Control Point Weight Color?


#1

Wouldn’t it be an idea to color the white center of control points red or blue when the weight of the control point is different than 1. Red for 1-10 and blue for 0.1-1. This way it would be more easy to locate weighed points. Now I don’t use weighed control points much as they are more or less hidden.

Thanks.

Do you personally think that this is an improvement?

Hi Pascal, Gerard

This reminds me of a recent wish I did not post about:
Having a curvature analysis for curves.

Yes, I know we have a curvature graph for curves but how about a false coloring like with surfaces.

I myself am almost never using or in any other way aware of controlpoint weights. Is that something commin or more a sort of exotic property that is not really being used (much)? For instance, is it a way to control shape in so called “Class A” surfaces or are those regularly all uniform in weight?

Hi Gerard- yeah… I can see there might be an advantage to knowing about point weighting as one is working. I do once in a while run the Weight command to see if there are any weighted points.

Hi Willem-

Rhino uses weighted points a lot- any arc/ellipse/parabola/circle/cylinder/sphere will have weighted points- these are what the R in NURBS is for - ‘rational’ as in, not all weights the same, some greater then others. The ‘difference’ in weights is what changes the shape of the geometry- weighting all points the same, whatever the number, is the same, shape wise, as all being weighted at one.

They can also used to edit shapes but that is ‘geeky’.
