@SebAaltonen @FuchsiaBlu Why would you use AI to generate props if you can just use the props in the training set?

A few months ago I started writing a Photoshop alternative built on a node graph. Mac and Windows, native C++, 75 nodes. Every operation is non-destructive. Paint, masks, warps, the whole toolset. Nothing bakes.

ArcBrush 1.0 is live today!

Very interesting post on hair geometry, linear swept spheres, and voxel approximations

This is one of the best articles on this topic:

Penetration-free for free, you need OGC.
I released the code of our SIGGRAPH 2025 paper: Offset Geometric Contact, where we made real-time, penetration free simulation possible, with @JerryHsu32 @zihengliu @milesmacklin @YinYang24414350 @cem_yuksel

Happy Friday 13th! My first rigging post is live! This is hopefully the beginning of a series of many posts tackling commonly asked questions in rigging. What other questions would you like to see answered? Let me know what you think! #rigtip #gamedev https://t.co/7plrP5Fe7S

Do pages on @internetarchive expire?
I can't load my favourite Geomerics paper anymore 😢

Luckily I found a local copy, so in case you'll need, here's a reupload: https://t.co/fNxdfr452Q

We present Neural Riemannian Motion Fields (NRMF) as a promising paradigm for generative modeling of articulated motion. Unlike various diffusion based models, NRMF is useful both in generation and in deployment as a prior across tasks: https://t.co/4zxB23TOqh. #CVPR #AI #CVML👇

@dcellgames Wow this is is different from the trailer 2 on youtube but I love it more!

[Duarte David @_DuarteDavid]

@Michael_Moroz_ Oh, got it! Thanks :)

[Duarte David @_DuarteDavid]

@Michael_Moroz_ Sorry for the extremely basic question, but how would this be any different from the PIC/FLIP family of methods? Those methods also keep track of particles positions and velocities, but solve for the pressure/force by splatting the particles on the grid.

@playeroldskool Many people can't have properly calibrated screens or the exact same ambient lighting conditions. Which is why in-game brightness options are a must!
Also, the original TRAOD had gamma options on PC, which I always felt like was a must.

You cannot get physically-based rendering right without understanding radiometry. My new blog post explains it all, relying on familiar concepts from rendering algorithms as much as possible.
Part 2 will come next week.

O Chega marcou para hoje um debate sobre “segurança em Portugal”. Vamos aos factos? Em 2023 houve -56% (-864 casos) de crimes contra a vida do que em 2012, quando o PSD governava com o apoio de André Ventura. (1/7)

🔥 Replace your Marching Cubes code with our Occupancy-Based Dual Contouring to reveal the "real" shape from either a signed distance function or an occupancy function. No neural networks involved.

I’ll present our paper “Trust-Region Eigenvalue Filtering for Projected Newton” at #SIGGRAPHAsia2024.

Come check out our talk on Friday at 9-10:10 am! :)

ハイトマップから作るminmax mipmapと精度保証に使われるアフィン演算を組み合わせて、オンザフライなBVH構築によりテクセル粒度のdisplacementを実現。ベースは平面じゃなくてもOK。

Our biomechanical shoulder model now has full contact geometry, so the arm must navigate around the torso to reach behind...

A major blocker to free and open source multimedia is @isostandards.

ISO standards are behind an expensive paywall, making them impossible to access for volunteer developers in FFmpeg, or anyone wanting to learn about multimedia technology
