The magnitude of the tensor should be(12311,32,32,32).
but got (5,32,32,32),and the h5 file has size 1.6GB.
its wired...
do you know why?

when i use the command
../bin/voxelize occ ../examples/input ../examples/output.h5
i meet this problem.
terminate called after throwing an instance of 'std::invalid_argument'
what(): stoi
Aborted (core dumped)

I am currently looking for a fast CPU based voxelizer for mesh files and wondering, whether your project might fit my needs. I want to start from STL files and be able to get the voxelized version as a numpy array for further processing. Do you think that would be worth the required effort or are there better alternatives?

Hi!

Thank you for your perfect work. I have a question that is there any way to turn the voxel into a triangle mesh?

Thank you very much.

../bin/voxelize occ ../examples/input ../examples/output.h5
i found that when filename like "a.off",failed ,invaild augument..............
It looks like it only supports naming files with Numbers

Whatever you put in, it's going to produce a cube.the filled.h5 file tensor is Most of them are 1.(>99%)

Hello!

First, thank you for your awesome job!

Currently I'm working on the auto-encoders of 3D voxels. As you have said,

Note that these are not "filled"; meaning that only the mesh surfaces are voxelized.

many datasets provide voxels that contain only the surfaces, leaving the inner part hollow. This make it very difficult for auto-encoders to catch the surfaces, since the surfaces are only 1-grid-thick. I hope some tools can help me to fill them automatically.

My question is that, is filling the inner part of a water-tight voxel still an open-question? Is there any good idea to do it automatically?

Thanks.

Hi,

is there any plan on adding color to the voxels? Do you know of any library that generates voxels with color info?

thanks!

hello, i want to use PartNet, the file is .obj. could you please tell me how to translate it to .off?
thanks very much

I am receiving errors compiling without setting any extra C or CXX flags. Any idea how to get around this?

(Compiling with the latest unstable/stable 3.3.4 version of Eigen. Not sure if this is an Eigen issue or C++ issue).

Thanks!

When building the repo, I encountered several errors with the following error message:

‘class H5::FileIException’ has no member named ‘printError’; did you mean ‘printErrorStack’?

After tracing the code, I found that in read_hd5.cpp and main.cpp, there are calls to the printError function, which turns out should be printErrorStack. I fixed this locally and was able to build the executable. Maybe you want to update the repo to fix this issue.

Great thanks for sharing your code and it does help me a lot.
I follow the readme. first, scale off, and then generate. But it seems that it works really slow when generating 256^3 voxels (10 files more than 30min) does it work correctly? If not, what could be the problem?
Looking forward to your reply.

Hi @davidstutz ,

I am using this mesh-voxelization script to generate SDF volume with the ShapeNet dataset.
The model I tested is a watertight sofa model, but the result shows there is no interior value generated.
The value of the num_intersect variable is always even number.
Could you give me some suggestions or help in solving this weird situation?
Thank you very much for considering this matter.

The model I am using for testing is
ShapeNetCore.v2\ 04256520 \ 1037fd31d12178d396f164a988ef37cc \ models \ model_normalized.obj
