THREE.js - position particles evenly on objects faces rather than verticies

Question

Currently I\'ve managed to create a particleCloud with the particles appearing at each vertex of an object I\'ve imported. However I\'m trying to get the particles to firstl

Answer 1

three.js has some handy methods you can use:

THREE.GeometryUtils.randomPointsInGeometry( geometry, n )

THREE.GeometryUtils.randomPointsInBufferGeometry( geometry, n )

THREE.GeometryUtils.randomPointInFace( face, geometry )

The result may look better if THREE.GeometryUtils.randomPointsInGeometry() ( or BufferGeometry ) is used, as it samples according to face area.

The required GeometryUtils.js file is located in the examples/js/utils directory.
