Question about the affordance label

[zdchan]

Hi,

Thanks for your great dataset. But may I ask how can I find the affordance label? It seems every object looks the same inside MeshLab regardless of the affordance. And the object_mesh vertexes look the same without any annotation about affordance. E.g., jar 4118 looks like this

I noticed every vertex is followed by 5 or 7. Does this means the affordance label?

Best,
Hui

Yup, the fourth column in ‘object_mesh’ indicates the affordance label for every point of the object. Here’s a breakdown of the relationships: 1: Handle-grasp, 3: Press, 4: Lift, 5: Wrap-grasp, 6: Twist, 7: Support, 8: Pull, and 9: Lever.

Hi,

Thanks for the answer. So the object_mesh in different json files for different hand poses and affordance categories of the same object are the same? E.g., all the json filea under bottle/3415 have the same object_mesh? And each point of the object mesh belongs to a single affordance label?

Yes, that's right.

Do you know how to visualize the mesh with different colors assigned to different affordance labels, just as your rendered images here?

Another question is that, what does affordance label 0 mean?

Thanks a lot!

I guess 0 means this point doesn't join the interaction.
