Ever wondered how badly we're all addicted to buying new GPUs in graphics labs?

![MOTIVATION
Graphical Processing Units (GPUs) are at the core of Computer Graphics research. These chips are critical for rendering images, processing geometric data, and training machine learning models. Yet, the production and disposal of GPUs emits CO2 and results in toxic e-waste [1].
METHOD
We surveyed 888 papers presented at SIGGRAPH (premier conference for computer graphics research), from 2018 to 2024, and systematically gathered GPU models cited in the text.
We then contextualize the hardware reported in papers with publicly available data of consumers’ hardware [2, 3].

'tint' is the shader compiler developed by Chrome to implement #WebGPU. It has a nice command line interface, but so far there is no official build out...
Wait no more! I share here precompiled binaries of tint CLI: github.com/eliemichel/d...

Nice writeup from @mattkeeter.com inspired by our recent work on #LipschitzPruning!
new blog post: "Gradients are the new intervals"
www.mattkeeter.com/blog/2025-05...
If you've got Lipschitz-continuous distance fields, you can use single-point samples to do tricks that normally require interval arithmetic – like hierarchical evaluation and expression simplification!

Starting to track down the usage of #WebGPU resources during a frame in my custom #RenderDoc driver!

Starting to nest events in the #WebGPU driver for #RenderDoc, how do you think I should handle these "WriteBuffer" that occur while encoding a "RenderPass"?
Because chronologically they are submitted before the render pass even though the API call occurs after.

Who would be interested in a version of #RenderDoc that captures and replays calls to the #WebGPU API (rather than calls to the underlying DirectX/Vulkan/Metal API)?
This is an early test that only lists the API calls, but already promissing! Will share when usable.

🏆 So honored that our paper received the Honorable Mention #Award at #SIGGRAPHAsia!
I really like this paper BTW, it is about procedural #SignedDistanceFields, a simple idea to #differentiate them and thus provide #DirectManipulation ✨

Is it me of the activity of the #WebGPU-native spec looks like a #deadline is coming? Just saying...😁
(Also, it makes it hard to follow the pace with the #LearnWebGPU guide, but I'm working on it!)

Corner Pin transform, a.k.a. #perspective transform, is super useful for #imageediting: texture replacement, undistorsion, projections for #videomapping. Corners can be static, or attached to video tracking points, etc.
