Web13 de out. de 2016 · Perspective projection changes the size of an object as it's distance changes, while orthographic projection does not. That is part of the definition of those projection types. To simplify things a bit, a simple perspective projection of a 3d point to a 2d point can be calculated like this: x 2 d = x / z y 2 d = y / z. I'm attempting to set up an orthographic projection in OpenGL, but can't seem to find why this triangle is not rendering correctly (it isn't visible). I have used perspective projection with the same code (apart from my vertex coordinates and projection matrix, of course) and it works fine.
