Web21. feb 2024 · If I understood it right, for perspective projection, the general matrix inversion is used. (May be, it is applicable for projection matrices properly built with QMatrix4x4::perspective().) However, it couldn't hurt to use/check the invertible argument of QMatrix4x4::inverted() (just to be sure). – Web14. feb 2024 · v ′ = L v + t. where L is a linear transform and t is the translation, we can do. v ′ = A v. Where A is the affine matrix. This makes it cleaner. So 4x4 matrices are a real necessity, we just can't work without them. In order to distinguish between vectors and points we use w = 1 for points and w = 0 for vectors.

Web6. apr 2015 · The complicated (real) perspective matrix has a "1" on the bottom row. This stores the z value aka depth into the w coordinate, while the x, y and z get scaled into clip space, according to the angle of view and the near and far planes. But the division by z can't be coded in a matrix. This perspective divide is done afterwards.

WebIt kind of makes sense that you have to do a perspective divide after applying the inverse projection transform - after all it's going to alter the x,y,z and w components of the result in projecty ways, but I don't understand why this would then correctly give you back the original world space position for the fragment instead of an arbitrary ...
