C# Class LibNoise.Renderer.GradientColor

Defines a color gradient. A color gradient is a list of gradually-changing colors. A color gradient is defined by a list of gradient points. Each gradient point has a position and a color. In a color gradient, the colors between two adjacent gradient points are linearly interpolated. To add a gradient point to the color gradient, pass its position and color to the AddGradientPoint() method. To retrieve a color from a specific position in the color gradient, pass that position to the GetColor() method. This class is a useful tool for coloring height maps based on elevation. Gradient example Suppose a gradient object contains the following gradient points: - -1.0 maps to black. - 0.0 maps to white. - 1.0 maps to red. If an application passes -0.5 to the GetColor() method, this method will return a gray color that is halfway between black and white. If an application passes 0.25 to the GetColor() method, this method will return a very light pink color that is one quarter of the way between white and red.
