Initializes a new instance of the PointDiffuse class.

The color of the incoming light. This property is exposed as a Vector3 – (R, G, B) and used to compute LR, LG, LB.

The ratio of diffuse reflection to amount of incoming light. This property must be between 0 and 10,000 and is unitless.

The size of an element in the Sobel kernel used to generate the surface normal in the X and Y direction. This property maps to the dx and dy values in the Sobel gradient. This property is a Vector2 (Kernel Unit Length X, Kernel Unit Length Y) and is defined in (device-independent pixels (DIPs)/Kernel Unit). The effect uses bilinear interpolation to scale the bitmap to match size of kernel elements.

The light position of the point light source. The property is a D2D1_VECTOR_3F defined as (x, y, z). The units are in device-independent pixels (DIPs) and the values are unitless and unbounded.

The interpolation mode the effect uses to scale the image to the corresponding kernel unit length. There are six scale modes that range in quality and speed. If you don't select a mode, the effect uses the interpolation mode of the device context. See Scale modes for more info.

The scale factor in the Z direction. The value is unitless and must be between 0 and 10,000.
