Lightmaps Part II

Continuing on my lightmap work from the last post, I now have lightmaps working in the iPhone app. I had to fix some texture coordinate issues. In addition I forgot to uncomment out some code when taking the last posts pictures, the lighting only took into account the attenuation and not the surface normals. In addition I had to get multi-texture working in the iPhone engine as well as modifying the shaders.

Lightmaps are applied with a 2x multiplier, which allows the lighting hotspots to actually brighten up the textures, which helps give the surfaces more contrast.

These screenshots were taking directly off the iPhone:

Next I have to add soft shadows and finally implement the radiosity solver.
