expressing multmatrix in translate and rotate?
Hello Everybody
Openscads rendering speed on complex models is really difficult to
tolerate to me, it really slows down my work by an order of magnitude.
I was thinking of trying to export CSG from openscad and trying to feed
into impicitCad, in the hope it will be rendering much faster.
Strangely implicitCad does not know multmatrix, so i would like to
replace it by some translate rotate or scale combination automatically.
is it even possible without an equation solver?
Anybody has an idea on how to do it?
Thanks Peter
Peter:
Have you tried using AngelCAD? For some OpenSCAD scripts, AngelCAD is
stunningly faster when generating an STL.

You can compose translate, rotate, scale and skew into a single matrix but
I doubt there is a unique way of separating them out again.

Hello Nophead, the solution does not have to be unique. i am happy with
any solution, since it will compile into the same matrix in the end
anyway, i just wonder if it is possible without solving equations

I have a function that recovers a rotation from a rotation matrix here:
https://github.com/nophead/NopSCADlib/blob/master/utils/maths.scad#L107
Translate is easy as that is just the fourth column or row depending on
which way round it is, I forget.
