Subject:[Bf-committers] Change Representation and Initialisation of Matrices to Conform with Standard Notation
From:Andrew Hale (trum@gmail.com)

Hi All,

I have written a patch which rectifies a cause of confusion among Blender uses when starting out with matrices and vectors. The patch ensures consistency between the matrix representation and matrix/vector products so that they behave in the way that people familiar with math expect. This is achieved by adjusting pythons access to the internal storage, while keeping the internal data the same. Note that this does not interfere with how matrices are stored internally or how matrix products, additions etc are performed internally.

The patch can be found here: http://projects.blender.org/tracker/index.php?func=detail&aid=29534&group_id=9&atid=127along with a more in depth explanation.

Thanks, Andrew
