Detailed DescriptionThe 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
