Research
Here are some of the links we used during our research and process
http://developer.nvidia.com/page/home.html, used for our research on shaders and the various inputs that can be given to a shader
http://developer.download.nvidia.com/opengl/specs/GL_EXT_texture_array.txt, covers the description about the texture arrays feature
We also had to go through a lot of Panda3D's documentation on Exporting to Autodesk Maya and Autodesk Max and it's Shader system. These documents can be found at the online Panda3D Manual through the following links,
