typedef struct { float radius; float height; int nverts; int nchips; int endcap; MAV_surfaceParams *sp; MAV_matrix matrix; void *userdef; } MAV_hellipse;
When rendered, nverts vertices are used to facet the curved surface of the half ellipse around the Z axis, and nchips vertices around the X axis from 0 to 90 degrees. Both values are only applicable if they are greater than two and mav_opt_curveLOD is not set. The symbolic constant endcap, set to MAV_TRUE or MAV_FALSE, control whether or not the object has an endface or is effectively hollow.
