reverseIndices MethodStatic
Reverse the indices for the specified facets in the given index array.
- Parameterized over type T so non-number data (e.g., boolean visibility flags) can be reversed.
reverseIndices<T>(facetStartIndex: number[], indices: undefined | T[], preserveStart: boolean): boolean
| Parameter | Type | Description |
|---|---|---|
| facetStartIndex | number[] | start indices of consecutive facets to be reversed, e.g., an IndexedPolyface's _facetStart array. See the non-static PolyfaceData.reverseIndices. |
| indices | undefined | T[] | the index array, e.g., pointIndex, normalIndex, etc. |
| preserveStart | boolean | true to preserve the start index of each facet (e.g., facet [1,2,3,4] becomes [1,4,3,2]);false to reverse all indices (e.g., facet [1,2,3,4] becomes [4,3,2,1]). |
Returns - boolean
