The draw call does not change either, you just have to set the right number of vertices that must be drawn :. (I know that is super vague, but i'm starting out very small) I'd like to use c++ with glfw and opengl. If you do not have OpenGL continuously loaded due to, for example, a compositing window manager, then the driver must be initialized every time you launch your OpenGL application, slowing down startup by 300ms. We use a lambda to specify how to compute each element of the result matrix. In _GL_TRIANGLE_FAN mode, OpenGL draw a connected group of triangles from a origin which is (0,0,0) by default. Features: 100% pure Java port, native libraries are used only for OpenGL access in demos; ported most of Bullet 2.
