Overview
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

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