Matt, maybe it was the same textbook? :) I forget the author but as I recall it
was a grey hardback with pinkish/purplish printing on the front.

Yes, a linear algebra book will tell you what you need to know in the
context of ICE to KNOW that.
"Positions converted with 4x4 and locations with 3x3" is scarily incorrect
and highly coincidental.
I really, really do recommend some fundamentals of linear algebra if you're
getting deeper into ICE

Joey,
ICE doesn't convert locations directly. It can display them as vectors for
debugging purposes but under the hood they are really a triangle ID +

It will differentiate how to handle orientation vectors differently from
position vectors which is the solution to the problem you said you couldn't
solve on your own.

I tried this already, but it didn't work. Rather, it works but not how I need
it to work. So
I've got two point positions, a vector is derived from these point positions.

Howdy,
I'm trying to get a vector which is the normal of a surface relative to world
space, not local space. The object is moving. I managed to get the vector using
both PointNormal and SurfaceGeometricNormal. Sometimes the calculations work
and sometimes they don't. It appears when I display t
