<pre><code>v 0 0 0
v 1 0 0
v 0 1 0
v 1 1 0
v 0 0 1
v 1 0 1
v 0 1 1
v 1 1 1

usemtl wood:air
f 1 3 2
f 2 3 4
f 1 5 3
f 3 5 7
f 5 6 7
f 7 6 8
f 4 8 2
f 2 8 6

usemtl wood:brick
f 3 7 4
f 4 7 8
f 1 2 5
f 5 2 6
</code></pre>
<p dir="auto">v代表顶点，f代表三角形，每一个三角形需要定义在某一种material group里面，简单的几何形体或者材料属性比较少的时候可以自己编程实现，针对较复杂的情况是否有比较好的软件或开源程序可以使用？<br />
谢谢大家</p>
