Any good libraries for quaternion calculations in C/C++ ?
Side note: any good tutorials/examples? I've google it and been to the first few pages but maybe you have have some demos/labs from compsci or math courses you could/would share?
Thanks
You could try with Boost - usually good place to start with. They have a dedicated sublibrary for that.
As for the examples look at the documentation and the unit tests that come along with Boost.
