Constructors

PointSpecular(IntPtr)

Initializes a new instance of the PointSpecular class.

public PointSpecular(IntPtr nativePtr)

Parameters

nativePtr System.IntPtr

The native pointer.

Properties

Color

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

public Vector3 Color { get; set; }

Property Value

Vector3

KernelUnitLength

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.

public Vector2 KernelUnitLength { get; set; }

Property Value

Vector2

LightPosition

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.

public Vector3 LightPosition { get; set; }

Property Value

Vector3

ScaleMode

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.

public PointSpecularScaleMode ScaleMode { get; set; }

Property Value

PointSpecularScaleMode

SpecularConstant

The ratio of specular reflection to the incoming light. The value is unitless and must be between 0 and 10,000.

public float SpecularConstant { get; set; }

Property Value

float

SpecularExponent

The exponent for the specular term in the Phong lighting equation. A larger value corresponds to a more reflective surface. The value is unitless and must be between 1.0 and 128.

public float SpecularExponent { get; set; }

Property Value

float

SurfaceScale

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

public float SurfaceScale { get; set; }

Property Value

float

Methods

Create(DeviceContext)

Returns
