I created a Python script that generates Radiance parallel views of each quad in a RAD file. It also generates an OBJ and MTL file such that once the parallel views have been rendered, they are already mapped to their quad in the OBJ file. This amounts to a model with view point independent textures on each quad.
The script most definitely has some bugs, but it has worked well for my research. I hope it can be a helpful starting point for anyone else trying to use Radiance to generate view point independent (i.e. non-specular) textures of a scene via parallel projections.
