ARBcopyimage support of OpenGL 4.3 has been implemented for R600g. However on the Desktop both nVidia and AMD support the compatibility profile, so your old OpenGL programs should work. AMDs R600 Gallium3D driver just made it up to OpenGL 4.1 support (for the few select GPUs that provide the necessary capabilities), but things arent stopping there with another OpenGL 4.3 extension now landing. datenwolf at 22:41.In Linux, compile with the provided makefile or the following: g++ Trackball.cpp -o trackball -lGL -lglut -lGLU. The core profile is upward compatible from 3.1, and the compatibility profile is upward compatible all the way from OpenGL 1.1.īut the compatibility profile is not required for OpenGL compilance, so the driver writers may chose to provide only the core profile in which case your 2.1 programs may not work. In a more sophisticated implementation (say an arcball) the scaling may even depend on the position of the pointer relative to where the motion started.However in Version 3.2 the ARB defined the concept of GL “profiles” and defined the “core” and “compatibility” profiles. Most OpenGL versions are upward compatible, the only GL version which removed some APIs was the Version 3.1. lib files will be different in GL 4.3, so will my code that I wrote with GL 2.x still compile with GL 4.3? Just out of curiosity, do we still use glut in GL 4.3? I guess the. I’m planning on getting a new PC soon, just wondering where I stand. I’m actually using the graphics chipset on my motherboard, which worked fine when programming GL 2.x.
