Detailed Description

The SoGLDriverDatabase class is used for looking up broken/slow features in OpenGL drivers.

Coin will maintain a database of drivers where we have found problems with certain features, even if the OpenGL driver claims to support it. This is an effort to avoid application or operating system crashes when Coin attempts to use a specific feature. Using this database we can either disable this feature, or find another way to handle it for broken drivers.

Member Function Documentation

SbBool SoGLDriverDatabase::isSupported (const cc_glglue * context, const SbName & feature) [static]

Convenience function which checks whether feature is suppported for context. If feature is an OpenGL extension, it checks if it's actually supported by the driver, and then calls SoGLDriverDatabase::isBroken() to check if the feature is broken for context.

SbBool SoGLDriverDatabase::isBroken (const cc_glglue * context, const SbName & feature) [static]

Checks the driver database to see if feature is tagged as broken.

SbBool SoGLDriverDatabase::isSlow (const cc_glglue * context, const SbName & feature) [static]

Checks the driver database to see if feature is tagged as being slow.

SbBool SoGLDriverDatabase::isFast (const cc_glglue * context, const SbName & feature) [static]

Checks the driver database to see if feature is tagged as fast.

SbName SoGLDriverDatabase::getComment (const cc_glglue * context, const SbName & feature) [static]

Get the comment for feature in context, returns 'undefined' if the feature has no entry. Provides extensibility to the database.

void SoGLDriverDatabase::loadFromBuffer (const char * buffer) [static]

Load the driver database from buffer

void SoGLDriverDatabase::loadFromFile (const SbName & filename) [static]

Load the driver database from the file specified in filename

void SoGLDriverDatabase::addBuffer (const char * buffer) [static]

Add the XML data in buffer to the driver database

void SoGLDriverDatabase::addFile (const SbName & filename) [static]

Add the XML data in filename to the driver database

void SoGLDriverDatabase::addFeature (const SbName & feature, const SbName & comment) [static]

Add a feature to the driver database
