RotateBy without AcGe

[Anonymous]

I'm forced to do a datamodel, not using Arx.
And now i need to rotate a vector around another vector.

Anybody happens to have the sourcecode för AcGe ? (just kidding)

But an algorithm to rotate a 1x3 matrix using another 3x1 would be extremely
nice.

Of course both should be 1x3

Try to google it 🙂
You will find enought ready to use libraries.
For ex. in any 3d game you need such a lib so "game programming" should be
good.

I don't want to google it. Got dozens of hits, though
I want to copy-paste it. (ok, i'm lazy, trying to let others do my work).

Thanks.
