Features
Features : (Language : C#, Unity 5)
-
Voxel Terrain : Algorithms
-
- Marching Cubes : A smooth and fast terrain algorithm
-
Terrain Octree based LOD
-
Hexagonal : An unique terrain hexagonal
-
Cubic : A simple cubic terrain like minecraft or cubeworld
-
2D Tiles : (Terraria Like)
-
Surface Nets : Like marching cubes, but less detailed
-
TerrainEngine contains a robust core that allow to implement any algorithm easily.
TerrainEngine core is made for real-time terrain deformation and it can handle a lot of players/objects deforming the terrain without any FPS drop -
Multi-threading :
-
Action Framework : Dispatch actions over multiple frame for keep a constant FPS
-
Multi-threading Framework : Dispatch actions over all your CPU core to improve performance
-
Thread-safe PoolManager : Pooling system that will store and reuse all objects to improve performance. (Objects and GameObjects).This system contains also an Automatic Smart memory deallocation. Objects will be deleted automatically if needed.
-
Terrain Systems : (Processors)
-
Grass : Grass system that will generate plants into the terrain. This system can generate all type of plants : Ground,Climbing,Weeds,Underwater, Aquatic. Plants can be added to the ground or to the top (caves) of terrain. It’s possible to use a texture and a mesh as grass, so there is no limit to the possibility. Batching is multi-threaded.
-
GameObjects : This processor will add Gameobjects to the terrain. It’s used for Trees/Rocks/Particles/etc… It contains a multi-threaded LOD system that can switch over different objects depending of the camera distance. It contains also a function to automaticaly generate an LOD plane/crossplane from any object for use it when camera is at a certain distance. LOD objects can be batched to reduce drawcalls.
-
Details : This system is used for add objects to the terrain that can be combined. For example for small rocks,plants,roots etc. This processor combine objects to reduce the Drawcalls so it allow to have a lot of details to the terrain with a small fps impact. Batching is multi-threaded.
-
GameObjects Scripts : A simple and easy scripting system is provided for gameobjects, it’s possible to handle when terrain is modified and play effects like if the voxel is removed under a tree, the tree fall.
-
Construction Kit : A system for create building easily. It allow users to create multiple voxel form and place them to the terrain as object. This system interract with fluids so it’s possible to create bridge, barges etc… . [TerrainEngine] Free Official Construction Kit (7DTD Like) - Community Showcases - Unity Discussions
-
Voxels Physics : Flying voxels falls. It’s possible to build and destroy everything
-
Unity Terrain Converter : Convert your Unity Terrain to voxel terrain. Keep Grass/Details/Trees
-
Terrain Utilities :
-
Raycasting : It’s possible to use raycast directly over voxels. It’s thread-safe so it’s possible to use voxel raycasting into multiple thread for increase your game performance.
-
Occlusion Culling : This system disable invisible chunks. It useful when the camera is in cave, all mountains/invisible terrain are disabled so performance is increased.
-
Dynamic Terrain Combiner : This system combine chunks using the same material to reduce the drawcalls and improve performance. It works in tandem with occlusion culling.
-
PathFinding : A simple and fast PathFinding system that will return a list of points to traversal to go through a point A to a point B. This system can manage if the path is for Ground,Fly,Aquatic,etc units.
-
Optimized Zlib : Custom Zlib framework for compression. Used for save/load terrains.
-
Optimized LibNoise : 40% more performant libnoise library than all existing solution for procedural worlds.
-
Fluids :
-
- Real-time fluids : Add water or lava to your game, fluids will flow in realtime without any fps impact.
-
Fluids Effects : With a simple script it’s possible to handle when a fluid flow and add effects like particles, sounds etc.
-
Fluids are Multi-threaded
-
You can define a lot of params like evaporation, visquosity, etc
-
Fluids combiner : A combiner that will batch all fluids mesh, only few drawcalls for the entire terrain.
-
Waterfalls : Add waterfalls and rivers to your game.
-
Procedural : (Infinite Terrain)
-
- Custom LibNoise Framework : A modified LibNoise framework that can manage noises and biomes
-
HeightMap Processor : A complete system to generate heightmap from noises. It contains a complete GUI and inspector for create and manages noises and biomes.
-
Biomes : It’s possible to create biomes in differents scenes and blend them together. For each biome you can add objects (grass,trees,rocks,etc) and define when and where they can be added to the terrain : depending of the altitude, depth, noise, underground, etc…
Everything is drag and drop based, you can create a world in few minutes with a lot of details like climbing plants, Trees with LOD, waterfalls,etc… -
Procedural Caves
-
Procedural Volcanoes
-
Procedural Floating Islands
-
Procedural Rivers and Waterfalls
-
Procedural Canyons
-
Procedural Fantasy world
-
Shaders :
-
- Tri-Planar (PBR): TerrainEngine use an advanced distance based tri-planar shader that allow to have a lot of details.
-
Multi-player :
-
- Server : TerrainEngine architecture is client/server based. When you play in local, the game start an internal server and communicate with it.
The server generate and send terrains to players.
- Server : TerrainEngine architecture is client/server based. When you play in local, the game start an internal server and communicate with it.
-
This internal server can be used for create a multi-player server easily :
TerrainWorldServer Server = new TerrainWorldServer();
Server.Start(); -
This internal server also can be exported to an external project, the complete generation system doesn’t use any unity classes so it can be compiled directly into another project.
-
TerrainEngine architecture is ultra generic, it’s possible to use all systems like PathFinding or Raycasting server or client side without any modification
-
A Simple network server (TCP) is provided as example. Terrain deformation are sync
-
The server can interract with GameObject Scripting system. It’s possible to active or disable a script directly from the server. (Example : A player hit a tree, you can active the TreeFall script for all players around)
-
Demos Scenes :
-
- 20+ scenes : The solution contains more than 20 scenes and examples game using all Type of Terrain and game type. All youtube video are made from demos scenes.
