How to generate new nurbs curve when move the control point of the start and end control point #241

Closed friends110110 closed 4 years ago

friends110110 commented 4 years ago

In CAD software , I interpolate a nurbs curve , now I want to move the control point of the start and end point , it means move the control point of the start and end control point ? Then how to generate a new nurbs curfve after move the start and end point of the nurbs curve, could return interpolate points of the new nurbs curve. Could provide some c++、java or python code to realize this function?

@mcneel-build could you provide some code(c++ ,java, python code) to move the control point of the start and end point, and evaluate the nurbs curve?

What programming language are you trying to work in? Are you using rhino3dm or is this a general question about Rhino?

friends110110 commented 4 years ago

@sbaer mainly java， but other programming language is also ok. Could you provide some examples?

I just realized that my 2d curve builder sample may be able to help you out here.

A new curve is created from a set of points at this location in the code https://github.com/mcneel/rhino3dm/blob/master/docs/javascript/samples/sketch2d/app.js#L106

Here is a live version of the sample https://mcneel.github.io/rhino3dm/javascript/samples/sketch2d/
