and edgeVisible).
reverseIndices(facetStartIndex?: number[]): void

Type |
Description |
| facetStartIndex |
number[] |
start indices of consecutive facets to be reversed.
* Consecutive indices in this array define where a given facet is represented in each of the parallel index arrays.
* The indices for facet k are facetStartIndex[k] up to (but not including) facetStartIndex[k + 1].
* This implies facetStartIndex[k + 1] is both the upper limit of facet k's indices, and the start index of facet k+1.
* For example, passing an IndexedPolyface's _facetStart array into this method reverses every facet. |
