OpenGL ES 3.0 is backwards compatible with OpenGL ES 2.0 while drawing on features from OpenGL 3.3 and OpenGL 4.2.Īmong the OpenGL ES 3.0 features are enhancements to the rendering pipeline (occlusion queries, transform feedback, instanced rendering), ETC2/EAC texture compression, a new version of the GLSL ES shading language, and enhanced texturing functionality.

#OPENGL 4.3 UPDATE#

Right now we're not even looking at OpenGL 3.1 until early 2013.įor mobile and other scenarios, OpenGL ES 3.0 was also released as the first update to OpenGL for Embedded Systems since 2007. For the open-source Mesa/Gallium3D support, we're realistically not looking at that support to arrive until 2014 or later unless there's some significant investments made.

AMD will likely put out a new beta of their AMD Catalyst Linux/Windows drivers soon to enable preliminary OpenGL 4.3 / GLSL 4.30 support soon.

In traditional NVIDIA fashion, they already have beta OpenGL 4.3 proprietary drivers (Linux support included) at. New functionality provided by the OpenGL 4.3 specification includes: compute shaders leveraging GPU parallelism within the context of the graphics pipeline, shader storage buffer objects, texture parameter queries, high-quality ETC2/EAC texture compression as a standard feature, debug capabilities to receive debugging messages during application development, texture views for interpreting textures in different ways without data replication, increased memory security, and a multi-application robustness extension. It's been twenty years since the release of the original OpenGL specification and this royalty-free multi-platform graphics specification keeps moving forward. Then during draw you keep the vao bound and only change the buffer bindings.Just as I reported last week would happen at SIGGRAPH and in late May first talked about OpenGL ES 3.0, today at the first day of SIGGRAPH LA 2012 the Khronos Group announced the release of the OpenGL 4.3 and OpenGL ES 3.0 graphics API specifications.

accessible constant declarationsĬonstexpr int texBindingPoint = 1 // free to choose, must be less than the GL_MAX_VERTEX_ATTRIB_BINDINGS limit You can also change the buffer that provides data to multiple attributes with a single bind call. By separating the two, you can bind buffers without respecifying any vertex formats. The binding point specifies which buffer an attribute takes its data from. The vertex format consists of the type, component count, whether it is normalized, and the relative offset from the start of the data to that particular vertex. So instead of having a VAO per mesh, you may have a VAO per vertex format.Įach attribute is associated with a vertex format and a binding point. OpenGL 4.3 (or ARB_separate_attrib_format) adds an alternative way of specifying the vertex data, which creates a separation between the format of the data bound for an attribute and the buffer object source that provides the data.
