Let me describe the \"battlefield\" of my task: Multi-room audio/video chat with more than 1M users; Custom Direct3D renderer;
I know to use glGet to get various parameters. I need to know how to get the current GL_FRAMEBUFFER_OES and get the GLuint type framebuffer id.
I\'ve googled around everywhere, but cannot find much for rendering strings to textures and then displaying that texture on a quad on the screen. Can someone provide a run-down on开发者_如何学Python t
I am rendering to a texture through a framebuffer object, and when I draw transparent primitives, the primitives are blended properly with other primitives drawn in that single draw step, but they are
