如何使用three.js绘制自定义3d曲面? [英] How do I draw a custom 3d surface using three.js?

问题描述

我要使用什么功能/数学来绘制3d曲面?例如，如何生成z = sin(x + y)?如何计算和绘制点?我找不到任何例子.

What functions/math do I use to draw a 3d surface? For example, how do I generate z = sin(x+y)? How are the points calculated and drawn? I couldn't find any examples.

推荐答案

https: //threejs.org/docs/#api/en/geometries/PlaneGeometry

类似这样的东西包含顶点.如果顶点由[x，y，z]组成，则可以通过遍历所有顶点在此处应用函数.

Something like this contains vertices. If a vertex consists of [x,y,z] you can apply your function there by looping through all the vertices.
