data texture controls

Detail map or textures control uses the value of the heightmap to select and combine the textures (or colors) to apply on the object. The control is done on the current height or slope of each point of the object.

Texture Control

The texture control is a control that assign a detail texture depending on the height or the slope of the current point of the object.

Parameters

• type: textures
• texture|height|slope|biome: List of control entries, see below

Entries

texture entry

• texture name : Name of the texture in the texture dictionary

height entry

• height: Height of the top of the layer, optional, default value is 0
• height-units: Units of the height parameter, optional, default value is Metres.
• blend: Blend factor with the previous layer, optional, default value is 0.
• entry: Texture control entry for the layer.

slope entry

• slope: Maximum slope of the layer in degrees, optional, default value is 0
• blend: Blend factor with the previous layer, optional, default value is 0.
• entry: Texture control entry for the layer.

Example

control:
  slope:
    - entry: dirt
    - entry:
        height:
          - entry: soil
            height: -2000
            blend: 10
          - entry: grass
            height: 0
            blend: 10
          - entry: rock
            height: 1000
            blend: 10
          - entry: snow
            height: 3000
        angle: 5
        blend: 5
    - entry: rock
      angle: 35
      blend: 10

Colormap Control

The colormap control is a simple control that assign a color for a height layer, color between each layer is interpolated linearly.

Parameters

• type: colormap
• entries: List of colormap layer, mandatory
• percentage: true if the height parameter in the layers is a percentage, false if it's an actual height, optional, default value is false.
• float: true if the color components are float color (range between 0 and 1), false if the color components are integer (range between 0 and 255). Optional, default value is false

Entries

• height: Height of the top of the layer, mandatory.
• height-units: .Units of the height, optional, default value is Metres
• bottom: Color of the bottom of the layer, optional, default value is top value of the previous layer.
• top: Color of the top of the layer, mandatory.

Example

control:
  type: colormap
  percentage: true
  entries:
    - height: 0
      bottom: [0, 0, 0] #black
      top: [255, 120, 255] #Purple
    - height: .2
      top: [120, 120, 255] #Blue
    - height: .4
      top: [120, 255, 255] #Aqua
    - height: .6
      top: [120, 255, 1201] #Green
    - height: .7
      top: [255, 255, 120] #Yellow
    - height: .9
      top: [255, 120, 120] #Red
    - height: 1.0
      top: [255, 255, 255] #White
    - height: 1.0
      top: [0, 0, 0] #black
