Creative 3D Web & AI Eng. Breaking Browser's Absolute Limits
Cover image for EIDOLON: A museum of lost
EIDOLON: A museum of lost things, rendered in dust (https://jsfiddle.net/Saminsami/vbumrf4o/1) I built this to see if I could make a point-cloud museum that moves with your mouse and still stays smooth at 60 FPS without any framework. No libraries. No build steps. Just Canvas2D and a bunch of tiny floating lights. WHAT I WAS TESTING: I was testing how well I could keep point-cloud rendering alive under constant user motion while keeping the frame rate locked at 60. The system had to handle hundreds of thousands of points updating every frame, and I had to make sure the browser didn’t stutter from garbage collection or event throttling. THE TECHNICAL SIDE: Everything runs in the browser with Canvas2D. No WebGL. No Three.js. No external dependencies. I wrote custom shaders with GLSL to color and animate the point clouds. I hand-tuned the event loop to avoid frame drops during mouse moves, and used requestAnimationFrame with manual frame pacing to stay at 60. Memory is allocated per object and recycled on demand. No global state leaks. No third-party tracking. WHAT I LEARNED: The key was not making the math too tight or too loose. Too tight and the browser would freeze. Too loose and the frame rate would drop. I learned to profile frame times, adjust point update rates based on user velocity, and use a simple debounced event handler to keep mouse movement from overwhelming the system. It runs at 60 on an old laptop, and feels buttery on a mid-tier machine. TRY IT YOURSELF: (https://jsfiddle.net/Saminsami/vbumrf4o/1)Open it in your browser, it's hosted live on my JSFiddle. Move the mouse around. Watch how the clouds react. No lag. No freeze. No framework.😊

Cover image for LONGWAVE: Interactive UV Mineral Cabinet
LONGWAVE: Interactive UV Mineral Cabinet and Fluorescence Archive (https://samincollection2.netlify.app/fluorspar/) I built this speculative mineral cabinet to simulate ultraviolet fluorescence and light-wavelength transitions directly in the browser inside a clean interactive UI. Users can flip the cabinet lamp between 5500K daylight and 365nm longwave UV to watch dull, grey stones instantly catch fire. The system catalogs seven fictional specimens from Verdigrite to Duskbloom mapping out their host lattices, trace metal activators, emission wavelengths (from 416nm cold violet to 640nm rose pink), and seam localities. If you switch the lamp back to daylight, the borrowed photon energy cuts off immediately, while specimens like Sporewort hold a brief half-second phosphorescent linger before going dark. Everything runs on the client side using JavaScript, CSS, and HTML5. The stone visuals, wavelength states, and spectrum plots render locally in the browser without relying on heavy external assets or server calls. The page updates the crystal glow, the three step photon excitation breakdown, and the spectral chart in one pass. I even included a control specimen called Nullstone with zero trace activators. So when someone flips on the UV lamp, it stays completely dark and inert instead of faking a glow. The ragebaiting part was to format and structure out the mineralogy lore and wavelength data so it felt clean and fast. Putting the activator traces, nanometer readings, and locality codes right beside each stone makes it easy to read the numbers while looking at the crystal glow. No distractions. Showing the emission spectrum chart at the bottom also helps visitors see where every specimen sits on the visible band before cutting the lamp.😊

MORDANT: Vault of Unmixable Pigments (https://samincollection2.netlify.app/mordant) Colours that refuse to mix, combed on water in a stone trough. The Mordant Vault guards colours that refuse to blend. Float them on water. Comb them. Never, under any circumstance, stir. I built this project to test Colours that refuse to mix, combed on water in a stone trough. The Mordant Vault guards colours that refuse to blend. Float them on water. Comb them. Never, under any circumstance, stir. The core engineering challenge was sustaining uncompromised 60 FPS rendering using WebGL / GLSL Shaders while handling continuous user interaction without framework overhead. WHAT I WAS TESTING: I focused on two core engineering benchmarks: Precision implementation of shader marbling under continuous interactive user input Sustained 60 FPS render performance and zero-dependency browser execution THE TECHNICAL SIDE: Engineered directly in the browser with WebGL / GLSL Shaders, Canvas2D, Shader marbling. The application runs without third-party frameworks or build-step dependencies, using hardware-accelerated rendering and custom event loops to achieve zero-latency response. Everything executes in the browser using WebGL / GLSL Shaders, Canvas2D, Shader marbling. No third-party frameworks, no heavy runtime bundles, and zero external tracking. WHAT I LEARNED: Balancing the mathematical rigors of shader marbling with tactile browser interaction required tuning event throttling and memory allocation to eliminate all garbage collection stutters. Finding the sweet spot between mathematical precision and frame budget took careful profiling, but the result runs at a steady 60 FPS even on modest hardware. TRY IT YOURSELF: (https://samincollection2.netlify.app/mordant)The live build is deployed on Netlify. Open it in your browser, test the controls, and observe the render response times.
