11-03-10 / 22:54 : OpenGL 4 annoncé (cjed) | Khronos a annoncé OpenGL4 (spécification seule pour l'instant, il faudra attendre les implémentations), qui inclut les nouveautés suivantes :
- 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.
En attendant OpenGL 3.3 offre certaines de ses fonctionnalités, et peut fonctionner sur les GPU de génération plus ancienne. | | Commentaires | Poster un commentaire | |
