Hi!

For a project, I made a visualisation of a vector calculation (with draw_line3d() etc.). Now I want to port the calculation to a micro controller. So I have to code all vec_...() functions for my own.
The problem is, that the vec_rotate() algorithm wasn't added to the manual. Does anybody know how to write a function that does something similar? I searched the internet, but it seems to be very difficult => a micro controller isn't that fast, so it should be something with less instructions.

Thanks for your help!
