chunk-generator Component

The chunk-generator component is an A-Frame component designed to generate terrain chunks dynamically. This component allows for the creation of large, procedurally generated terrains with various customizable parameters.

Schema Properties

• chunkSize:

  • Type: int
  • Default: 50
  • Description: The size of each terrain chunk.

• viewDistance:

  • Type: number
  • Default: 200
  • Description: The distance within which chunks are generated and visible.

• terrainScale:

  • Type: number
  • Default: 100
  • Description: The scale of the terrain features.

• noiseOctaves:

  • Type: int
  • Default: 8
  • Description: The number of octaves used in the noise function for terrain generation.

• noisePersistence:

  • Type: number
  • Default: 0.5
  • Description: The persistence value for the noise function, affecting the amplitude of each octave.

• noiseLacunarity:

  • Type: number
  • Default: 2.0
  • Description: The lacunarity value for the noise function, affecting the frequency of each octave.

• randomSeed:

  • Type: int
  • Default: 0
  • Description: The seed value for random number generation, ensuring reproducible terrain.

• worldOffset:

  • Type: vec2
  • Default: { x: 0, y: 0 }
  • Description: The offset applied to the world coordinates.

• heightScale:

  • Type: number
  • Default: 30.0
  • Description: The scale of the terrain height.

• heightCurve:

  • Type: string
  • Default: '[[0.46,0],[0.48,0.05],[0.5,0.1],[0.6,0.2],[0.7,0.4],[0.8,0.5],[0.85,0.6],[0.9,0.7],[1,1]]'
  • Description: A JSON string representing the height curve, which defines how height values are interpolated.

• terrainRegions:

  • Type: string
  • Default: '[{"name":"WaterDeep","height":0.2,"color":"#0048FF"},{"name":"WaterShallow","height":0.46,"color":"#0087FF"},{"name":"Sand","height":0.5,"color":"#c2b280"},{"name":"Grass1","height":0.6,"color":"#348C31"},{"name":"Mud","height":0.7,"color":"#70543e"},{"name":"Grass2","height":0.8,"color":"#1F6420"},{"name":"Snow","height":0.9,"color":"#FFFFFF"}]'
  • Description: A JSON string defining the different terrain regions, their heights, and colors.

• detailLevel:

  • Type: string
  • Default: '[[100,0],[200,1]]'
  • Description: A JSON string defining the detail levels for the terrain.

• normalizeMethod:

  • Type: string
  • Default: 'global'
  • Description: The method used to normalize the terrain heights.

• applyFalloff:

  • Type: boolean
  • Default: false
  • Description: Whether to apply a falloff effect to the terrain.

• normalizePostFalloff:

  • Type: boolean
  • Default: false
  • Description: Whether to normalize the terrain heights after applying the falloff effect.

• renderMode:

  • Type: string
  • Default: 'mesh'
  • Description: The rendering mode for the terrain (e.g., 'mesh').

• textureFilter:

  • Type: string
  • Default: 'linear'
  • Description: The texture filtering method.

• enablePhysics:

  • Type: boolean
  • Default: false
  • Description: Whether to enable physics for the terrain chunks.

• updateInterval:

  • Type: number
  • Default: 100
  • Description: The interval (in milliseconds) at which the terrain is updated.

Usage

To use the chunk-generator component, add it to an A-Frame entity in your HTML:

<a-entity chunk-generator="chunkSize: 100; viewDistance: 300;"></a-entity>
