pymel.core.system.openGLExtension

static system.openGLExtension(*args, **kwargs)

Command returns the extension name depending on whether a given OpenGL extension is supported or not. The input is the extension string to the -extension flag. If the -extension flag is not used, or if the string argument to this flag is an empty string than all extension names are returned in a single string. If the extension exists it is not necessary true that the extension is supported. This command can only be used when a modeling view has been created. Otherwise no extensions will have been initialized and the resulting string will always be the empty string.

Flags:
Long name (short name) Argument Types Properties
extension (ext) unicode ../../../_images/create.gif
 
Specifies the OpenGL extension to query.
renderer (rnd) bool ../../../_images/create.gif
 
Specifies to query the OpenGL renderer.
vendor (vnd) bool ../../../_images/create.gif
 

Specifies to query the company responsible for the OpenGL implementation. Flag can have multiple arguments, passed either as a tuple or a list.

version (ver) bool ../../../_images/create.gif
 
Specifies to query the OpenGL version.
