TDC_RCV.pas line 925 - procedure DriveTrainUpdate is strange.
in C code is :


void DriveTrainUpdate(TDriveTrain* pDTrain, float gas, int gear)
{
float fActiveRPM;

Just a short info about dynamics :) I start to cooperate with mathematician
on profesional 3D fluid dynamics software, based on Navier Stokes equations. I'll inform you about it. It is pretty hard...

Very good time results :) my Scene where is 53 objects takes about one minute with antialiasing...
terrible.I have to do something with that speed :) However here is the result :
...

:-) nitrogen, how many seconds do you render the same scene with antialiasing, and without antialiasing ? Let's say the scene 512x384 .

I think it will be hard for me to implement kd-tree , but I...

I implemented full antialiasing support :

yes, I have implemented refraction algorithm, from what I see on the flipcode website, tere is raytracing tutorial...
however, I need to implement transparency to objects...
I think refraction is...

nothing special in my render :-) Just simple test like this :
http://sweb.cz/SOUThavirov/shotx.JPG

It will be looong way until my render will be able to do something like this :-)...

thank you nitrogen again .

to Nitrogen >> Have you solved a sampling(antialiasing) in your raytracer ?

I'm not going to do a game, just would like to do some software renderer.
I know that real-time raytracing is possible. I don't know algorithms for this, but somewhere I've seen real-time...

I got it...finally, thanks to Nitro again. I noticed that I had a bug because I didn't Add vector of previous color and color after raytracing in the reflection block of code :-) thaanx 8) This was...

Thanks Nitrogen. I guess it's based on tutorial that is on flipcode.
Looks very good.

How have you made antialiased result ?? I haven't done antialiasing yet :)

Hi ,

I have done a simple raytracing engine in Delphi,
works well, until I have more than one light and set reflections
on. I think I have problem in steps order...

There is just for Each...

yes exactly, that's the reason why I train-to get out of the keyboard for couple of hours per week.So, keep training:) 8)

I know...Brazilian Jui Jitsu , I never did it, but know it, my friend do this..
and really interesting :) So keep training if you can.It is important to do also something else than only...

muay thai . But I don't have time...so I do bodybuilding for fun.
and you?

Hi, I'm 20 years old,and I'm from Czech Republic, working as a programmer under delphi 2005 and Oracle.I've been programming since 13..in my free time I work on my personal projects.I like body...

yes I mean inverse kinematics, but I'm interested in algorithm, so it would be better for me to see some algorithm..or source code...don't you know any ?
As I see, newton has everything :-)...

of course :) I know glscene , who not :)

btw. and any IK engine, do you know ? I have already found radiosity renderer in delphi but...it's so slow....
really slow algorithm..I would need some...

Yes, I'm interested in precision physics computing...dynamics, simulations etc. If I'll translate that C source of fluid mechanics (under opengl) I'll give you info..but it is hard work..exactly fast...

That newton seems very interesting...

I've already found fluid mechanics source, but in C,
it wouldn't be problem for me to translate, but it uses
fast fourier transformations (fftw) in C, and...

So it is very nice that you add it here for free..if you paid 40 pounds..
I should say thank you, so Thank you .-)

So, newton DLL can be binded into EXE and nobody shouldn't know that it uses DLL...

You paid 40 pounds to translate it from C to Pascal ? Really ?
Who did it, some company or person ?
I know newton engine...but it requires DLL that has to be distributed
with final EXE file...I...

thanks a lot. it works fine now.

btw. very very nice piece of code...and dynamics simulation look
very nice.

btw2. do you think it would be hard to translate 2d algorithm to 3d ??
using...

it can be bad graphics card drivers...it can be enything.
please, specify, when exactly you get that error , and you configuration (hw,sw)...
