GLEW extension loading library V1.3.0 adds core OpenGL 2.0 support

feature graphic

The OpenGL Extension Wrangler Library (GLEW) is a cross-platform C/C++ OpenGL API extension loading library that provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. Core and extension functionality is exposed in a single header file.  The latest v1.3.0 release adds support for core OpenGL 2.0 functionality, custom code generation for lean and mean applications, and a new function for efficient string-based extension queries. GLEW is available for Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

GLIntercept v0.41 adds OpenGL Shading Language shader runtime editing

GLIntercept is an OpenGL API function call interceptor that saves and tracks all OpenGL function calls, display list commands, and textures. It is useful for optimizing OpenGL API-based applications and games. The new v0.41 allows the editing and correction of ARB/NV VP/FP/GLSL shaders/programs at run time , free camera mode that lets you “fly” around the rendered scene to view what actual geometry is sent to the graphics card, and extension/version override so you can test low end rendering pathways without swapping cards.
