非常简单的3d线条和.obj文件渲染器

Question

我希望在具有多个.obj文件的场景中为一个粘贴人渲染多条3D线。对于可视化，最好在可旋转的环境中渲染这些对象

在python中实现这一点最简单的方法是什么？因为我对图形编程一无所知，所以我想写尽可能少的样板代码

我目前的解决方案是使用cloudcompare提取obj文件的点云，然后使用pyqtgraph与人一起渲染点云。我希望有更好的东西可以让我轻松加载.obj文件。下面是我使用pyqtgraph得到的结果

Here is an example of the obj file

# Blender v2.76 (sub 0) OBJ File: 'table.blend'
# www.blender.org
mtllib table.mtl
