[vtk-developers] Class design for spline visualizations

[David Thompson]

Hi Lin,

> I read the document for BRep format and checked those files in CGM/test. It seems that only a small part of the test files contains bezier/b-spline surfaces and all these files contains quite a number of different kinds of shapes. I can write a class to read such file but it will only display the bezier/b-spline part. I'm afraid that it will just be a piece of the original shape which the file represents. Do you think I should do that or there is a better way to load external shape?

I think it would be great to start with the parts of the CGM files that are NURBS. The remaining shapes should either be straight (lines, planes) or conics (for which you have written a few routines we can use to create patches that will represent them properly).

> PS. I opened a new google doc to summarize what we have done now. I will update new progress to it during the development. (link)

Great!
