| 11-03-10 / 22:54 : OpenGL4 announced (cjed) |
| Khronos announced OpenGL4 (specification only for now, we will have to wait for implementations), that includes the following features : - two new shader stages that enable the GPU to offload geometry tessellation from the CPU; - per-sample fragment shaders and programmable fragment shader input positions for increased rendering quality and anti-aliasing flexibility; - drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention; - shader subroutines for significantly increased programming flexibility; - separation of texture state and texture data through the addition of a new object type called sampler objects; - 64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality; - performance improvements, including instanced geometry shaders, instanced arrays, and a new timer query. Meanwhile, OpenGL 3.3 is aimed at bringing most of OpenGL4 features to older GPUs. |
