GL_ARB_internalformat_query2: find out actual supported limits for most texture parameters.GL_ARB_fragment_layer_viewport: gl_Layer and gl_ViewportIndex now available to fragment shader.GL_ARB_explicit_uniform_location: set location of a default-block uniform in the shader.GL_ARB_copy_image: direct copy of pixels between textures and render buffers.GL_ARB_compute_shader: introduces new shader stage and enables advanced processing algorithms that harness the parallelism of GPUs.GL_ARB_clear_buffer_object: clear a buffer object with a constant value.GL_ARB_ES3_compatibility: brings EAC and ETC2 texture compression formats.GL_ARB_arrays_of_arrays: allows multi-dimensional arrays in GLSL.Here are the new that should be exposed by an OpenGL 4.3 driver:
You can find the complete specification HERE or you can use these New functionality in the OpenGL 4.3 specification includes: – compute shaders that harness GPU parallelism for advanced computation such as image, volume, and geometry processing within the context of the graphics pipeline – shader storage buffer objects that enable vertex, tessellation, geometry, fragment and compute shaders to read and write large amounts of data and pass significant data between shader stages – texture parameter queries to discover actual supported texture parameter limits on the current platform – high quality ETC2 / EAC texture compression as a standard feature, eliminating the need for a different set of textures for each platform – debug capability to receive debugging messages during application development – texture views for interpreting textures in many different ways without duplicating the texture data itself – indirect multi-draw that enables the GPU to compute and store parameters for multiple draw commands in a buffer object and re-use those parameters with one draw command, particularly efficient for rendering many objects with low triangle counts – increased memory security that guarantees that an application cannot read or write outside its own buffers into another application’s data – a multi-application robustness extension that ensures that an application that causes a GPU reset will not affect any other running applications.
The new features of OpenGL 4.3 are summarized here: And full backwards compatibility is maintained with old fixed functions. Among the new features, OpenGL 4.3 brings the support of a new kind of shader, the compute shader via the GL_ARB_compute_shader extension. The Khronos Group has released today, at the SIGGRAPH 2012, the OpenGL 4.3 specification.
