Creating panels from rationalized surface points results in rectangular planar panels. In this video, learn a different approach, utilizing the UV parameters to split a surface up into a grid to panelize the surface and retain the curvature.
- [Narrator] In the last two videos we have learned…how to create a grid of points on a surface…based on U V parameters.…We'll then use these to create rationalized surfaces.…This is probably the most cost effective way…of constructing our surface, but what if we wanted…each panel to be curved?…To do this, we will need to split the surface up,…rather than reconstruct it.…We can do this by extracting the isocurves of our surface…and then using these to divide the surface up.…Let's give this a try.…We'll be using the same surface and sliders…that we created in this last exercise file.…
So let's go ahead and open up the Python component.…If you're unaware of what isocurves are…they are simply a curve in a constant U…or V direction along a surface.…We can extract all of these…and use these to divide up the surface.…So let's start by looking at the surface methods…to see how we can get the isocurves.…On a new line let's write surface for the input surface…and then dot and isocurve.…
Great, so there's a method.…Let's select that and open parentheses.…
