Detailed Description

This class represents the attributes of an OBJ render group.

OBJ models are broken up into multiple groups for rendering. A group corresponds to a single draw call to the graphics pipeline. Therefore, we need a new group whenever we have a new material. In addition, OBJ files can explicitly create new groups with the "g" or "s" command. We also create new groups with an "o" command, though that is not standard.

touched

bool cugl::scene3::GroupInfo::touched

Whether this info has received any vertex information (for parsing)

vertCache

std::unordered_map<VertexInfo,GLuint,VertexHasher> cugl::scene3::GroupInfo::vertCache

A vertex cache to eliminate redundancy

vertices
