Re: Help on rotation using quaternions or YPR

<r>I wanted to post a more specific solution to the OptiTrack environment. I am using Matlab, but an implementation in C/C++ should be easily derived from the below results.<br/> <br/> If using the API output, I understand that the convention is for a left-handed coordinate system. OptiTrack has C++...

Re: Help on rotation using quaternions or YPR

<t>In order to transform from one coordinate system to another using the Euler yaw pitch and roll angles or the quaternions, there are several key assumptions that must be known. Since this is such a common practice that might be done with the data from the tracking tools, it would have been expecte...
