Hi Gaby, Martin, I'm checking out Martin's graphics framework with a view to using it in my FireAx project. Martin's code is already included in Fricas. When I retrieve scene.spad.pamphlet from here
https://github.com/martinbaker/multivector and then follow the directions here http://www.euclideanspace.com/maths/standards/program/mycode/graph/tutorial/index.htm the spad files don't compile directly under OpenAxiom. I have to change "^" into "**" a few times but have a more serious difficulty with, for instance this in STransform.spad stransform(m:List List DF):% == PT has SCartesian(2) => arr : PrimitiveArray PrimitiveArray DF := new(3,empty()) ... which give the compile error >> Apparent user error: Second argument to has must be a category, or a signature or an attribute PT is of type SPointCategory and SCartesian(n) is a domain constructor that exports SPointCategory() and depends on the dimension n. I assume this error, compared to Fricas situation, is due to divergence in the spad compiler between OpenAxiom and Fricas. Is there a simple way to fix this?
