How to apply 4x4 transformation matrix to 3D point?
Answered
I have the following 4x4 transformation matrix:
{ { cos(θ), sin(θ), 0, x * (1  cos(θ)) + y * sin(θ) }, { sin(θ), cos(θ), 0, y * (1  cos(θ))  x * sin(θ) }, { 0, 0, 1, 0 }, { 0, 0, 0, 1 } }
How do I apply it to a 3D point in GeoGebra if I can't represent a point as (x, y, z, w)?
