The obj3d package manages lists of 3D object files to present, with shuffled order and train / test sets.
It looks for Wavefront .obj files in subdirectories organized by category names -- these .obj files can be loaded into a gi3d / eve scene for rendering.
This example is useful for seeing how to generate lists of directories and files.
CU3D_100_plus_models_obj.tar.gz is a set of 100 3D object categories, with 14.45 average different instances per category, used for much of our object recognition work, including the above paper and originally: O'Reilly, R.C., Wyatte, D., Herd, S., Mingus, B. & Jilk, D.J.
