15. Planet Nomads
Alpha Planet
- Sphere with 120 km in diameter
- 190 kms of pole-to-pole
adventure
- Multiple biomes
- Procedurally generated terrain
with 3D noises
- Voxelized and fully destructible

16. Sandy Voxel Terrain Engine
(C++ Library in Unity)
• Our own = complete control
Great performance due to:
C++
Direct multi-threading
Custom memory management
Communication with Unity through action pools
3D noises interpolated on a sphere
Voxelization - Marching Cubes algorithm with caching
LOD System - chunks ranging from 16 m to 128 km
16x16x16 voxels in a chunk
Minimum voxel size = 1 m
Persistent worlds with quick save/load and real-time generation

19. How Planets Are Generated
Any Planet You
Like
Layout of All Biomes
Selection of
humidity and
temperature range

20. The Worlds Are Persistent
- Every hole you dig
- Every block you place
- Where you park your car
All saved in an SQLite Database
Real-time world generation + game Saving/Loading

21. Gravity
Unity Vector3.Up NOT OK! OK!

22. Wheel Physics
- Unity physics is the basis
- Unity wheel collider only bottom
- Custom wheel collider for
“a climbing wheel”
- 3 raycasts per frame (120°)
rotating every frame
whole wheel detection in 2-6 frames

25. PBR Shaders Are Great

26. Why Use Unity Then?
- 6 people, 2 years of development, grand game
- Saved time
- More saved time with editors for designers
- Nice things - PBR shaders, camera effects, easy-to-use plugins, help
from a big partner
- Best of both
