Constructor & Destructor Documentation

const GA_PrimitiveGroup prim_grp = 0,
fpreal  relative_padding = SYS_FTOLERANCE_D,
fpreal  absolute_padding = 0 
)
explicit

Construct an RTree of primiotives in the given group. padding is relative to the bounding box radius of each box in the rtree to ensure there is always enough precision to represent a non-zero padding even for large models
