[RANDOM POLYGONS ON THREE SPHERES]
WORKSPACE POLY3CLOUDS DESCRIPTION:
This workspace shows how to use ASPL operators to do contextual set operations on geometric data. Worspaces that have a name suffixed with GEO causes ASPL to switch it f& and f\ to do contextual set intersection and set difference according to contextual routines, here they are the GEOmetric routines. This workspace shows the power of ASPL set operators when performing operations on geometric data set. In this example we will call the GG function ggRPO3Sov() to create 100 polygons, namely triangles, on three spheres. The result is assigned to S123_100, and the labeling of the spheres are S1, S2, and S3. We will split the resulting set variable S123_100 into three set variables S1, S2, and S3. We will call f& on S1 and S2 to get their intersects, and the result is pushed on the stack. We will call f& on S1 and S3 to get their intersects, and the result is pushed on the stack. We will call f& on S1 and S3 to get their intersects, and the result is pushed on the stack. We will call f& on S1 S2 S3 to get their intersects, and the result is pushed on the stack. We will pop the stack and assign the results to S123, S23, S13, S12, S23 respectively. Finally we will dump the GADg of the variables so that we can plot them with drawgad command. Read the ASPL book on how to create GEO workspaces. In this tutorial the 'aspl>' refers to the ASPL prompt, and the '#' refers to the shell prompt.
