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 records the entire geo-detail.


The geo-detail contains a Point List, a Primitive, Point Groups, and Primitive Groups. The detail manages attributes per point, vertex, and primitive, and its own detail attributes.
