geom-merge

Merge a list of geometries (simplicial complex) into one geometry and concat all other attributes.

Installation

npm install geom-merge

Usage

import merge from "geom-merge";
import { cube, sphere } from "primitive-geometry";

const geometry = merge([cube(), sphere()]);

API

merge(geometries): geometry

Parameters

• geometries: Array<geometry> – array of geometry objects

Returns

geometry: { positions: TypedArray | Array | Array<[x, y, z]>, cells: TypedArray | Array | Array<[a, b, c]>, ...otherAttributesMergedAndFlattened: TypedArray | Array } - new geometry with cells, and merged/flattened attributes.

Notes:

• Each geometry object requires at least positions and cells.
• Other array-like attributes like uvs or normals will be merged and flattened, if available in all geometries.
• If the array-like attributes are a mix of Array and TypedArray, the type of the attribute on the first geometry will be used.
• Cells will be chunked if any of the geometries has chunked cells.
• This module doesn't perform CSG operations
