OBJ

Wavefront .obj is text format for simple 3D geometry. It can contain vertex, UV position, vertex normals and faces made from these. Faces can be assigned to named objects and groups. As most OBJ writers/readers only support absolute indices it is not possible to merge two OBJ files by copying one into another. For that tools need to be used that rewrite the absolute indices.
