Tracking issue: Graphics

Entities

• Parse model data
• Render models
• Animations
• Armor (not sure how it works)

Block Colors & Textures

• Texture atlas
• Fix biome-based colors (grass, leaves, foliage)
• Support animated block textures (fire, lava, water)

Block Geometry & Models

• Simple cube rendering (baseline)
• Parse & render JSON block models (rotations currently broken)
• Chunk mesh + render (no live updates yet)
• Block rotations (stairs, slabs, doors, etc.) assigned to @Kumpelinus
• Handle connected textures (glass panes, etc.)
• Live chunk updates (re-mesh on chunk/block changes)

Lighting & Shading

• Lighting
• Smooth lighting
• Fancy shadows

Transparency & Special Rendering

• Transparent blocks (glass, water, ice) (work in progress)
• Semi-transparent overlays (grass side tint)
• Fluid rendering (flowing water/lava)
• Special cases (beacons, portals, banners)

Particles

• Block breaking particles
• Fire/smoke particles
• Entity-based particles (crit hits, potion effects)
• Weather effects (rain, snow)

Camera & UI

• Free-fly camera (WASD + up/down)
• First-person / third-person views
• Debug HUD overlays (coords, FPS, etc.)

HUD Tracking

• Add egui integration for HUD rendering

Performance & Assets

• Asset extraction pipeline (codegen/genassets.py)
• Correct face culling shapes/algorithm (current culling causes some faces to disappear)
• Instancing
• Mesh shaders
