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.
