C# Class LibNoise.Modifier.Select

Noise module that outputs the value selected from one of two source modules chosen by the output value from a control module. - LeftModule outputs a value. - RightModule outputs a value. - ControlModule is known as the control module. The control module determines the value to select. If the output value from the control module is within a range of values known as the selection range, this noise module outputs the value from the RightModule. Otherwise, this noise module outputs the value from the LeftModule By default, there is an abrupt transition between the output values from the two source modules at the selection-range boundary. To smooth the transition, pass a non-zero value to the EdgeFalloff method. Higher values result in a smoother transition.

_edgeFalloff protected_oe property

The falloff value is the width of the edge transition at either edge of the selection range. By default, there is an abrupt transition between the values from the two source modules at the boundaries of the selection range. For example, if the selection range is 0.5 to 0.8, and the edge falloff value is 0.1, then the GetValue() method outputs: - the output value from the source module with an index value of 0 if the output value from the control module is less than 0.4 ( = 0.5 - 0.1). - a linear blend between the two output values from the two source modules if the output value from the control module is between 0.4 ( = 0.5 - 0.1) and 0.6 ( = 0.5 + 0.1). - the output value from the source module with an index value of 1 if the output value from the control module is between 0.6 ( = 0.5 + 0.1) and 0.7 ( = 0.8 - 0.1). - a linear blend between the output values from the two source modules if the output value from the control module is between 0.7 ( = 0.8 - 0.1 ) and 0.9 ( = 0.8 + 0.1). - the output value from the source module with an index value of 0 if the output value from the control module is greater than 0.9 ( = 0.8 + 0.1).
