Web23 de ago. de 2024 · OpenGL will automatically scale the rendering so it fits into the given viewport. You do the same for the rest of your viewports and at the end you get one window with few different renderings, each with its own parameters. This way you can have as many distinct renderings on single window/render target as you want. Why it didn't … Web1 de fev. de 2024 · More specifically, the camera is always located at the eye space coordinate (0.0, 0.0, 0.0). To give the appearance of moving the camera, your OpenGL application must move the scene with the inverse of the camera transformation by placing it on the MODELVIEW matrix. This is commonly referred to as the viewing transformation.

OpenGL already handles the division by W part, you don't need to do anything about that. So, this is what a perspective projection matrix should look like: FOV is the vertical angle of the frustum.
