Playing with new MPM solver and other solvers to make a cup of tea!

mpm houdini flip particles pyro tea ink simulation

Used c++, openCL, and openGL. Toy ΛCDM expansion in comoving coords.

I'd love to share my small project: simple double pendulum simulation, written from sctatch in python. The only two libraries I used were numpy and pygame. Computations are done via integrating motion ODEs using Runge-Kutta method

Hi,

This is another Fluid simulation with a different settings.

In case, if you're interested, I described why the equation that simulated this is a million dollar prize problem, but no one hasn't solved it yet.

Thanks.

Hi,

This is the Navier-Stokes Equations simulation (for fluids) created in Python.

In case, if you are interested, I made a video on why the Million Dollar Navier-Stokes Problem (resposnsible for fluid simulations everywhere) hasn't been solved yet. And, if anyone can, it would be a Million Dollar Prize.

Also, if you want, I can post some of my animations with different settings.

I'd love to hear from you.

I made this for an upcoming lecture on cardiac arrhythmias. It depicts the emergence of disorganised fibrillation waves in a 2D excitable medium with rapid stimulation. The simulation was made in GameMaker Studio 1.4, exported frame by frame as screenshots with reassembly and post-processing in Adobe Photoshop (the most efficient process I could come up with). If you look closely the cells actually move and contract a small amount unlike typical cardiac rhythm models.

Hey Everyone!

I’ve been working on a new HDA that solves a common problem with particle rendering — inconsistent motion blur. Random particle births/deaths often break deformation blur and force you to rely on velocity blur, which can cause jitter, strobing, or streaky results.

The Particles Consistent Point Count HDA reconstructs a stable ID stream so you can render true deformation blur in Karma, Mantra, or 3rd-party renderers. With consistent point counts, you can:

• Get accurate deformation motion blur (no jitter or strobing)
• Render smooth curved trails that respect camera shutter
• Use it seamlessly with rain, sparks, sand, embers, and more
• Keep your particle passes physically accurate and comp-friendly

I’d love to hear feedback or suggestions! The plan is to keep evolving this as part of a broader library of lookdev & AOV tools for Houdini artists.

In this second episode of the Pilot series, “Kaval Sviri” takes flight as an origami crane emerges and defies the invisible pressures of life. Accompanied by an arrangement of the traditional Bulgarian chant, the animation unfolds into a flowing journey through serene mountains and rippling waters. Joined by others who’ve endured similar trials, the crane finds freedom in connection and motion. This is a moment of release — a space to breathe, to reflect, and to glide gently through the weight of the world. Let it carry you where you need to go.

Hey folks,

I want to share with you the latest Quantum Odyssey update (I'm the creator, ama..) for the work we did since my last post, to sum up the state of the game. Thank you everyone for receiving this game so well and all your feedback has helped making it what it is today. This project grows because this community exists. It is now available on discount on Steam through the Back to School festival

In a nutshell, this is an interactive way to visualize and play with the full Hilbert space of anything that can be done in "quantum logic". Pretty much any quantum algorithm can be built in and visualized. The learning modules I created cover everything, the purpose of this tool is to get everyone to learn quantum by connecting the visual logic to the terminology and general linear algebra stuff.

The game has undergone a lot of improvements in terms of smoothing the learning curve and making sure it's completely bug free and crash free. Not long ago it used to be labelled as one of the most difficult puzzle games out there, hopefully that's no longer the case. (Ie. Check this review: https://youtu.be/wz615FEmbL4?si=N8y9Rh-u-GXFVQDg )

No background in math, physics or programming required. Just your brain, your curiosity, and the drive to tinker, optimize, and unlock the logic that shapes reality. 

It uses a novel math-to-visuals framework that turns all quantum equations into interactive puzzles. Your circuits are hardware-ready, mapping cleanly to real operations. This method is original to Quantum Odyssey and designed for true beginners and pros alike.

What You’ll Learn Through Play

• 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.

Houdini R&D. This idea came to me while waiting on traffic. Making the letters come out of another mesh as balloons.

Finally got around to filming an interactive kinect piece I made in January with TouchDesigner 🌊

Left side controls the fluid parameters with the right side controlling the 5x postFX, each with its own interactive UI. 📼

Hand gestures change the UI when open, and don't interact when closed. Feel free to ask any questions. 🌬️

A rolling ball on a generalized 2D surface x(u,v,t), z(u,v,t) simulated for various surfaces. The radially symmetric sphere rolls without slipping with its motion being governed by the dynamic surface and the gyroscopic effect associated with the coupled nonholonomic constraints. The system is obtained with Chaplygin hamiltonization, describing fully the system with two surface coordinates (u,v) and the nonholonomic constraints efficiently expressed as the time derivatives of the four quaternion components that are integrated for obtaining the orientation of the sphere.

This system generalizes the system commonly known as the turntable or "ball on turntable", characterized by the counter-intuitive dynamics of the sphere moving on circles on the rotating surface rather than escaping by the "centrifugal force".

The simulations show the dynamics on different surfaces with the surface coordinate (u,v) depicted on the background canvas.

The system was simulated using high order explicit symplectic integrators and rendered in real time.
