threejs如何计算立方体的面积和体积？
网友回复
可以通过faces与vertices结合Triangle运算获取立方体各个面的面积
示例代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum=1.0,minimum=1.0,user-scalable=0" />
<script type="text/javascript" src="//repo.bfw.wiki/bfwrepo/js/three.js"...点击查看剩余70%

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum=1.0,minimum=1.0,user-scalable=0" />
