combining transform matricies

#1

I know this is a pretty noobie question… am i correct in saying that transform matricies can be combined but matrix multiplication into on single transform matrix?

If so then i am getting very wrong results :frowning:

if not then could someone tell me how to go about combining these matricies?

#2

combining by multiplication is correct. But order matters (e.g. when ‘combining’ a translation and a rotation).

Another option is be to cascade tranfromgroups, but this is another thing.

#3

I understand that order is important… my transform matricies have abritrary values in the 4x4 matrix. i.e. it can be a scale,translation,rotation or some or all of them.

I am leading to believe that my problem may not lie with the obvious (the translation matrix) and may be some where else.

Thanks anyway.
