#physics simulation

An early prototype from the creator of Juice Galaxy.

During the past week I finally got visualization working for hair simulations. Here's a screenshot I captured today, from a real-time simulation of 9,999 strands, each containing 25 points, at 360 iterations per second. Most of the computation was offloaded to my laptop's GPU.

Now as I study it closely, I'm dissatisfied with the flat-shaded meshes use to visualize the colliders. Always something to improve!

Software used: Linux Mint v22.3, jdk-17.0.15+6, Vulkan SDK v1.4.341.1, LWJGL v3.4.1, Jolt JNI v4.1.0, Sport-Jolt v1.3.0, and Jolt Physics v5.5.0+ (custom-built using clang)

Cem Yuksel created the hair model: https://www.cemyuksel.com/research/hairmodels/

Murat Afshar provided the collider meshes. GIMP v2.10.36 was used to crop the captured image.

A shout out to Jorrit Rouwe @jrouwe.bsky.social for publishing Jolt Physics (on which Jolt JNI is based) and the "HairTest.cpp" sample code from which my (Java) app is derived.

"A qubit made from photons lives in the polarization property of light. This is depicted here as individual glowing wavelets. Coated pieces of glass, such as the cube shown in the video, can separate out different polarization states of light. Other elements can switch the polarization from one state (vertical) to the other (horizontal). Photon qubits can also live in other properties, such as color." (Caption via The Quantum Atlas)

One of a series of videos I made for UMD's Quantum Atlas:

I'll soon be available for more work like this, kindly contact me via:

Although my work tends to be primarily physics-related — from subatomic to cosmic scales — I'm also interested in other fields e.g. Long COVID research & advocacy.
