OpenSCAD has matrix multiplication built in. E.g. ma * mb. On Sat, 4 May 2019 at 15:49, ats3788 <ats3788@gmail.com> wrote: > What a wonderful Artwork Perfect to fiddle with.

You might mean things like [1,2,3]*[4,5,6]. Matrices passed into m_multiply have the data structure [[1,2,3],[4,5,6]] required by multmatrix. ----- http://openhome.cc -- Sent from: http://forum.openscad.org/

I didn't know it!!!! Thank you very much!!!! ----- http://openhome.cc -- Sent from: http://forum.openscad.org/

Your first examples are vectors and I think it does the dot product in that case but if you pass matrices as your second example it does matrix multiplication as long as the dimensions are compatible. In you case 4 x 4 will work fine.

Yes, you are right. I soon found that 4 x 4 will work fine so I deleted my origin reply :p Thank you very much again. It helps a lot! ----- http://openhome.cc -- Sent from: http://forum.openscad.org/
