sumVolumeBetweenFacetsAndPlane MethodStatic
Sum (signed) volumes between facets and a plane.
sumVolumeBetweenFacetsAndPlane(source: PolyfaceVisitor | Polyface, plane: Plane3d, skipMoments?: boolean): FacetProjectedVolumeSums
@returns a structure with multiple sums:
- volume: the sum of (signed) volumes between facets and the plane.
- positiveProjectedFacetAreaMoments, negativeProjectedFacetAreaMoments: area moment data (centroid, signed area, and second moments with respect to the centroid), separately computed for the input facets that project with positive/negative area onto the plane.
| Parameter | Type | Description |
|---|---|---|
| source | PolyfaceVisitor | Polyface | facet set |
| plane | Plane3d | infinite plane bounding volume between the input facets and (virtual) side facets perpendicular to the plane. |
| skipMoments | boolean | whether to skip computation of the area moments. Set to true if only volume is needed. Default is false. |
Returns - FacetProjectedVolumeSums
a structure with multiple sums:
- volume: the sum of (signed) volumes between facets and the plane.
- positiveProjectedFacetAreaMoments, negativeProjectedFacetAreaMoments: area moment data (centroid, signed area, and second moments with respect to the centroid), separately computed for the input facets that project with positive/negative area onto the plane.
