Visualize OCNN Weights

[harryseely]

Greetings PS Wang and fellow OCNN users!

I am very interested in visualizing the learned weights (i.e., features) of early OCNN layers. As an example, check out this figure from the Point2Vec paper by Zeid et al. (2024).

I am familiar with octree visualization methods using Open3D discussed in this post, but I am unsure how to visualize OCNN weights using a similar method.

Does anyone have suggestions for the best way to do this?

Thanks,

Harry
