Update Time

In my quest to get shaders working I have learned a few things. I am almost 100% happy with the system now. There are a few issues to resolve before I move onto something else. A number of major changes have taken place during the past few weeks.

• I have re-written the material format. It is back to XML and supports diffuse color, normal mapping, specular highlights, glow and falloff highlights.
• A number of pre-defined variables are provided to the shader programmer providing an interface between the engine and GLSL.
• Tangent-space is calculated for each model when it is loaded and is stored in the data structure.

Issues to resolve:

• Multi-light rendering
• Multi-pass rendering for special effects
• Absence of some textures isn’t functioning as it should.
