NAME


vpSetDebug - enable/disable debugging options

SYNOPSIS


#include <volpack.h>

vpResult vpSetDebug(vpc, flag, value)
vpContext *vpc;
int flag;
int value;

ARGUMENTS


vpc VolPack context from vpCreateContext.

flag Constant that specifies the debugging option to be adjusted.

value New value for the option (boolean: 0 or 1).

DESCRIPTION


vpSetDebug is used to enable or disable a debugging option in a rendering context. The debugging options cause messages to be printed during execution. These messages are probably useless without a good understanding of the source code. If the value option is 0 then the option is disabled; otherwise it is enabled. The following list summarizes all available options:

VPDEBUG_VIEW view transform calculations

VPDEBUG_RENDER high-level rendering stages

VPDEBUG_RBUF intermediate image (render buffer) allocation

VPDEBUG_OPCCORRECT opacity correction

VPDEBUG_DEPTHCUE depth cueing

VPDEBUG_PYRAMID pyramid construction

VPDEBUG_OCTREE octree construction

VPDEBUG_CLSFYOCTREE octree classification

VPDEBUG_OCTREERUNS runs computed from octree

VPDEBUG_OCTREETRAVERSE octree traversal

VPDEBUG_TRANSPOSE volume transposing

VPDEBUG_COMPOSITE compositing

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

ERRORS


The normal return value is VP_OK. The following error return value is possible:

VPERROR_BAD_OPTION The flag argument is invalid.
