as you are probably guessing by the title I'm not a math guy. The program I use for work has matrix which describes the position of a plane in 3d space. The center point of that card / plane can be easily read from the matrix. But the matrix also contains information regarding rotation (which I am guessing is in rad) and scale. I wondered if you could calculate the normal vector for the center point using this matrix data (maybe from the rotation?) to describe the plane.
The next question would be how to calculate the 3d positions of the 4 corner points of a square in this plane given a user set the distance from the center.
Thanks for taking the time explaining. picture of matrix here
