[Soc-2007-dev] Status Report

[Miguel Torres Lima]

Hi,

I add already created an inefficient version where was done for a material:
- All light parameter calculations for lamp, sun and hemi lights
- All specular and diffuse shader calculations
- VColLight, VColPaint, Shadeless and TexFace options
- Ambient color
- Simple texturing example with using current uv coordinates and adding the
colors

You can see most of it here

What I've done this week was to rewrite part of the code,

+ parallel light and material structures
+ hash table to assign a GLSL Material to each blender material
+ create structures only for visible materials and delete and/or create new
ones at every scene or layer change
+ created glsl program structures
+ removed all the if statements from the glsl specular and diffuse shader
calculations, except from minnaert and blinn, to avoid branching on old
graphics cards
+ glsl function for fragment visibility calculation for all light types
except spot lights
+ currently trying to generate the fragment shader's main function on the
fly

Next week I hope to have all the features available in the earlier version
implemented and to start working on textures for materials.
