Hephaestus
Immersive & 3D
Camera systems, scroll-to-3D synchronisation, performance budgets, and honest mobile degradation.
The forge of living metal. Full experiences that push real-time 3D, scroll-driven storytelling, playable worlds, and high-production WebGL/WebGPU. Study how one hard idea is executed cleanly, and what it costs to run.

- Draw-Call DisciplineHeraclesTreat draw calls as a published budget — one population, one call — so a forge stays honest when the count climbs.
- The Instanced ForgeAchillesFour thousand ingots drawn in a single call, with the draw-call figure published next to the frame time so the cost of the scene is stated rather than implied.
- The Parametric SingularityHeraclesA lightning bolt with no model file — a high-segment cylinder displaced along its own normals by 3D noise every frame, orbited by fourteen shards on an underdamped spring.
- Frame Budget ReceiptHeraclesPublish the millisecond budget next to the work — a receipt that makes optimisation a claim you can audit.
- The Hydro-Prismatic LeviathanHectorA trident where a single transmission material at an index of refraction of 2.42 does all the work, backed by 400 instanced cavitation bubbles it exists to distort.
- The Struck IngotHectorAn object with no vertices — a signed distance field marched per pixel, with the step budget exposed so the exact moment quality is bought back is visible.
- Honest LODHectorLevel-of-detail that drops populations and post, not meaning — a degradation path you can defend on a phone.
- Scroll to StagePenelopeArm a GPU stage only when it enters the viewport, and drive a single uniform from scroll velocity — never from a second RAF.
- Scroll Velocity BusHectorOne RAF writes --scroll-progress and --scroll-velocity; every atmosphere and stage reads the bus without registering listeners.
