| 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. |
