API Reference > imodeljs-common > DisplayStyles > AmbientOcclusion > AmbientOcclusion.Settings > bias bias Readonly bias: number If defined, represents an angle in radians. If the dot product between the normal of the sample and the vector to the camera is less than this value, sampling stops in the current direction. This is used to remove shadows from near planar edges. If undefined, the bias defaults to 0.25. Defined in core/common/src/AmbientOcclusion.ts Line 46 Last Updated: 12 June, 2024
