Parameters
- viewport
- Type: Viewport
The Viewport. - position
- Type: DigitalRune.Mathematics.AlgebraVector3F
The position in screen space: The x- and y-components define the pixel position. The
z-component defines the depth in clip space. (The depth of the clipping volume ranges from
MinDepth to MaxDepth - usually [0, 1].)
- projection
- Type: DigitalRune.Mathematics.AlgebraMatrix44F
The projection matrix. - view
- Type: DigitalRune.Mathematics.AlgebraMatrix44F
The view matrix. - world
- Type: DigitalRune.Mathematics.AlgebraMatrix44F
The world matrix.
Return Value
Type:
Vector3FThe position in object space.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
Viewport. When you use instance method syntax to call this method, omit the first parameter. For more information, see
