addFacetFromGrowableArrays Method

Add a polygon to the evolving facets.

  • Add points to the polyface.
  • Compute each point index as the point is added.
  • All data arrays are parallel to the point array.
  • Point indices are added in reverse order if indicated by the builder state.

addFacetFromGrowableArrays(points: GrowableXYZArray, normals: GrowableXYZArray, params: GrowableXYArray, colors: number[], edgeVisible?: boolean[]): void

Parameter Type Description
points GrowableXYZArray array of vertices in order around the facet.
normals GrowableXYZArray (optional) array of normals, one per vertex.
params GrowableXYArray (optional) array of uv-parameters, one per vertex.
colors number[] (optional) array of colors, one per vertex.
edgeVisible boolean[] (optional) array of flags, one per vertex, true iff edge starting at corresponding vertex is visible.
