将3D numpy数组保存为.obj文件

Question

I have a 3D numpy array that I generated using some code. I want to save that array as a .obj file to open it in another software like Blender. How do I achieve this?

Answer 1

Have a read of the wavefront obj file format and output your data to match.

Alternatively, you can adjust your script to create the object directly in blender. You would use Blenders bmesh module to create the mesh data. You might be able to find some examples like this at blender.stackexchange where you can ask for more specific help generating the mesh. If you still want the obj file you can export it from blender.

Depending on the algorithm you use to make your mesh, you may also be able to make use of the math function object generators that are in the extra objects addon that is included with blender. This addon is also another place for example scripts.
