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 final image; see vpGetvpSetImage(3).

The VolPack library must be compiled with the -DDEBUG compiler option for this function to have any effect.
