Parameters

face

Face to color

vertex_x

X coordinate of vertex to color

vertex_y

Y coordinate of vertex to color

vertex_z

Z coordinate of vertex to color

normal_x

X coordinate of normal to color

normal_y

Y coordinate of normal to color

normal_z

Z coordinate of normal to color

Value

Function of the specified face or coordinates of the model (see Remarks)

Return Value

Not used

When you implement this method, you need to populate the Value output parameter. Value can be a function of the specified coordinates or the properties of the face. By default Value is the input parameter for ISwColorContour1::Color and ISwColorContour1::DisplayString.

In VB.NET implementations, you need to change the name of the Value output parameter to avoid a compiler error. When you change the name, use same name for the input parameters of your ISwColorContour1::Color and ISwColorContour1::DisplayString implementations.
