Hi!

Can you please provide pre-processed mesh templates used?

Hi,
Please find the models here.

Also, if you can access the mean_shape.mat file under cachedir/shapenet/<category> it also has the corresponding verts and faces which you can dump as an obj.

Thanks a lot, Nilesh! That was fast :)

Hi Nilesh,

I am trying to get a template mesh for another object. Simply running mesh deform doesn't seem to generate templates like the ones you shared. I realized reading from your ReadMe I need to complete the following 2, 3, 4 steps before doing mesh deform. Is this correct?

1. Have a model of the category as an obj file.
2. Convert the model to tsdf field.
3. Run Marching cubes to get on model
4. Model clean + close holes a. Merge Close vertices b. Quadratic Simplication c. Remove non-manifold edges
5. Mesh-deform to create a parametrized mapping

How did you do 2,3,4? Do you have a code for it?
I see here marching_cubes.py mentioned in the following line and I cannot locate marching_cubes.py file in the repo:

csm/csm/preprocess/parameterize/normalize/normalize_online_model.py

Line 44 in 5923517

print("python marching_cubes.py <in_file.obj> <out_file.obj>")

Thanks for your help!

Best,
Anand

Hi Anand,

Step 2 can be done using this code. Alternately you can also run binvox on the mesh obj file, and then using that voxel volume as input to marching cubes.

Step 3 can be done using marching cubes from scipy

Step 4 completed in meshlab.
