Hey all,

Can anyone point me to reference with some more details on understanding the 4x4 matrix as it relates to the "Apply Transformation" function?

I kinda get it... but it's been 30-odd years since my last Pre-calculus class and I'm kinda just chasing my tail...

Thank you!

Bob

It's not CloudCompare specific but this covers the basics:

If you don't want to dig in to the math, you can just think of a 4x4 matrix as a convenient way to store a rigid transform (translate, rotate, and scale). That transform can then be applied to a set of 3D points.
