| OpenGL Extension #525 |
| OpenGL ES Extension #308 |
| |
| Dependencies |
| |
| This extension is written against the OpenGL 4.6 Specification |
| (Compatibility Profile), dated October 24, 2016. |
| |
| OpenGL 4.5 or OpenGL ES 3.2 is required. |
| |
| This extension requires support for the OpenGL Shading Language (GLSL) |
| extension "NV_compute_shader_derivatives", which can be found at the |
| Khronos Group Github site here: |
| |
| https://github.com/KhronosGroup/GLSL |
| |
| Overview |
| |
| This extension adds OpenGL and OpenGL ES API support for the OpenGL |
| Shading Language (GLSL) extension "NV_compute_shader_derivatives". |
| |
| That extension, when enabled, allows applications to use derivatives in |
| compute shaders. It adds compute shader support for explicit derivative |
| built-in functions like dFdx(), automatic derivative computation in |
| texture lookup functions like texture(), use of the optional LOD bias |
| parameter to adjust the computed level of detail values in texture lookup |
| functions, and the texture level of detail query function |
| textureQueryLod(). |
