| Overview |
| |
| The purpose of this extension is to allow an application to disable all |
| rendering operations emitted to the GPU through the OpenGL rendering |
| commands (Draw*, DispatchCompute*, BlitFramebuffer, etc...). Changes to the |
| OpenGL pipeline are not affected. |
| |
| New preprocessor #defines are added to the OpenGL Shading Language: |
| |
| #define GL_INTEL_blackhole_render 1 |
| |
| New Procedures and Functions |
| |
| None. |
| |
| New Tokens |
| |
| Accepted by the <target> parameter of Enable, Disable, IsEnabled: |
