将几何转换为BufferGeometry [英] Transforming Geometry to BufferGeometry

问题描述

据我了解，Geometry存储顶点和面的javascript对象结构，BufferGeometry只通过Float32Arrays等存储原始gl数据。

As I understand it, Geometry stores a javascript object structure of the vertices and faces and BufferGeometry just stores the raw gl data via Float32Arrays, etc.

有没有将标准几何转换为BufferGeometry的方法，这是一个更小的内存紧凑与更少的对象？例如，如果我创建一个新的SphereGeometry，有没有办法轻松将其转换为BufferGeometry？

Is there any way to turn standard Geometry into BufferGeometry, which is a lot more memory compact with less objects? For example if I create a new SphereGeometry, is there a way to easily transform that to a BufferGeometry?

推荐答案

你很幸运。

var bufferGeometry = new THREE.BufferGeometry().fromGeometry( geometry );
