Introduction 1.1. Project/Component Working Name: OpenGL 3.2 for the NVIDIA graphics driver 1.2. Name of Document Author/Supplier: Author: John Martin 1.3 Date of This Document: 19 October, 2009 4. Technical Description This project is the delivery of OpenGL 3.2 / GLSL 1.50 support in the NVIDIA graphics driver. This is an update to OpenGL 3.0 / GLSL 1.30 [LSARC/2009/066] delivered in the R180 driver and OpenGL 3.1 / GLSL 1.40 [LSARC/2009/259] delivered in the R185 driver. The scope of the project is specific to delivery in the NVIDIA graphics driver as OpenGL 3.x introduces a new deprecation model where the intent to remove old features in future releases is declared. The committments to interface stability for this project may not apply to OpenGL 3.x implementations from other vendors. Each of those should be treated as separate projects. The Khronos group (http://www.khronos.org) announced the OpenGL 3.2 and GLSL 1.50 update on 03 August, 2009. Details of this announcement are at: http://www.khronos.org/news/press/releases/khronos-releases-opengl-3.2-third-major-opengl-release-within-twelve-months/ The specifications posted time of this announcement: OpenGL 3.2 Core Profile Specification http://www.opengl.org/registry/doc/glspec32.core.20090803.pdf OpenGL 3.2 Compatibility Profile Specification http://www.opengl.org/registry/doc/glspec32.compatibility.20090803.pdf OpenGL 1.50 Shading Language http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.50.09.pdf New features: ------------- LSARC/2009/066 discussed a new deprecation model introduced in OpenGL 3.0 including the NVIDIA implementation which will deliver deprecated features. To provide optional support of deprecated features, OpenGL 3.2 introduces core and compatibility crofiles. This superceeds the ARB_compatibility extension introduced in OpenGL 3.1 and discussed in LSARC/2009/259 and the compatibility profile restores features removed from the OpenGL 3.1 core specification. Appendix H.1 of the 3.2 Core Specification lists the new features. Deprecation of old features: ---------------------------- As mentioned in the new features section above, core and compatibility profiles are introduced in OpenGL 3.2. The only feature marked for deprecation in the core profile is global component limit query. No feature was deprecated in the compatibility profile by OpenGL 3.2. Details are in Appendix H.2 of the 3.2 Core Specification. Support: -------- Bugtraq: nvidia/nvidia/opengl Delivery: --------- The interfaces listed below are delivered by the NVDAgraphics SYSV package and the NVDAgraphics IPS package, in conjunction with the ogl-select SMF service [LSARC/2005/700]. There are no name changes to the headers or libraries for OpenGL 3.2 so existing build environments are not effected. In the first delivery of this project (driver 190.3x) delivers all of the OpenGL 3.2 and GLSL 1.50 interfaces with the possible following exception: glXCreateContextAttribsARB() does not yet support the GLX_CONTEXT_PROFILE_MASK_ARB attribute value. In order to create a core profile context, call glXCreateContextAttribsARB(), request OpenGL 3.2 as the version, and leave the GLX_CONTEXT_PROFILE_MASK_ARB attribute out. In order to create an OpenGL 3.2 compatibility profile context, call the "old" glXCreateContext() entry point.
