Render Technique

Rendering Unity

• Scriptable Render Pipeline (SRP)
• High definition render pipeline (HDRP)
  • for high performance platform
• Universal Render Pipeline (URP)
  • light-weight rendering pipeline, limited light ability.

Minecraft Map Generation

MineCraft world generation, some references:

• MINECRAFT SEED MAP.
• Cubiomes Viewer.
• The browseable map OpenLayers.
• MC C++ MineCraft-One-Week-Challenge.
• MC C++ Voxel Game Mesh Optimizations.

chunk (16*16) generation:

1. terrain shaping (stone/air).
2. fill water.
3. surface layer, replace the top blocks.
4. features & structures.

Terrain shaping:

• Random with different scale: Multiple octaves perlin noises (each octave : double the frequency and double the amplitude).
• Random with Continentalness + Erosion + Peaks & valleys.
  • map : noise -> terrain height
  • build by sampling & spline lines.
• 3d noise perlin noise + height bias.
• caving : density factor.
  • 0/1 : Cheese caves.
  • border : Spaghetti caves.

Surface: Biomes different eco-system bundle. Continentalness + Erosion + Peaks & valleys + Temperature + Humidity –(table map)–> biome type.

Some Tips:

• 16 * 16 * 16 chunks, generate the chunk sides, and only render the visible sides.
  • chunks putting together, hide invisible chunk faces.
  • if block changed, chunk visible faces should be generated.
  • threading chunk generation.
  • skip generation for deep invisible chunks.
• block id encoding, float -> bytes.
• lighted face pre-rendered.

Minecraft World Generation & Nice Modes

• Minecraft Build Generator AI Plugin, nice but not open source.
• Model to Voxels, MagicaVoxel, vengi.
• Distant Horizons, video, extremely beautiful!!
• Earth topology data : NASA topology, Natural Earth, Gebco, Visible Earth.
