vpContext *vpc;

Constant that specifies the debugging option to be adjusted.

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.
