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. Web22 de abr. de 2008 · Viewport is nice for this application, because it doesn’t depend on the matrix states.

WebAn introduction to matrices. Simply put, a matrix is an array of numbers with a predefined number of rows and colums. For instance, a 2x3 matrix can look like this : In 3D graphics we will mostly use 4x4 matrices. They will allow us to transform our (x,y,z,w) vertices. WebSo, you use glViewport () to determine the location and size of the screen space viewport region, but the rasterizer can still occasionally render pixels outside that region. That's where scissor in comes in. glScissor () defines a screen space rectangle beyond which nothing is drawn (if the scissor test is enabled).
