API Reference > geometry-core > Polyface > PolyfaceBuilder > addUVGridBody addUVGridBody Method Evaluate (numU + 1) * (numV + 1) grid points (in 0..1 in both u and v) on a surface. Add the facets for numU * numV quads. uv params are the 0..1 fractions. normals are cross products of u and v direction partial derivatives. addUVGridBody(surface: UVSurface, numU: number, numV: number, uMap?: Segment1d, vMap?: Segment1d): void Parameter Type Description surface UVSurface numU number number of intervals (edges) in the u direction. (Number of points is numU + 1) numV number number of intervals (edges) in the v direction. (Number of points is numV + 1) uMap Segment1d optional mapping from u fraction to parameter space (such as texture) vMap Segment1d optional mapping from v fraction to parameter space (such as texture) Returns - void Defined in core/geometry/src/polyface/PolyfaceBuilder.ts Line 1593 Last Updated: 13 June, 2024
