Dear All,
I'm a new user of ESys, and I have a question about the Rotsphere CheckPointer.
My new question is what Orientation Quarternion Q0,Q1,Q2,Q3 In RotSphere CheckPointer is ? (mentioned in Question #73169 2009-6-03)
As we all know, Euler angle ,with only 3 parameters, is often used to protray the orientation of an object.
