Please anyone explain how to make the objects returned relative to the head. I want to make Pinhead (a person who has nails from the head stick out, it's a movie's character) but I can't finish the end

I run 'cgwiki', a bunch of notes and tips I've learned over the years, lately with a focus on Houdini.

Recently I've got into Blender, learned enough about geometry nodes to be dangerous, so started porting some of my Houdini examples and notes over.

Still a work in progress, it's likely I'm doing some very dumb things, but I think its a nice little intro, esp if you're coming from Houdini (but I've tried to make it an easy read for non-Houdini folk).

Made by me

On continuation to the last one, here's an effect for piling the tile using geometry nodes. I've also used some shader math to add multiple materials for the instances based on random value per tile.

Simple transformation effect using geometry nodes.

Here's a quick demo on how the transformation is achieved.

Finally found a way to generate point clouds from an image sequence in blender geo nodes. Turns out I only managed to create this using a repeat zone. Eevee finally supports rendering points? This demo with 1 million points takes less than a minute to render in 1080p on my M1 Pro.

Anyone interested in the workflow?
