![]() ![]() ![]() What does this mean when Rhino reads this data and tries to display a mesh? Take the example in the image below. In the face list, the vertices contain the indices for the vertices, and not the coordinates of the vertices themselves. For each face, we define three vertices for triangles called A, B and C, or four vertices for quads, A, B, C and D. For each point, we can also imagine an index. For example, the fourth point in the list has an index of 4. In terms of data structures, a mesh contains 2 lists:įirstly, we define a list of vertices. A single mesh can contain as many faces and vertices as you want. How does Grasshopper handle this? The basicsĪ mesh is a collection of faces. They are a form of geometry that contain a collection of faces, and that each face can have no more than 4 corners. You probably already know a little about meshes. They have a somewhat unintuitive data structure that can make it hard to handle meshes in C# code. Understanding meshes in Grasshopper can be a little tricky. ![]()
