Public Attributes
bool	enable = false
	Specifies, if depth bias should be used (default: false).
float	clamp = 0.f
	Specifies the depth bias clamp (default: 0.0).
float	slopeFactor = 0.f
	Specifies the depth bias slope factor (default: 0.0).
float	constantFactor = 0.f
	Specifies the depth bias constant factor (default: 0.0).

Detailed Description

Describes the rasterizer depth bias.

The depth bias can be used to alter the depth value function, i.e. how the values within the depth buffer are distributed. By default, the depth buffer uses an exponential function scale to increase precision for closer objects. The values provided with depthBiasClamp, depthBiasConstantFactor and depthBiasSlopeFactor are used to change the domain clamping, offset and steepness of the depth value distribution.
