Status of OpenGL 3.x features in Mesa
|
||
|
|
|
||
|
|
|
||
|
|
Note: when an item is marked as "DONE" it means all the core Mesa
|
||
|
|
infrastructure is complete but it may be the case that few (if any) drivers
|
||
|
|
implement the features.
|
||
|
|
|
||
|
|
|
||
|
|
OpenGL Core and Compatibility context support
|
||
|
|
|
||
|
|
OpenGL 3.1 and later versions are only supported with the Core profile.
|
||
|
|
There are no plans to support GL_ARB_compatibility. The last supported OpenGL
|
||
|
|
version with all deprecated features is 3.0. Some of the later GL features
|
||
|
|
are exposed in the 3.0 context as extensions.
