Hello, I have been trying to read up on quaternion algebra, and came across the white papers documentation for Chrono. This is a very helpful resource. I have been able to follow the rotations document, however have run into issues with the frame kinematics document.
Specifically, I am struggling to understand, on page 5 in the section Product: the velocity part, how does the following hold true - dq(b,c)/dt . r(a,b) . q*(b,c) + q(b,c) . r(a,b) . dq*(b,c)/dt = 2 dq(b,c)/dt . r(a,b) . q*(b,c) Best, Ashesh Sharma -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
