Detailed Description

Various aspects of the Coin runtime behaviour can be controlled through setting different environment variables to some value. Most of these variables are there for debugging and problem-workaround purposes, but a few are for telling Coin where to locate external resource files.

Here we will set up a list of some of the environment variables Coin will check for and can alter behavior because of. Scene Graph Profiler The scene graph profiler subsystem uses the following environment variables:

COIN_PROFILER
COIN_PROFILER_OVERLAY

A lot of other environment variables will also affect the profiling and listing them all would be tedious. Most useful is perhaps the IV_SEPARATOR_MAX_CACHES variable for disabling caching, and those that disable features like vertex arrays and frame buffer objects, but using thise will of course cause you to profile special cases that may not be as important as you might think.

EnvironmentVariable COIN_FONT_PATH

 

EnvironmentVariable COIN_GLBBOXIf the environment variable COIN_GLBBOX is set to 1, rendering action traversals will apply a bbox action before rendering. This will make sure bounding box caches are updated (needed for view frustum culling). The default Quarter/SoQt/SoWin/SoXt viewers will handle this at their end (which is the proper way to do it), so we don't do this by default.

EnvironmentVariable COIN_QUADMESH_PRECISE_LIGHTING

 

EnvironmentVariable COIN_ENABLE_CONFORMANT_GL_CLAMP

 

EnvironmentVariable IV_SEPARATOR_MAX_CACHESCan be used to tune the number of display list caches stored in each SoSeparator. The default value is 2.

Setting this value to 0 will disable display list caching, and this is often useful if you experience weird rendering bugs which are hard to track down.

EnvironmentVariable COIN_AUTOCACHE_LOCAL_MIN

 

EnvironmentVariable COIN_AUTOCACHE_REMOTE_MAX

 

EnvironmentVariable COIN_AUTOCACHE_REMOTE_MIN

 

EnvironmentVariable COIN_AUTO_CACHING

 

EnvironmentVariable COIN_ENABLE_VBO

 

EnvironmentVariable COIN_VBOSet COIN_VBO=0 to disable VBO rendering in Coin. This is useful if you suspect bugs in either Coin's VBO code or in the OpenGL driver VBO handling.

 

EnvironmentVariable COIN_VBO_MAX_LIMITCan be used to set the maximum number of items (coordinates, normals, texcoords or colors) allowed when creating a vertex buffer object. On most drivers it's actually slower to render large arrays with VBOs than with normal vertex array rendering.

The default value is 256000, and when the number of items exceeds this Coin will fall back to normal vertex array or immediate mode rendering.

See also:

COIN_VBO_MIN_LIMIT

 

EnvironmentVariable COIN_VBO_MIN_LIMITCan be used to set the minimum number of items (coordinates, normals, texcoords or colors) allowed when creating a vertex buffer object. It's a bit of overhead setting up the VBOs and the VBO rendering, so we avoid doing this for very small arrays. The default value is 20.

COIN_VBO_MAX_LIMIT

 

EnvironmentVariable COIN_SOOFFSCREENRENDERER_ALLOW_RESOURCEHOG

 

EnvironmentVariable SO_DRAGGER_DIR

 

EnvironmentVariable SO_SHADER_DIR

 

EnvironmentVariable COINDIR
