About groundtruth mesh simplification #3

Closed YuanxunLu closed 2 years ago

YuanxunLu commented 2 years ago

Thanks for your impressive work! Here I have a question about the groundtruth mesh generation.

As you illustrated before, the groundtruth ShapeNet mesh can be generated by tools provided by 'occupancy_network'. I found that the entire generation pipeline includes scaling meshes into unit, generating the watertight mesh, and finally simplifying the complex watertight mesh. I follow the steps but I found the last simplification step degrades the mesh quality to some extent (different class suffers the degradation problem at different levels, such as the car class suffers a lot while the chair class is not).

Therefore I wonder whether you apply the simplification processing in your groundtruth meshes?

Thanks again and hope for your feedback!

We didn't apply the simplification step.

We get the ground truth meshes according to the instructions here. The file scripts/dataset_shapenet/build.sh is executed. In this file you can find that the simplification step is not performed.

Hope it helps.
