Interfaces

Print3d

Simple printing functions for vectors, planes, and matrices.

Draw3d

Three-dimensional drawing functions for points, line segments, vectors, curves, and polygons.

Controls3d

Procedures providing three-dimensional control (of vectors, camera angles, etc.).

Render3d

Some procedures providing convenience procedures for clients of ThreeDWorld.

Polygons3d

Miscellaneous procedures related to polygons and triangles.

Misc3d

Miscellaneous procedures.

Commands

Vizer <Shape-File>

Make a line drawing of a polygon model as described by ShapeFile. The file format, essentially a points-polygon file, is the same as used by ThreeDWorld. A sample file, VizerSample.shape, is provided.

The program permits user interaction with the viewing parameters, optional disabling of back-facing polygons, and optional labelling of points.
