Point Clouds

Point Clouds in TouchDesigner are achieved via a number of operators, rendering techniques, UI features, file formats and devices.

The Point File In TOP and Point File Select TOP bring point clouds into TouchDesigner, supporting most common point cloud formats and EXR multi-channel files, enabling the conversion of many-channel files into mutiple 4-channel TOPs.

Normalized Split is a display mode of all TOP Viewers where each RGBA channel is visible a grey scale, normalized to the min-max range of the floating point or fixed point numbers in the pixels, showing the min-max values.

View as Points is another display mode of TOPs that treats the RGB channels of an image as XYZ points and displays them in the interactive 3D viewer.

The Point Transform TOP applies 3D transforms, alignments and normalizations on a point cloud.

The Math TOP, Function TOP, Limit TOP and Lookup TOP have been enhanced to support manipulation of pixels as general numeric data, and are aligned closely with their counterparts in CHOPs.

You can render point clouds directly from their representation in TOP as instances in the Render TOP.

Movie File Out TOP has been extended to create many-channel EXR (OpenEXR) files with metadata injected via a DAT. These files can be read back in with the Point File In TOP.

TouchDesigner supports the Kinect Azure's generation of Z-depth images and XYZ+color point clouds.

The Ouster LIDAR system generates long-range point clouds in real-time.

There are some components in the TouchDesigner Palette Components in the Point Clouds section.
