Free TouchDesigner 2022 Component: Fulldome Planetarium Projection Simulator (INFRA)

Overview

INFRA (theinfranet) shares the TouchDesigner Fulldome Simulator, a lightweight component that wraps any 2D or 3D visual onto a virtual dome to preview how it deforms in a real fulldome environment. It offers three dome templates, a configurable input TOP, dome tilt, an interactive camera for viewing from the spectator's position and a sweet-spot grid, and 3D content has to be rendered in FishEye Equidistant (180°) mode.

Seven example files range from 2D and 3D basics to dome point clouds, a PLY point cloud, a RayTK fractal and experimental POPs sphere-field and Gaussian-splatting scenes. It was developed in TouchDesigner 2022 for a meetup at a Chilean planetarium and is a free direct download from GitHub.
