vpTracePixel(3) Library Functions Manual vpTracePixel(3) NAME vpTracePixel - print a trace of the voxels composited into a pixel SYNOPSIS #include <volpack.h> vpResult vpTracePixel(vpc, trace_u, trace_v) vpContext *vpc; int trace_u, trace_v; ARGUMENTS vpc VolPack context from vpCreateContext. trace_u, trace_v Intermediate image coordinates of the pixel to trace. DESCRIPTION This routine is for debugging the rendering algorithms. If (trace_u, trace_v) is a valid set of coordinates in the intermediate image then a printout appears during rendering showing a trace of all of the voxels that contribute to the pixel. The intermediate image is not the same as the fi- nal image; see vpGetvpSetImage(3). The VolPack library must be compiled with the -DDEBUG compiler option for this function to have any effect.
