He also publishes to YouTube where he has clear explanations and high production values that deserve more views.

The PyTorch3D section was genuinely useful for me. I've been doing 2D ML work for a while but hadn't explored 3D deep learning — didn't even know PyTorch3D existed until this tutorial.

What worked well was the progressive complexity. Starting with basic mesh rendering before jumping into differentiable rendering made the concepts click. The voxel-to-mesh conversion examples were particularly clear.

If anything, I'd love to see a follow-up covering point cloud handling, since that seems to be a major use case based on the docs I'm now digging through.

Thanks for writing this — triggered a weekend deep-dive I probably wouldn't have started otherwise.

Cool tutorial :) Any PDF versions?

Thank you, this seems like a very good intro to newcomers! Would be cool if you could continue these series with a few more advanced lessons as well

Very nice, thanks! It’s great to be able to play with viz!

For a deeper tutorial, I highly recommend PyTorch for Deep Learning Professional Certificate on deeplearning.ai — probably one of the best mooc I’ve seen so far

Good post. I think you mixed torch.eye with torch.full though

Looks like a nice resource for the OMSCS Deep Learning class as well.

Tiny suggestion: make the visualization for torch.zeros and torch.ones have the same y-axis limits so the difference is visually separated.

Very nice overview, however just like 30 years ago, neural networks and deep learning stuff is not for me, regardless of the tutorials.

Yet, 2D and 3D graphics feel relatively natural, maybe because at least I can visualize that kind of math.

Did not expect to see a 3D model of Quake 2's grenade launcher in a PyTorch tutorial today.

Are there other similar tutorials like this going into fundamentals of model architectures for example? Something like https://poloclub.github.io/cnn-explainer/ for example

Very well done. I learned something.

Really awesome resource, thanks for posting.

This was quite accessible. If I had to pick one point, I wish there was more "handholding" from gradient to gradient-descent i.e. in the style of the math-focused introduction of the function with one parameter, two parameters etc that was done. It felt a bit of sudden jump from the math to the code. I think the gentle introduction to the math is very valuable here.

This does an honest good job of walking through the beginnings, I would still say understanding/decomposing a decision tree and going through the details and choices /trade offs one makes with how they prepare the tree like binary split or discrete/binning for continuous data. What reducing entropy means, etc. Maybe even start with parametric versus nonparametric modeling pros/cons. You really get to see how probability and statistics is applied in the formulas that eventually will be thrown into a dot function in python.

There is a lot of content on pytorch, which is great and makes a ton of sense since it's used so heavily, where the industry needs a ton of help/support in is really the fundamentals. Nonetheless, great contribution!

Interesting article. It would be really useful if you have added a full article title to the page meta data, so it would get bookmarked with title. I assume one does not require GPU to try out simple examples provided?
