mat4TransformPoint
mat4TransformPoint(
m,p):Vec3
Defined in: src/modules/math/mat4.ts:274
Transform the point p (w = 1) by m, then divide by the resulting w —
so a projection matrix yields NDC directly. Points on the camera plane
(w = 0) divide to ±Infinity; check w via mat4TransformVec4 first
when that matters.
