NAME

IntrSrfRayPreprocessSrf()  

SYNOPSIS

user_lib/srfray.c:59

VoidPtr IntrSrfRayPreprocessSrf(CagdSrfStruct *Srf, int FineNess)
 

DESCRIPTION

Preprocess a surface for fast computation of ray-surface intersection. Returns NULL if fails, otherwise a pointer to preprocessed data structure. The preprocessed data is in fact a hierarchy of bounding boxes extracted while the surface is being polygonized.  

PARAMETERS:

Srf: To preprocess.

FineNess: Control on accuracy, the higher the finer. The surface will be subdivided into approximately FineNess regions in each of the two parametric directions.  

FUNCTION RETURN VALUE

VoidPtr: A handle on the preprocessed data, NULL otherwise.
