Which dataset type to use with custom dataset #33

Closed jnyjxn closed 4 years ago

jnyjxn commented 4 years ago

Hello and thank you for this intriguing work!

I want to use my own custom dataset with this and just want to better understand the use cases for the different dataset types in the manifest -> ["data"]["dataset"].

I have a file structure like this:

Dataset -> { Data_Item_1...Data_Item_N } -> { [Images x n], model.binvox, points.npz }

from which I want to recover a mesh.

Should I use the ShapeNet dataset type or an Images dataset?

Many thanks for your insight!

You should usually use the Shapes3D dataset type. The other datasets are only used for inference when you have already trained your model.

Hi @jnyjxn and @LMescheder thanks a lot for the custom dataset creation part debugging comments, it helped me a lot. I want to test my custom dataset and I created my 3D files .binvox, pointcloud.npz and point.npz, but I am not sure about images of the 3D data. What is the format of the images of the training for single image reconstruction (resnet18)? npz or png? For each 3D off watertight mesh I have one single png image. There is a get_r2n2_cameras.py but I could not clearly understand what is happening inside. Any help would be greatly appreciated. Thanks in advance

Many thanks for your insight! Halo,my friend.could you tell me how to generate the "{ [Images x n], model.binvox, points.npz }" files your own dataset.I have the difficulty with creating it.I could use some assistance, if you have a moment.
