The image gives some test examples that use fat Bezier patches, made up of fat
strips. fat fans, fat triangles or fat quadrilaterals.
The arrowhead is a single fat Bezier triangular patch (with its reflection) with
a hollow cylinder attached to one of the vertices. The Starck Juicer was the
subject of a recent set of posts. The body is mainly sphere sweeps (of a single
Bezier segment variety - I like the control) The legs are two fat strips.
I like the knife, which needs two fat fans, three fat strips - one specifically
the transition region.
The glasses are produced with a glass making #macro, using the sphere blends and
hollow roundcone.
The #macros in use do need e.g. eight vectors and eight radii for a strip, ten
for a triangular patch and sixteen for a quadrilateral patch. Challenging, but
not impossible for an object using very few patches - the seat and back of the
chair are each made of a single quadrilateral patch.
For static objects, there may be no advantage (and a disadvantage of needing
good 3D visualisation to input the co-ordinates and radii) over a modeller.
However, it is possible to parameterise some of the co-ordinates or radii to
simply change a shape, as in the next post to this thread.
