Caffe Installation

Please download, build and install the version of caffe introduced here -- we use it for the provided 3D augmentation capabilities.

Modelnet40 Aligned Objects

Modelnet40 aligned objects can be downloaded from the links below. If you use this modified dataset, please also cite the following work from which we borrowed techniques for the auto-alignment:

Questions about Manually-aligned Modelnet40

Hi, thanks for your work. I have some questions about the Manually-aligned Modelnet40 you provided.

Is the data in .off file the aligned object? or it is the same thing as official modelnet40 data and we need to rotate the objects using the .annot file?
Can you provide more information about how to use the .annot file? There are two lines in the .annot file. The first line is the rotation angle around z aixs, isn't it? what does the second line mean? It seems the second line is always 0?
Thank you!

Opening tar file results in one big file

If I open the tar file on WIndows using 7zip or winrar, I find inside one big file. The problem is that the .tar file should renamed to .tar.gz if you want 7zip or winrar to correctly identify the file contents: then all the files and folders appear.

Is the auto-alignment code available?

Hi, may I know if the auto-alignment code was published? It was mentioned that the code will be published soon, but I could not find a link.

Thanks!

How to read the alligned dataset?

Hello,

The provided alligned dataset does not include an extension or any information about parsin it. I use python.

I tried to read it as a binary file with numpy and I received an array with shape (1249415680,).

I know it is an old project hope you are still monitoring it. Thanks for sharing this awesome work guys.
