convert/POLYGONS

convert GRID and MESH structures into POLYGONS

 Calling Sequence convert( p, POLYGONS ) convert( p, POLYGONS )

Parameters

 p - PLOT3D structure; or GRID/MESH structure; or a list of GRID/MESH structures

Description

 • This routine converts MESH and GRID structures into POLYGONS structures. If the first argument is a GRID or MESH structure, then the result is a equivalent POLYGONS structure; if p is a list of GRID and MESH structures, then the result is a list of corresponding POLYGONS structures; if p is a PLOT3D structure, then the result is a list of POLYGONS structures corresponding to GRID and MESH structures in p.

Examples

 > $p≔\mathrm{plot3d}\left(\mathrm{sin}\left(xy\right),x=-1..1,y=-1..1,\mathrm{grid}=\left[3,3\right]\right):$
 > $\mathrm{p2}≔\mathrm{convert}\left(p,\mathrm{POLYGONS}\right):$
 > $m≔\mathrm{MESH}\left(\left[\left[\left[1,2,3\right],\left[4,5,6\right]\right],\left[\left[7,8,9\right],\left[1,2,3\right]\right]\right]\right):$
 > $\mathrm{convert}\left(\left[m\right],\mathrm{POLYGONS}\right)$
 $\left[{\mathrm{POLYGONS}}{}\left(\left[\left[{1}{,}{2}{,}{3}\right]{,}\left[{4}{,}{5}{,}{6}\right]{,}\left[{1}{,}{2}{,}{3}\right]{,}\left[{7}{,}{8}{,}{9}\right]\right]\right)\right]$ (1)
