Interface EyeDomeLightingEffect

Eye-dome lighting (EDL) is a non-photorealistic lighting model, which helps accentuate the shapes of different objects to improve depth perception, by shading their outlines.

Technically, the lighting model applies a shade to each pixel, based on the depth difference between that pixel and its surrounding pixels. The EDL technique uses 3 properties:

• the window property defines how many surrounding pixels must be taken into account.
• the strength property is a factor to multiply with the shading that is applied to the image. A value between 0 and 1 will soften the shade, a value higher than 1 will harden the shade.
• the color property defines what color the shade will have.

Example

  map.effect.eyeDomeLighting = {
    window: 2,
    strength: 0.5
