TracePixel3
Print a trace of the voxels composited into a pixel
Usage
#include <volpack.h>
vpResult
vpTracePixel(vpc, trace_u, trace_v)
-
vpContext *vpc;
-
int trace_u, trace_v;
Arguments
vpc
|
VolPack context from |
|---|---|
trace_u, trace_v
|
Intermediate image coordinates of the pixel to trace. |
Overview
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.
