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.
