The Viewport Matrix in OpenGL - GameDev.net

WebModel, View, Projection and Depth. In a rendering, each mesh of the scene usually is transformed by the model matrix, the view matrix and the projection matrix. Finally the projected scene is mapped to the viewport. The projection, view and model matrix interact together to present the objects (meshes) of a scene on the viewport. WebOpenGL then uses the parameters from glViewPort to map the normalized-device coordinates to screen coordinates where each coordinate corresponds to a point on your …
