The major features of GL4 include: hardware tesselation support, ability to dynamically link shader subroutines, ability to set individual blend equations and blend functions for each color output and a mechanism to supply the arguments to certain Draw functions from buffer-object memory.

Release Dates:

  • OpenGL 4.0: March 11, 2010
  • OpenGL 4.1: July 26, 2010
  • OpenGL 4.2: August 8, 2011

OpenGL square stretches instead of moving

I'm attempting to create a game engine using LWJGL3 (Open GL 4.1, NVIDIA-10.8.14) in Java, but I seem to have run into a *small* problem... When I attempt to translate the square, instead of actually moving as expected, it ends up stretching. LWJGL…
