NAME
vpSetDebug - enable/disable debugging optionsSYNOPSIS
#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.
