I'm working on a method to compare distances in a space in Python. I am only using the GUI to check my results; all operations are done via a Python script.

I am using the remesh operator to increase the number of faces of a given primative, so that I can find a pseudo-accurate distance to the object by finding the closest face.

I was able to get the remesh to work. However, I'm having trouble accessing the new polygons. It seems there are only the original centers available.. although I am able to see when loading Blender that the number of faces have increased. So, the number of face-centers should also?!

Before: before remesh

After: after remesh

In the console:

>>> ob.data.polygons[:]
[bpy.data.meshes['slab'].polygons[0], bpy.data.meshes['slab'].polygons[1], bpy.data.meshes['slab'].polygons[2], bpy.data.meshes['slab'].polygons[3], bpy.data.meshes['slab'].polygons[4], bpy.data.meshes['slab'].polygons[5], bpy.data.meshes['slab'].polygons[6], bpy.data.meshes['slab'].polygons[7], bpy.data.meshes['slab'].polygons[8], bpy.data.meshes['slab'].polygons[9], bpy.data.meshes['slab'].polygons[10], bpy.data.meshes['slab'].polygons[11], bpy.data.meshes['slab'].polygons[12], bpy.data.meshes['slab'].polygons[13], bpy.data.meshes['slab'].polygons[14], bpy.data.meshes['slab'].polygons[15], bpy.data.meshes['slab'].polygons[16], bpy.data.meshes['slab'].polygons[17], bpy.data.meshes['slab'].polygons[18], bpy.data.meshes['slab'].polygons[19], bpy.data.meshes['slab'].polygons[20], bpy.data.meshes['slab'].polygons[21], bpy.data.meshes['slab'].polygons[22], bpy.data.meshes['slab'].polygons[23], bpy.data.meshes['slab'].polygons[24], bpy.data.meshes['slab'].polygons[25], bpy.data.meshes['slab'].polygons[26], bpy.data.meshes['slab'].polygons[27], bpy.data.meshes['slab'].polygons[28], bpy.data.meshes['slab'].polygons[29], bpy.data.meshes['slab'].polygons[30], bpy.data.meshes['slab'].polygons[31], bpy.data.meshes['slab'].polygons[32], bpy.data.meshes['slab'].polygons[33]]

Clearly more than 33 polygons! Any ideas?

I've tried:

  • after remeshing

    bpy.ops.object.origin_set(type='ORIGIN_GEOMETRY') bpy.ops.object.editmode_toggle()

  • after remeshing ob.data.update(calc_edges=True)

  • when reading bpy.ops.object.mode_set(mode='OBJECT')

  • For one thing, you're not going to see the faces of the centers in object mode.. You'll need to be in edit mode to view these. – brasshat Jun 29 '15 at 09:02

After applying the modifier, you can convert the object into a mesh:

How can curves be converted to meshes?

This will "flatten" the results you expected from the modifier into the mesh and you will see the transformed vertices and be able to select them in edit mode.

  • Good deal, I realized that I was applying the mesh in the wrong mode. Fixed with: bpy.ops.object.mode_set(mode='OBJECT'); bpy.ops.object.modifier_apply(apply_as='DATA', modifier="Remesh"); – sirgogo Jun 29 '15 at 17:36
