Keep in mind that the RAM used by the object can rise sharply when using Matrix Extrude — the hairy
sphere example uses hundreds of times more RAM than a standard sphere.

Steps
Denes the number of extrusions for each polygon.
Polygon Coordinates
With Polygon Coordinates disabled, all of the cube’s polygons have been extruded in the same direction.
Matrix Extrude depends on the polygon coordinates system if this option is enabled. If Polygon
Coordinates is disabled, the world coordinates are used for each extruded surface.
Move
Denes the extrusion distance for each step. The Z-axis is the direction of the normal.
Scale
Sets the scale factor for each extruded step. A value of 100% will keep each step the same size as the
base polygon. Values less than 100% result in smaller scaling and values larger than 100% increase
the surface size along the appropriate axis.
