@marketplace.org Heard you mention the job market yesterday and thought I’d share this emerging phenomenon from the perspective of the tech industry. The job market appears to be log jammed by AI both flooding employers with applications and AI processing such applications.

Something everybody should be aware of: planetary roller screws.

As Gradient Control Laboratories has started to consider how to increase our impact, we’ve joined the Speculative Technologies “Brains” accelerator program for feedback on our broader ambitions.

Am thrilled to be with such an inspiring peer group and mentor team.

Looking forward to trying out Adam CAD. Thanks @arnicas.bsky.social !

Agentic Engineering: how AI automata will participate in engineering in 2025

Predictions for engineering software this year and some of the fun to be had wiring it up. To what extent will engineering services left-shift into engineering software?

There’s a new reference implicit kernel in town. The GCL modeling stack was based on libfive, and we’re already in the process of adding Fidget! Congrats @mattkeeter.com

A triply orthogonal system of surfaces from stereographic projection of Hopf coordinates

📝 Am getting started on a paper after some off research, and now have a large directory of poorly named PDFs and a giant bibtex file. Would anyone recommend Zotero or a similar reference manager to get a bit more organized? (I'm an academic late bloomer.)

Ideally, it would work out of Google Drive.

Let's take a look at another application where UGFs are the appropriate setting: chamfers, in particular the constant-width flavor.

(UGFs are a generalization of SDFs considering fields with unit gradient magnitude. www.blakecourter.com/2023/05/18/f...)

Have some old twitter threads that I embed on my blog, and would prefer them hosted here. Let's see how porting one over goes...

I made a computer graphics research starter pack- I most definitely missed lots of people so let me know 😄

@rms80.bsky.social Great to see you here. Continue to use GradientSpace libraries (including Geometry4Sharp) regularly.
Apologies for any name collision in minting Gradient Control Laboratories, something we didn't originally realize. We are just very focused on various gradients of implicits! 😀

Let's take a look at one of the most useful tricks in applied implicit modeling, a trick I like to call the "two body field". For two SDFs or UGFs A and B, let's define the two body field Ξ = (A - B) / (A + B) .

It creates a field that linearly interpolates from -1 at A to +1 at B.

Let me know if you are interested in a CAD system that works like this!

SIGGRAPH Asia (still) coming up! Second paper thread!

"Direct Manipulation of Procedural Implicit Surfaces" where we explore how to create a WYSIWYG editing interface for procedural representations, avoiding awkward sliders!

Greetings everyone! Here's a quick intro to my main project: I study Unit Gradient Fields (UGFs), which are a generalization of Signed Distance Fields (SDFs).

Common operations on SDFs like offset and booleans fail to result in SDFs. These operations, with care, do result in UGFs!

Automatic Medial Axis Computation from SDFs! Here's a fun attempt a first bsky thread.

The medial axis is a structure of equidistance points inside a shape. We can compute it along with SDF Booleans, in a similar spirit to automatic differentiation with dual numbers or error propagation. (1/n)
