When I was first trying to wrap my head around CNNs, I really struggled to visualize how convolution works across multiple channels (the depth dimension). Standard 2D diagrams usually left me confused about what happens to the channels. I ended up building this 3D interactive visualization to make it click. Seeing it in 3D makes it much easier to understand that the filter always spans the entire depth of the input volume at that specific layer. Hopefully, this visual helps someone else who is currently stuck on the same concept: 3D Interactive Viz. submitted by /u/Hackerstreak
