ShadowMap

new Cesium.ShadowMap(options)
Scene/ShadowMap.js 134

Creates a shadow map from the provided light camera. The normalOffset bias pushes the shadows forward slightly, and may be disabled for applications that require ultra precise shadows.
Name Type Description
options Object An object containing the following properties:
Name Type Default Description
context Context The context in which to create the shadow map.
lightCamera Camera A camera representing the light source.
enabled Boolean true optional Whether the shadow map is enabled.
isPointLight Boolean false optional Whether the light source is a point light. Point light shadows do not use cascades.
pointLightRadius Boolean 100.0 optional Radius of the point light.
cascadesEnabled Boolean true optional Use multiple shadow maps to cover different partitions of the view frustum.
numberOfCascades Number 4 optional The number of cascades to use for the shadow map. Supported values are one and four.
maximumDistance Number 5000.0 optional The maximum distance used for generating cascaded shadows. Lower values improve shadow quality.
size Number 2048 optional The width and height, in pixels, of each shadow map.
softShadows Boolean false optional Whether percentage-closer-filtering is enabled for producing softer shadows.
darkness Number 0.3 optional The shadow darkness.
