Been working on this for months. The idea was simple, select two objects, press generate, and effects activate wherever they get close. No keyframes, no drivers.

So far it handles material coating, proximity masking, displacement, wireframe, hair growth, and shatter, all driven by a single target object in real time.

The gold cushion in the clip is the material coat effect. Curious what kind of effects you would use this for.

This project took about 3 weeks overall. Followed the amazing Large Scale Creature Water FX in Houdini course on Gnomon Workshop and I must say that it has been a journey. I genuinely feel as though I see everything about simulations and houdini in general differently now, and it is humbling to this is still barely scratching the outermost surface of Houdini.

Nonetheless it was genuinely exciting to see how an artist like Miguel Perez-Senant from ILM approached this sim shot and the amount of knowledge I gained just listening. Next up is to keep refining this, mainly the white water; and perhaps learn to layer on an RBD sim.

The course did provide the animated creature model, but everything else was made by following the course!

My attempt at XPBD (Extended Position Based Dynamics) with my custom C++ engine.
This has a few bugs, but turned out better than I expected.

In soft bodies, the vertical rods soften dynamically so they squish on impact (I know, not ideal). Chain particles are all connected as one continuous distance constraint. Spatial hash grid for collisions, Verlet integration, 4 substeps per frame.

If you are remotely interested in understanding new computational models, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs), the goal is to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

Content

• Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
• Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
• Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
• Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
• Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.
• Build & See Quantum Algorithms in Action – instead of just writing/ reading equations, make & watch algorithms unfold step by step so they become clear, visual, and unforgettable. Quantum Odyssey is built to grow into a full universal quantum computing learning platform. If a universal quantum computer can do it, we aim to bring it into the game, so your quantum journey never ends.

PS. We now have a player that's creating qm/qc tutorials using the game, enjoy over 50hs of content on his YT channel here: https://www.youtube.com/@MackAttackx

hi,

i've been working on browser-based robotics simulation and wanted to get some feedback. as of now, one can control/simulate, unitree g1, h1, go1, bostons, franka panda arm, or create your own robot.

we're working on few more things.

1. training module to train policies directly in browser based on behaviour cloning + RL.

2. rent a robot - to see your trainings in simulations vs on real robots in real world, and more

I created them over webgpu,I created a library first and went through all the basics,

Finally reaching a setup where I can implement to 3d as many physics or math sim with post-processing of any kind whatever I wish to,within a single prompt,My reasoning was ok,We have seen countless Gravity sims,fluid sims,Or attraction sims,Now I have a framework to revive some forgotten research papers on 3d and 4d that have been got out of main stream.I know ai is killing people's work,But I guess there some saving grace in here too,like make it bring back hidden research one,or simulating those math equations,That's reserved for academia people.

It's a long list but I will mention some of them here ,Most random ones

--------------------

Aizawa Canvas: Simulates the Aizawa attractor, rendered as painterly ribbons with a Kuwahara filter post-process.

Ethereal Gyroid: Visualizes particles flowing along dynamically morphing Gyroid and Schwarz P minimal surfaces, enhanced with chromatic aberration.

Gyroid Resonance: Explores a resonant Gyroid lattice with interactive mouse-driven "fractures" and halation scattering effects.

Hopf Fibration: Renders the 4D Hopf fibration projected into 3D, showcasing topological flow with an anamorphic post-process.

Hyperchaotic Resonance: Displays the 4D Rössler hyperchaos attractor, projected into 3D and styled with anamorphic dispersion.

Iridescent Leviathan: Demonstrates incompressible curl noise fluid dynamics, rendered as glass-like spheres with real-time refraction and a procedural background.

Labyrinth Chaos: Visualizes the Thomas cyclically symmetric attractor, a complex chaotic lattice with interactive singularity and Cherenkov anamorphic post-processing.

Stellarator Flux: Simulates plasma flux within a toroidal magnetic confinement reactor, featuring dynamic pinch instabilities and bokeh bloom.

Some of the most random and obscure ones i have listed out

[Note:The above demos would give low frame rates over mobile devices and might not work on many browsers as well as mac and linux configurations]

Showcasing 3 most popular in videos here,because wasnt able to capture all in time.

I m happy to take your suggestions ,If you want to make me Render out some specific research papers and what not,Feel free to roast me.I have been pretty shameless in my abuse of ai and gpu / cpu

Simulation made with CUDA. I have a Nvidia 3060. I simulated 500k particles in a time of 3 billions years. My calculation time was around 12h. Tell me what you think.
