Overview:
The Point File In POP can be used to load 3D point data into TouchDesigner. By default, the x, y, z values are placed in the P attribute while r, g, b, a are placed in the Color attribute. In POPs, we don’t need to think about the XYZ values as RGB color channels as we have previously done in TOPs workflows. These attributes in POPs can be assigned and reassigned as needed, and are not restricted to RGB or groups of 4.
By simply adding a Point File In POP to our network, we can immediately see a sample point cloud (the banana) that has position, texture and color fields automatically assigned. In this topic, we will explore how we can import our own point clouds, reassign UV fields, lookup textures, and load other 3D data.
