Opengl projection matrix field of view
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). This might be useful to you if you need to integrate a raycast volume into an existing 3D scene that uses traditional rendering. Web11 de out. de 2008 · Hi, usually, if the window size changes, you do two things to adjust the OpenGL rendering: Call glViewport () with the new client area size, set up a new projection matrix, e.g. using gluPerspective (). With this standard approach, the display of the rendering changes differently depending on whether you change the width or height of …
