Raytracer with source

[paulrobello]

This is an ongoing project I have been working on in my free time for a few months. It has a full scene scripting language, anti aliasing and is easy to add new object types by deriving them from a base class. All the texturing in the picture was done with procedural textureing and layering. It supports reflection, refraction, shadows, texturemaping both image and procedural. it supports plane,box,sphere,cone and a few other primitives. It is by no means complete or bug free.

It was realy fun to make hope you enjoy it.

You program crashes on non-english country settings. In e.g. Germany I'
ve 0,0 instead of 0.0 for numbers and . is used as thousands separator.

Please make sure the correct handling for , and . is used. It's frustrating to see 50 Exceptions upon starting you demo picture.

The old Delphi separator feature, set it in Control Panel or add a line at the begining of the project specifying the separator

Well, why don't you simply hardcode these settings if you insist in your program on using them? Could really save some trouble ;-)

Well, but I found some other problems while testing and some suggestions for improvement:

1. When closing the program using the X of the window while your program is rendering you program crashes with an AV.

2. If defining a object with a material not defined before your program crashes leaving the buttons disabled (missing Try Finally Block) requiring to restart the program to continue rendering

3. It would be nice to have a small wizard to define new materials and basic objects

4. Little window in the code window with non-reflection preview showing how it could like.

5. Zomm in\out function

6. Alphablending with high alpha values sometimes looks a bit pixelated if FsAA is not enabled.

That's for now. Great work anyway!
