New at #SIGGRAPH2025:. Can we make Perlin Noise stretch along some underlying vector field? Well it turns out it's possible with two simple additions to the original method! No need for advection or convolutions. Find the paper and implementations here:.

RT @FabriceNEYRET: @TearsOfJake If people want to play with the parameters, I adapted Jake's 2D version to add a GUI. ;-)..

Anyways if you're interested in coming to the talk it'll be presented at SIGGRAPH 2025 on Sunday August 10th, at the "Character Animation Make Some Noise" session at 9:00 AM. Hope to see you there!!.

The github repo also includes links to some shader toy demos, so check those out! Here's one for noise on an SDF surface :).

The least obvious part of all of this is how to construct that metric tensor G from a given vector, but it turns out it's super straight forward. The attached example shows how to do so for a 3D metric tensor. In our paper we outline specific bounds for the sizing of this metric.

Just to elucidate the idea a bit more, on the left we have the original perlin noise algorithm, and on the right we have the steerable version, with the changes underlined in red. We simply add a second set of weights, and incorporate our metric into the original dot product step

"Harlan Crow built the most classically beautiful and awesome US place." Yeah man the most classically beautiful place in America is a business center in Dallas!!!. Why have beautiful natural vistas when we could instead pilfer them for business parks! You're a genius!!.
@Anc_Aesthetics Harlan Crow built the most classically beautiful and awesome US place at Old Parkland. A patriot & legend. Mike Lee’s a pro-liberty guy who loves our country. We sometimes disagree but I admire him. Western states should NOT be mostly Federal-owned. Some private land is great.

I got to tour ILMs mocap stage this past week and the fidelity difference between this and what modern mocap setups generate is astounding. This looks like absolute dog water comparatively. Not to say that this type of tool shouldn't be sought after but this in no way cooks.
🔥 Motion capture is cooked. Remember those complex vests that were needed to create Gollum? RIP to that. Unreal Engine created real-time EVERYTHING: multi-user, markerless motion capture for face, body, and hands all at once. Like magic 🪄.

Every sentence in this press release is an assault on my senses. Whether it's the bold lie that this won't just be used as an apparatus for spying on civilians or the weird conflation of democracy and free markets. It's just miserable stuff.

classic example of it. You even got the incredible defocus during the zoom. And maybe this isn't wiggle and is instead something from blender or C4D, but god damn it looks like wiggle!.
The photo recently revealed by #Elizondo is similar to this #UFO filmed in China on August 26, 2020 #uap #ovni

I love that all fake videos use the same terrible camera shake. After Effects's wiggle expression has done irreparable harm to conspiracy communities.

This inspires me to strive to be better. I'm almost 30 and felt like I was losing my chance to make an impact in the world. Horse Race Tests shows that anyone no matter how old can create works of art that move society forward.

Being obsessive about your passion is cool! Do things for the money if you have to, but if you can avoid it, do it for the love of the game.

This describes like 75% of all professional artists I've worked with, minus the important or lucrative part.
my heart doctor is this dude who has been studying heart electricity for pretty much his whole adult life, he is absolutely obsessed and i feel like it easily could have been something like tekken or collecting JAV but he just got kinda lucky that it was important and lucrative.
