This function calculates the center, the 2D and 3D surface and positive, negative and
total volume.
First, you select the points that are used for the volume calculation. The order in which
you select the points is not important. Please refer to 2D SURFACE chapter about selection
way. PowerTopoLite generates a mesh (triangulation) of the points automatically and
calculates the result based on the mesh.
The contour of the points will always be convex. A polygon is generated so that an area
may become the biggest. It is like a rope, which is laid around the points, and then tightens.
You have to give the reference height, which is used for volume calculation: the part of
the volume that is situated below the reference height is called negative volume and
the part above the reference height is called positive volume.
NOTE:
Selected points should be less than 350 points.
NOTE:
Relations between each volume and reference height are as follows.
In 3D Volume, the case that input reference height is lower than a solid
Reference Height
Total Volume =
Positive Volume
