Vivarium — Asset Pipeline

Procedural & generative game-asset pipelines, all running locally on an ASUS Ascent GX10 (NVIDIA GB10, CUDA 13).

Character flow: text prompt → Z-Image-Turbo (2D sprite) → Hunyuan3D DiT (geometry) → decimate + UV + PBR paint → textured GLB. Buildings are AI-generated 2.5D sprites composited into an isometric world.

Model Benchmarks

Arcane World Prototype

AI-generated ground texture composed into an iso world. Z-Image vs SANA-Sprint vs Bonsai side-by-side.

Speed & Quality Benchmarks

Z-Image-Turbo vs SANA-Sprint vs Bonsai ternary-4B — resolution sweeps, step counts, isometric buildings and wizard characters. Full latency and VRAM tables.

Characters — 3D

3D Character Matrix

5 reconstruction-friendly styles × 4 themes, reconstructed to textured 3D via Hunyuan 2.1. Click any tile to spin it.

Arcane Characters (3D)

Arcane wizard cast (archmage, witch, necromancer, apprentice) reconstructed to textured 3D to match the arcane world — base Hunyuan track. Spin them.

Arcane Characters (new pipeline)

Full-body cast on the validated pipeline: Z-Image sprites, solid props (clean witch hands), no UltraShape, hi-res paint. Spin them.

Wizard 3D Comparison

Same chibi wizard reconstructed three ways — Hunyuan 2.1 vs InstantMesh vs TripoSR — with the full pipeline overlay.

Arcane World Scene (real-time)

Real-time 3D: arcane wizards (base cast) on the AI ground with building billboards. Fixed iso view — click a wizard to spin it.

Arcane World Scene (new-pipeline cast)

Same real-time world populated with the new full-body cast — Z-Image, solid props, hi-res paint. Compare against the base scene.

Procedural Buildings

Token-driven 3D building meshes (7 types × 3 levels) — deterministic, no ML. Level I/II/III switcher.

Sprite-to-3D Generator Comparison

Z-Image-Turbo · SANA-Sprint · Bonsai — same prompt and seed, only the 2D generator differs. Benchmarks time and quality across three generators feeding Hunyuan3D-2.1.

Characters — 2D source art

2D Style Explorer

192-sprite sweep — 8 art styles × 4 themes × 6 subjects — to find an art direction. Filter by style/theme.

Wizard Chibi Sprites

The original 8 chibi-clay wizard characters — the seed set that drove the 3D pipeline.

Explored — not adopted

UltraShape Refinement

UltraShape 1.0 geometry refinement (~8× faces) on top of Hunyuan. Verdict: no meaningful gain — the extra detail washes out once textured at game scale, for ~10 min/character extra. Kept as reference.

Face-Quality Investigation

Every lever tested — geometry refine, input upscale, hi-res paint, portrait framing. Verdict: face quality is bounded by source-sprite face pixels; portrait framing is the only big win.

Portrait Reconstructions (3D)

Spin the apprentice reconstructions side by side — Z-Image vs SANA-Sprint portrait busts + the full-body model. Pipeline & benchmark panel included.

Each gallery has an ⓘ Prompts & Benchmarks panel documenting its pipeline, prompts, and timings. · wizard_viewer.html (InstantMesh-only) was retired — superseded by the Wizard 3D Comparison.
