Use this caddy to specify how Tessellate subdivides polygons.
For details on using the caddy controls, see The Caddy Interface.

Choose the tessellation method from the drop-down list:
EdgeInserts vertices in the middle of each edge and draws lines connecting those vertices. The number of polygons created equals
the number of sides of the original polygon.
FaceAdds a vertex to the center of each polygon and draws connecting lines from that vertex to the original vertices. The number
of polygons created equals the number of sides of the original polygon.
TensionLets you increase or decrease the Edge tension value. Available only when the Edge tessellation method (see preceding) is active.
A negative value pulls vertices inward from their plane, resulting in a concave effect. A positive value pulls vertices outward from their plane, resulting in a rounding effect.
