/**
 * objectset.h - blue-steel ObjectSet structure
 * @author Brian Sweatt
 * 
 * Contains the ObjectSet structure for holding pointers into arrays of Triangles, Spheres, 
 * materials, and lights that together represent a scene.
 * 
 * The num_ fields in an ObjectSet must directly correspond to the number 
 * of objects for each type. It is possible to define values that are less than the actual 
 * numbers for these fields, and the SPU will only DMA in the front of the array up to
 * the given values. Larger values than the actual numbers for the arrays should never be 
 * provided as this will result in undesirable data being DMA'd over each frame.
