The latest release of “Essential Mathematics for Computational Design“, Rajaa Issa demonstrates the underlying mathematical concepts that make CAD possible, from Vectors, to continuity types, to matrix algebra and parametric curves. The overview is very high-level, but if you enjoy math like I do, this is a real treat. Geek out!

This week we’ll be taking a brief look at “patch layout” for NURBS modeling, the fundamental concept underlying surface modeling in any surfacing package, be it Rhino, Alias, ICEM, SolidWorks, ProE/ISDX, UGNX, Catia, or Bob’s Pretty Good CAD. You already know how to “see” the building-block shapes that make up simple geometric designs, but a [...]
