Mesh

In vvvv there are several options to create a Mesh:

• use the basic primitives like Grid, Box, Sphere from the EX9.Geometry node category.
• load an .x file with XFile (EX9.Geometry Load) exported from a 3d modelling application
• load a .dae collada file using the COLLADA plugin
• create generative geometries with VertexBuffer (EX9.Geometry Join) and Mesh (EX9.Geometry Join)

A Mesh is a data container with two distinct parts: IndexBuffer and VertexBuffer

• the IndexBuffer is a list of integer number triplets, where each triplet defines a triangle of the Mesh and each integer number referes to a vertex in the VertexBuffer.
• the VertexBuffer is a list of all vertices in the Mesh.

Vertex

A vertex is a container itself for data like position, orientation (normal), texture coordinates and so on. But vertex is also often used as a synonym for a 3d position, as the position data is the most important part of it, because with it the shape of the Mesh is defined.
