Geometry Detail

3D Geometry in TouchDesigner is held in SOPs, and is stored in the data structure called a Geometry Detail (Geo-Detail). A Geo-Detail is a comprehensive listing of the entire geometry model that exists within a TouchDesigner SOP at a given time. Geo-Details are generated procedurally by SOPs, and when you save your work into a .geo or .bgeo file, it saves the entire Geo-Detail. The Geo-Detail contains a Point List, a Primitive List, Point Groups, and Primitive Groups. The detail manages Attributes per point, vertex, and primitive, and its own detail attributes.
