Projection opengl
The projection matrix is used to create your viewing volume. Imagine a scene in the real world. You don't really see everything around you, only what your eyes allow you to see. If you're a fish for example you see things a bit broader. WebJan 2, 2024 · This optimized method only needs to get P z, which we can compute directly from W z, the depth range, and the three components of the projection matrix: Note that this also means that we don't need the viewport settings in the fragment shader. We only need the depth range and the perspective matrix terms.
