Ray, a realtime raytracing experiment

Downloads:

• ray-src.zip - (185 KB) portable source code (based upon SDL)
• ray-release-win32.zip - (363 KB) win32 executable demo
• ray-early-win32.zip - (102 KB) win32 earlier versions demos

Some features:

Engine:
• 24 bit software rendering engine
• Adaptive recursive quad interpolation to speed-up rendering
• Bitmap fonts rendering.
• Fogging.
• Any kind of linear transform through matrices.

Lights & Shadows:
• Ambient
• Directional
• Omni lights
• Spot lights
• Sharp and soft shadows
• All lights and shadows are dynamic

Materials & colors:
• Diffuse and specular components
• Reflectivity
• Texture mapping / genlock mapping
• Procedural textures (checker, xor, perlin)

Supported primitives:
• Planes
• Triangles (still to improve a lot)
• Boxes
• Quadrics (Sphere, Cone, Cylinder, Hyperboloids...)
• Trilinear cells
• Torus, Tangle, Quartic box

Possible Todos:
• Make refraction work
• CSG
• Port the source to C++
• Work out some kind of parser for human readable scene-files.
• ...a scene editor!
• Triangle-based models (that is: improve the triangle routines)
• Metaballs / volumetric rendering
• Eventually implement some platform-specific optimizations (SSE, 3DNow...)
• too much other things :p...

Some screenshots
All the screenshots were taken on my P4 2,20 GHz running WinXP Home. Click on the thumbnails to see the originals
	Default settings. (Specular, diffuse, shadow, one omni light, one spot light, diffuse light)
	Default settings.
	Texturing enabled (still to improve).
	Texture modulated by Material colors.
	Default settings + soft shadows.
	Default settings + 2 levels of reflections.
	Default settings, shadows disabled.
	Primary rays clipping rectangles shown.
	All settings on (except for modulation and soft shadows).
Screenshots from the early version:
	One of the first rendering tests.
	Procedural animated perlin noise.
	Colorful Xor map, specular highlights and reflections!
