BYU (Movie.BYU geometry) is a file format for computer-aided design and modeling.

It encodes a 3-D object as a collection of polygons and does not include color or textures.

The plottools[exportplot] and plottools[importplot] commands can be used for data exchange between this format and Maple 3-D plots.

The general-purpose commands Import and Export also support this format.

When exporting a 3-D plot to BYU, note that because of the limitations of the format, only GRID, MESH, and POLYGONS plot structures will be exported. All other plot data (for example CURVES or POINTS structures) will be ignored for the purposes of exporting.
