3.10 3D graphics interfaces

You can combine Yorick's graphical primitives to create your own graphics interfaces. The Yorick distribution includes a simple 3D graphics interface built in just this way. Study the `pl3d.i' library file if you need an example of how to do this.

Before you can access the 3D functions, you need to include either `plwf.i' or `slice3.i', which provide the highest level 3D interfaces. The `plwf.i' interface lets you plot scalar functions of two variables (like plc or plf). The `slice3.i' interface allows you to plot isosurfaces and slices of scalar functions of three variables. The `demo5.i' demonstration program in the Yorick distribution has examples of both; study it to see how they work in detail.
