- :ref:`bool<class_bool>` **get_depth_bias_enabled**\ (\ )

If ``true``, each generated depth value will by offset by some amount. The specific amount is generated per polygon based on the values of :ref:`depth_bias_slope_factor<class_RDPipelineRasterizationState_property_depth_bias_slope_factor>` and :ref:`depth_bias_constant_factor<class_RDPipelineRasterizationState_property_depth_bias_constant_factor>`.

- |void| **set_depth_bias_slope_factor**\ (\ value\: :ref:`float<class_float>`\ )
- :ref:`float<class_float>` **get_depth_bias_slope_factor**\ (\ )

A constant scale applied to the slope of each polygons' depth. Applied before :ref:`depth_bias_constant_factor<class_RDPipelineRasterizationState_property_depth_bias_constant_factor>`.
