Quaternion to Vector3D

[ShadowDust]

I've tried and tried and failed at creating a function that takes an Irrlicht Vector3D(used for rotation) and returns a ODE Quaternion and back again.

can some1 with a bit more knowledge at maths then I do this for me, yes I have searched google, and the examples i did find i tried and didn't succeed.

Thanks.

did you search quaternion.h?
It has a constructor which takes euler angles:

Code: Select all

quaternion q(x,y,z);

edit:

back again would be this:

Code: Select all

vector3df v;
q.toEuler(v);

yes, this would be nice, but I'm using Irrlicht.Net, Sorry if i forgot to tell you... perhaps i posted in the wrong forum?
