Unless the field of view is sufficiently narrow?
- Const-me 9y ago> Unless the field of view is sufficiently narrow? Good catch. If the projection matrix is extremely non uniform (e.g. orthographic with very large Z size and very small XY size, or perspective one with FOV angle very close to zero), the described problem can still be encountered. But I did mentioned “a few edge cases”, this is one of them.
