Evaluating the UV parameters of surfaces enables the ability to divide the surface in different patterns. In this video, learn about UV parameters and how to utilize them to create points on a surface.
- [Instructor] So far in the course,…we've learned the basics of Python…and working with different modules and libraries available.…Let's now turn our attention to some…of the common workflows used in Grasshopper,…utilizing Python as we go.…In this video, we'll start by taking…the surface which we created in video five…of section three and we'll create a grid…of points based on the UV directions,…much like the divide surface component does.…By creating the component in Python,…we'll learn how to re-parametrize…a surface and control the UV points.…
If you haven't used UV divisions on a surface before,…U and V are basically a method…of defining a position on a surface,…much like we define XY coordinates on a 2d plane.…Say we had a piece of graph paper…with grids in two directions.…One direction would be the U direction…and the other perpendicular direction…would be the V direction.…Based on where these two directions intersect,…we can create points at these UV coordinates.…In this exercise, we'll loop over…the UV coordinates of a surface…
