vpSetDebug(3)         DragonFly Library Functions Manual         vpSetDebug(3)

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.
