Ability to explicitly request that an implementation use a minimum number of unique set of fragment computation inputs when multisampling a pixel ( GL_ARB_sample_shading).Support for double-precision floating-point uniforms, including vectors and matrices, as well as double-precision floating-point data types in shaders ( GL_ARB_gpu_shader_fp64).Many new features in OpenGL Shading Language 4.00 and related APIs to support capabilities of current generation GPUs ( GL_ARB_gpu_shader5 – see that extension specification for a detailed summary of the features).Mechanism for supplying the arguments to a DrawArraysInstanced or DrawElementsInstancedBaseVertex drawing command from buffer object memory ( GL_ARB_draw_indirect).Ability to set individual blend equations and blend functions for each color output ( GL_ARB_draw_buffers_blend).Were performed (GL_ARB_texture_query_lod – this extension only affects Level-of-detail computations that would be performed if a texture lookup Shader texture functions (textureLOD) that return the results of automatic Support for OpenGL Shading Language 4.00, including new fragment.OpenGL 3.3 and 4.0 specifications are available HERE.

Open standard 3D API specification available immediately Provides performance, quality and flexibility enhancements including tessellation and double precision shaders Tight integration with OpenCL for seamless visual computing.Īnd OpenGL 4.0 will officialize the support of hardware tessellation ( GL_ARB_tessellation_shader): very very nice!!! I’ll be able to update my tessellation demo to make it run on both NVIDIA and ATI cards…Īnd I bet (actually it’s sure my friends) that GeForce GTX 480 and GTX 470 will expose these new extensions. GL_ARB_tessellation_shader, GL_ARB_gpu_shader5, GL_ARB_draw_indirect, GL_ARB_shader_subroutine or GL_ARB_texture_gather, here are some of the new features that OpenGL 4.0 will bring.
