Hi Dirk, I was having a look at the Matrix spec [1] and I believe the definitions for pre-multiply and post-multiply are backwards. >From [1]: postmultiply Term B postmultiplied by term A is equal to A · B. >From wikipedia [2]: post-multiply (or right multiply) A by C" means AC Using B and A, as in your text this would give post-multiply (or right multiply) B by A" means BA And likewise for pre-multiply. Could you check please?
