calcMassProp( Geom, Density,
Resolution )
-
Calculate mass properties for a set of objects assumed to represent a closed
surface bounding a volume. The input can be tensor product surfaces, polygons,
or both.
-
Returns
-
<matrix> matrix containing Surface area, Volume, Density, Mass, Centroid,
X moment, Y moment, Z moment, XY product, YZ product, ZX product, Inertias
at the centroid, Principal axes and inertia
-
Geom
-
<any> If either the object or its geometry is a shell, tensor product
surfaces, or polygons, we can use it.
-
Density(1.0)
-
<number> (Optional) The density to use (mass per
unit volume.)
-
Resolution(0.01)
-
<number> (Optional Numerical resolution to use in
the calculation.
-
Example
s:makegeom(unitsphere);
calcmassprop(s); # simple, fast
calcmassprop(s,2.0,0.001); # slower, more accurate, 2x density
