| Description |
This package performs a quaternion rotation on a 3-D data set.
The code is written in C, which I have found produces a very significant (> 10X) speedup over a .m file version, allowing for rotation of large 3-D data set in a short amount of time.
"qrot3d" operates on single or double precision data and can take as an input either a quaternion or a rotation vector and angle.
usage:
rotdata = qrot3d(data,quaternion)
or
rotdata = qrot3d(data,omega,theta)
data must be a (Nx3) matrix. "qrot3d" works with both single and double precision. |
| MATLAB release |
MATLAB 7.0.1 (R14SP1)

| Other requirements |
You will need to compile it on your own with a C compiler if you don't have linux or windows. |

Fix a typo that corrupted quaternion rotation for double precision data |
| 25 Sep 2007 |
Update to use new mwSize variable for dimensions (will now run on 2006/2007 versions of MATLAB). Include binaries for windows 32 bit, linux 32& & 64 bit. |
