Makes it easy to traverse triangles of three.js's Mesh, Group, BufferGeometry and Geometry object(s).
npm install three-triangle-iteratorthree-triangle-iterator is a simple utility which make it easy to iterate over all the triangular geometry faces of a Mesh, Geometry (in version prior to r125 of three.js) or BufferGeometry objects. It also supports the instanced buffer geometry. This library can work cross platfrom and with your version three.js. This library is backward-compatible with the versions prior to r125 or later.
#### Install
``
yarn add three-triangle-iterator three
or
npm i three-triangle-iterator three
#### Usage
`javascript
import * as THREE from 'three';
import forEachTriangle from 'three-triangle-iterator';
forEachTriangle(object, (triangle) => {
//... do something with each triangle
// Traverse vertices
triangle.forEach((vertex) => {
//... do something with the vertex
})
// Traverse edges
for (let i = 0; i < 3; i++) {
// get the first and next vertex making up the edge
const iNext = (i + 1) % 3;
const edge = {
start: triangle[i],
end: triangle[iNext],
};
//... do something with the edge
}
})
