WebThe view matrix takes three arguments, all three as three-vectors: glm::lookAt (position, focus, up);. The first argument is the position of the camera, the second argument is the focus of the camera (i.e. at which point in space the camera is looking at) and the final argument is the up direction.

I know it may sound weird , but I'm really figuring about a question that w should be unique according to x , as perspective projection calculates w = x/d , where x stands for each vertex's location , while d stays unchanged because it's the distance from the near plane (projected screen) to the focus point.

WebSo I rewrote this post, showing how to correlate a field-of-view angle (typically used to generate an OpenGL projection matrix) and focal length (typically used to determine ray direction).
