation in English :)

Sad moment - 64-bit windows binaries now won't work, but 32-bit works fine as always :)

Hi Andru!
Is there any news about ARM support? :)

Then, have you planned something about implementing OpenGL ES on ZenGL (like did the team of Asphyre Sphinx)?

I need to start a 2D project and I would start it with ZenGL (I repeat, it is amazing :D), so if it would be OpenGL ES compatible for when I'll finish the project (less or more) I'll can compile it for win, linux, maemo/meego and ios :D
(OpenGL ES run on also on desktop ATI with latest drivers, I don't know about nvidia)

Let me know :)

Thank you very much!

Andru
01-02-2011, 03:45 PM
Oh, my fault, I forgot about ARM toolchain >_<


Is there any news about ARM support?
I have just build FPC for compilation ARM binaries, and compilation of ZenGL 0.2 RC6 was succeeded, but without support of jpeg, png and ogg(I need to build object files for ARM first). And without MaemoSDK(I'm installing it now) I can't finish linking stage. All operations were made with FreePascal 2.4.2 under ArchLinux x86_64. So, there are no big problems to build ZenGL for ARM architecture.


Then, have you planned something about implementing OpenGL ES on ZenGL (like did the team of Asphyre Sphinx)?
In March I will have a vacation for two weeks, so maybe I will try to do something. Or this would happen sooner, if I become bored by writing documentation and other stuff with high priority... :)

I have installed MaemoSDK (http://img148.imageshack.us/img148/1594/45944382.png)... and it is huge - 2GB! >_< Also seems my Radeon HD 5850 with Catalyst 11.1 supports OpenGL ES using standard libGL.so(I got eglGetProcAdress from it and using this function I got all other OpenGL ES stuff). So, I will think about how will be better to add OpenGL ES implementation to ZenGL and than I will try to do some initialization stuff :) Rendering and so on I will add to TODO-list for ZenGL 0.3.x branch.

The whole ZenGL engine looks really interesting and promising. ;)

I've just looked at the website and I actually didn't see a comprehensive "about" page. There was only a tiny page that summarized the core features/components of ZenGL. Might be something to add, perhaps? :)

Also, will ZenGL be opensourced eventually? (I didn't download it yet, but I have the impression that it's closed). And to what extend is 3D supported? I only saw a lot of 2D components/helpers.

Looking good so far. I will keep a close eye on this. :)

Andru
02-02-2011, 03:40 PM
a comprehensive "about" page
I think "tiny page" is good enough to understand what is ZenGL and what it can. I don't like "about page" with boring description like "ZenGL is the best library for creating your 2D applications ever. With it you can create your own games in such genres like... blablabla", or you meaning something else? :)


And to what extend is 3D supported?
There is only Set3DMode function. I'm not interested in 3D for now. Some very old versions of ZenGL were with simple 3D(models, keyframe and skeleton animation, volume shadows, heightmap, octree, simple shader functions and so on), but all this stuff were dropped.


Also, will ZenGL be opensourced eventually?
ZenGL is OpenSource project under LGPLv3 license.

chronozphere
02-02-2011, 04:15 PM
Well, the about page doesn't have to be a cheesy "We have made the perfect library" kind off page. You can just tell what kind of library it is, What it's goals are (Simplicity, Performance, 3D or 2D, Certain features or whatever), How long it has been around and what games are made with it (history). Also mention that it's opensource, because I missed that. :)

Good to know that it's opensource. I'll have a closer look at it soon.

Andru
02-02-2011, 04:41 PM
Maybe later I will write something like "main goals", but "true" developers looking for real functionality, not for phrases "simplicity, performance, etc." :)


Also mention that it's opensource, because I missed that.
I have started this project on googlecode(svn and downloads are still there), and that's why I forgot to write about OpenSource on official web-page... :)

Small update to ZenGL 0.2 RC6
- [Linux]wnd_SetCaption now is more safely
- fixed problems with camera for different targets(TARGET_SCREEN and TARGET_TEXTURE)
- fixed problems with ini_ReadKeyStr, key_GetText, filet_GetName, file_GetExtension and file_GetDirectory(for ZenGL compiled as library)
- DIRECTORY_APPLICATION and DIRECTORY_HOME now returns PChar for Delphi 2010
- argument Directory was deleted from file_Exists
- text_Draw now won't crash if textures were not loaded
- fixed file_Find
- fixed crash when png cannot be loaded
- fixed loading of png when compiling 64-bit binaries for Windows(PasZLib is in use for this, still looking for correct solution)
- added new function file_Remove

Links was updated here (http://www.pascalgamedevelopment.com/showthread.php?6404-Description). Website is down now, so only googlecode mirror is working. Also I'm preparing update for LightEngine 2D(I think it would be available in 2-3 hours). For this update Vad has implemented soft shadows and made some optimizations :)

update: Sad, but LightEngine 2D will be updated later because of some problems with stability of new code :(

Thats good news!
I was wondering, though. The version number. How come it's 0.2? Does that mean a lot is still in the works? And in terms of a roadmap, what features can we expect to see in the coming updates?

Andru
06-02-2011, 10:27 PM
How come it's 0.2? Does that mean a lot is still in the works?
Not much, I want to release 0.2 with full documentation and additional tool :) So, Roadmap for now is something like this:
- documentation
- ZenParticles for editing emitter files for particle subsystem
- correct solution for Windows x64 problem
- getting resolution list for MacOS X(for now zgl_Get( RESOLUTION_LIST ) will return empty zglTResolutionList)
- joystick support under MacOS X(but this feature maybe will be moved to 0.3.x branch)

Maybe something else will appear and I will work on it :)

Andru
10-02-2011, 07:00 PM
ZenGL 0.2 RC6 Update 2
- [Linux]fixed file_Find(it was fully rewritten)
- [MacOS X]now list of screen resolutions can be gotten
- stages of OpenGL initialization have been refactored and fixed problem under Linux

Links as always are here (http://www.pascalgamedevelopment.com/showthread.php?6404-Description). I have already wrote some draft version of documentation(part of it), so maybe I will show it this weekend :)

Andru
23-02-2011, 01:32 AM
I have made new branches in svn for current stable version: 0.2.x (http://zengl.googlecode.com/svn/tags/0.2.x) and 0.2.x-d3d (http://zengl.googlecode.com/svn/tags/0.2.x-d3d).

changelog:
- [Direct3D]now correct matrices are used
- [Direct3D]implemented auto generation of mipmaps for Direct3D9
- fixed file_GetName, now it will return file name even if it without extension
- added new parameter SizeXYBind to parameters of particle
- pengine2d_Draw now returns BlendMode and ColorMode which were set before
- now rtarget_Add will check GL_MAX_RENDERBUFFER_SIZE before creating frame buffer
- added USE_TRIANGULATION to zgl_config.cfg
- added few SND_FORMAT_* constants for modular structure of sound decoders without depend on Sound API
- added GAPI_CAN_AUTOGEN_MIPMAP for zgl_Get

I'm going to release stable version 0.2 this weekend :) But seems documentation(and also tools) will be available separately.

Andru
27-02-2011, 08:32 PM
ZenGL 0.2 stable has been released :) So, now I will work on ZenParticles and documentation next week. Current two goals for roadmap of ZenGL 0.3.x are:
- OpenGL ES render
- multi-threaded resource loading

All links as always are here (http://www.pascalgamedevelopment.com/showthread.php?6404-Description). And one more - Matthieu GIROUX has written some unit which implements compatibility with Andorra2D and DelphiX classes TSprite and TSpriteEngine... In few days I will check it and maybe release it like extra-unit for ZenGL :)

Andru

This is the first bugfix release in 0.2.x branch, which will be supported till next major stable release :) Also there was started wiki (http://zengl.org/wiki) and ZenGL(0.3.x branch in svn) now can work on Windows Mobile even with OpenGL ES 1.0(thanks to Vad for testing and help)! :)

Changelog:
- [Direct3D]slightly optimized render
- now ZenGL will check for GL_EXT_texture_filter_anisotropic for using anisotropic filtering
- fixed snd_LoadFromMemory
- now closing the application will reset all states and so on

Would you feel inclined to make a youtube tutorial? I have tried to get FPC working on my Macbook but it just became a too frustrating to do anything meaningful - e.g., using opengl or sdl - neither of which i have used in the past

Andru
05-09-2011, 09:38 PM
"Video tutorials" is not mine... and I don't like such tutorials, this is not for true programmers at all :) I will update my wiki this week with new scripts for building fpc(for iOS SDK 4.3) and new steps with screens. Templates used by me with XCode4 I have got from here (http://web.me.com/macpgmr/ObjP/Xcode4/). Very useful articles BTW :)

PS: now I have a bit free time, so I will try to prepare new public version of ZenGL. And iOS support have been tested not only by me, so... new release just waiting when I will beat my laziness :)

WILL
05-09-2011, 11:54 PM
I've also read that readme files isn't for real programmers either, but where are those programmers now? :P

I think Video Tutorials just take advantage of an extra medium. You get to see whats going on in the desktop that you couldn't see unless you were actually there. Anyone have a plane ticket to the Ukraine? :D

Seriously I don't see how it's bad, unless you have a horrible kackle. The Germans seem to pull off a perfectly good video explaining their own projects. Then again it is nice to see visual demos of what your project is doing. Darthman does a great job with this for example. It also gets more people interested in your project, and for that alone it should be worth it.

Just a few tips from a guy who has learned a few things over the past 10 years. ;)

Andru
26-02-2012, 10:29 AM
is it possible to read theora video from memory stream ?
Yes. For any resource there are always file-reading and memory-reading functions in ZenGL. For video it is video_OpenFile and video_OpenMemory. Currently I have no ideas which video to use for standard demo, so... as soon as I got something interesting, I will add demo to svn :)

More the merrier! :)

I'd like to see more than just Hidden Object games on the iPad from ZenGL however. So far the only non-hidden object game I've seen and can recall is Sushi Quest. Dreams of a Geisha would be the third genre from Pascal land put onto the iPad/iPhone. Any other ideas that could be done using ZenGL?

Andru
04-03-2012, 10:10 AM

ZenGL doesn't limit programmers in genres, so it can be anything :)

WILL
04-03-2012, 11:25 AM
Well true, though hidden object games don't really show off the game library's capabilities. Something like a platformer or another kind of action-based game would do better to prove it's effectiveness to make exciting games with it.

Have there been any successful attempts at this level of game performance on real hardware using ZenGL? I'm sure it's possible, but with only point and click games to guage it's performance... why not create a freeware game to promote such use?

...especially if you are selling licences for iOS and Android developers.

Andru
04-03-2012, 12:48 PM
This doesn't depend on me, so :) As for performance moment it doesn't depend on genre of a game, it depends on fillrate, count of different objects on scene and many other details. And Hidden Object games or Match-3(as Dreams of a Geisha) are pretty dynamic sometimes, with a lot of objects and particles on screen. ZenGL is quite fast, but even with it you can always create some poor performance code, there is no magic solution for avoiding this :)

But main answer for "why there is no commercial platformers based on ZenGL" will be - such genre is not popular nowadays for commercial purpose(as a casual game). And considering that Pascal is not so popular and ZenGL popularity is much lower... I think you can make some conclusions :)

Oh, and one thing about action-games. There is one project here (http://www.sigma-team.ru/content/view/39/51/)(this version is unstable and based on old version of ZenGL).

http://zengl.org/projects/asta_screen02s.png (http://zengl.org/projects/asta_screen02.png)

But unfortunately speed of development was decreased a lot because of lack of time(main developer is busy with something else, far from game development), as I know.

But main answer for "why there is no commercial platformers based on ZenGL" will be - such genre is not popular nowadays for commercial purpose(as a casual game). And considering that Pascal is not so popular and ZenGL popularity is much lower... I think you can make some conclusions :)

Hmm... I dunno there are some platformers on iOS that seem to follow in that flavour of casual gaming the way it's interface works. League of Evil 1 (http://itunes.apple.com/ca/app/league-of-evil/id405552598?mt=8) & 2 (http://itunes.apple.com/ca/app/league-of-evil-2/id493832593?mt=8) for example are quite popular and you can take or leave them when and where you want. Levels aren't too big either so it's more of a casual game than a hardcore platformer like how they used to be on the consoles.

However yes, you cannot control who makes what with your game library. It sould be a huge boost though if someone did take full advantage of ZenGL's capabilities and made something exciting with it for mobile hardware. Even Windows or Mac as well too.

Very strange, I don't have such results even on my LG Optimus One with 600Mhz and didn't get any complains from other users. Try to run compiled demos without debugger and so on(do you use Delphi?), and check if there no activity from some antivirus or whatever else can eat system resources on Windows :)

the demo10 (Tiles) has a big exe size ( 675kb) , i compile it with delphi and the size reduce to ~150kb
That is because there is zgl_textures_jpg included(I forgot to remove it) and compilation with FreePascal uses static linking with libjpeg, which is much faster than any other solution. But this can be disabled any time in zgl_config.cfg if you need.

Hey any plans for OUYA support for ZenGL?
Maybe someday I will take a look on it, but this is just an a bit modified Android, so I don't see any problem to run there ZenGL. Support for any special buttons I think can be easily done via improving ZenGL.java :)


And where does support with Oxygene for Java sit, if I may ask?
Unfortunately this is too heavy(because ZenGL is native compiled library) and not interesting, so I won't provide any wrappers for Oxygene.

Keep up the good work! it's fantastic that you've got IOS and Android supported to a usable level but I don't understand why you bothered to support Direct3D, that's a whole lot of work for nothing. PC's you'd just use GL anyway and microsoft are never going to allow a game on any xbox that wasn't written using their API.

Do you support GL 3.2+ across windows, OSX and Linux? if so on OSX, have you had any problems with uniform buffers? They're utterly broken for me, struggled for ages to try and get them working. I'm on a hackintosh so I don't know if it's due to that (even thou my Nvidia card is one that ships with some macs) or if it's just OSX in general. I've found a few references in forums to people having similar issues, but again they might also be on hackintoshes, they don't say, so I can't find a common denominator.

Andru
01-04-2013, 05:24 AM
but I don't understand why you bothered to support Direct3D
Because commercial projects on Windows should use it, if you want to avoid a lot of problems with crappy drivers and stupid users without vendor drivers at all(sometimes they have only standard drivers provided by Windows) :)


Do you support GL 3.2+ across windows, OSX and Linux?
ZenGL is 2D oriented, so I don't use so progressive API.

phibermon
01-04-2013, 10:37 PM
Ahh yes very good point, there's many older devices+drivers that only support Direct3D properly, S3 chips for example.

But the same is now true if you don't use GL 3.2, it's actually the case that GL1 and GL2 legacy functions are increasingly being implemented in the drivers to use the DX11/GL4.x programming pipelines. As a result there's many instances where GL1/2 support is becoming unstable and even some legacy functionality (such as display lists) is not supported directly in hardware. The fixed pipelines in cards have long since gone and are emulated at the driver level. Nvidia tend to be really good with not breaking old things, ATI tend to break somthing in every driver release.

Intels latest line of chips are a good example, dramatically slower smooth line/point rasterization and will switch to software if you try to use line stippling (at least in my tests of 1 1/2 years ago). Any depreciated functionality could potentially suffer the same fate.

Remember they're focusing on game support and games that use GL1.x and GL2.x tend to be a lot less demanding on the card and thus they don't really care about optimizing that much.

So it's not a case of only switching if you need the new functionality, you should concider supporting just for performance/stability concerns with the same justification you rightly use for Direct3D.

Andru

For 2D glBegin/glEnd is faster than glDrawArrays, because of no need in actions with memory for preparing buffer.

If it was bad enough and I had noticed it then he would also have felt the effects of behaving badly on the forums.

If I may make a suggestion; You got scolded for behaving badly and swearing on the forums. Learn from it and move on. I don't organize my day to ruin yours. Statements like the one you just made only serve to make you look immature. And that is the same for everyone.

Всем привет!
На данный момент я главный разработчик ZenGL, по не гласному соглашению с Andru.

Скачать можно на SourceForge (https://sourceforge.net/projects/new-zengl/), текущая версия 0.4.7. Там же находятся последние версии начиная с 0.4.2, до этого выкладывал версии на GitHub (https://github.com/Seenkao/New-ZenGL).

На данный момент не поддерживается iOS и не полностью поддерживается MacOS. Для MacOS не скомпилированы библиотеки под ARM-архитектуру, если у вас Mac M1 или M2 вы можете сами собрать для себя необходимые библиотеки. Для x86_64 архитектуры библиотеки собраны.

По сравнению с прошлыми версиями ZenGL были произведены достаточно не малые изменения:
1. восстановлена возможность сборки под Android используя Android Studio.
2. добавлена полная поддержка OpenGL/OpenGL ES.
3. добавлена библиотека Green Engine (GE), основанная и работающая используя ZenGL, это:
3.1. поле ввода.
3.2. работа с цветом.
3.3. работа с меню (тестовое состояние).
4. добавлены демки для тестирования полного OpenGL/OpenGL ES.

Многие изменения можно узнать на сайте FreePascal (https://forum.lazarus.freepascal.org/index.php/topic,49143.0.html).

Сборка динамических библиотек, на данный момент, отключена из-за множества изменений (честно говоря я об этом изначально и не задумывался), восстановление данной возможности в процессе.

Ведётся документация, но в основном внутри самой библиотеки и в сопутствующих демках. Так же заполняю потихоньку документацию на вики (https://sourceforge.net/p/new-zengl/wiki/Home/).

Изменений было много. Список изменений в файле Update_ZenGL.txt, извиняюсь, но только на Русском языке.

You can download it from SourceForge (https://sourceforge.net/projects/new-zengl/), current version is 0.4.7. The latest versions starting from 0.4.2 are also there, before that I posted versions on GitHub (https://github.com/Seenkao/New-ZenGL).


Currently not supported by iOS and not fully supported by MacOS. For MacOS, libraries are not compiled for the ARM architecture; if you have a Mac M1 or M2, you can compile the necessary libraries for yourself. Libraries have been compiled for x86_64 architecture.


Compared to previous versions of ZenGL, quite a few changes have been made:
1. The ability to build for Android using Android Studio has been restored.
2. added full support for OpenGL/OpenGL ES.
3. Added the Green Engine (GE) library, based and working using ZenGL, this is:
3.1. entry field.
3.2. working with color.
3.3. working with the menu (test state).
4. added demos for testing full OpenGL/OpenGL ES.


Many changes can be found on the FreePascal (https://forum.lazarus.freepascal.org/index.php/topic,49143.0.html) website.


Building dynamic libraries is currently disabled due to many changes (to be honest, I didnÂ’t even think about it at first), restoring this feature is in the process.


Documentation is being maintained, but mainly within the library itself and in accompanying demos. IÂ’m also slowly filling out the documentation on the wiki.


There have been many changes. The list of changes is in the file Update_ZenGL.txt, sorry, but only in Russian.

;)



Хотел создать новую тему... но Andru тут видимо уже не объявится.

I wanted to create a new topic... but Andru apparently won’t show up here anymore.

I have no idea what ZenGL is but it's nice to see some activity in the field of Pascal. Thanks for your efforts.

Не за что. Главное чтоб полезно было людям.

В соседнем топике (https://www.pascalgamedevelopment.com/showthread.php?6404-Description) основная часть расписана, была давно.


Google translate:
My pleasure. The main thing is that it is useful to people.


In the next topic (https://www.pascalgamedevelopment.com/showthread.php?6404-Description) the main part is described, it was a long time ago.
