FORMAT C3D

A geometric model can be saved in a compact form to a memory buffer or a disk file. There are two types of C3D format for storing a geometric model – compact and extended.

This article describes C3D formats for storing a geometric model and the interfaces the kernel provides for writing and reading geometric model data in the C3D format.
