Matrix.CreatePerspective Method (Single, Single, Single, Single)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Builds a perspective projection matrix and returns the result by value.

Namespace: Microsoft.Xna.Framework
Assembly: Microsoft.Xna.Framework.Math (in Microsoft.Xna.Framework.Math.dll)

Syntax

'Declaration
Public Shared Function CreatePerspective ( _
    width As Single, _
    height As Single, _
    nearPlaneDistance As Single, _
    farPlaneDistance As Single _
) As Matrix

public static Matrix CreatePerspective(
    float width,
    float height,
    float nearPlaneDistance,
    float farPlaneDistance
)

Parameters

width
Type: System.Single
Width of the view volume at the near view plane.

height
Type: System.Single
Height of the view volume at the near view plane.

nearPlaneDistance
Type: System.Single
Distance to the near view plane.

farPlaneDistance
Type: System.Single
Distance to the far view plane.

Return Value

Type: Microsoft.Xna.Framework.Matrix
The projection matrix.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	One of the following conditions is true: nearPlaneDistance or farPlaneDistance is a negative value. Specify a positive value for nearPlaneDistance or farPlaneDistance. nearPlaneDistance is larger than farPlaneDistance. nearPlaneDistance must be smaller than farPlaneDistance.

ArgumentOutOfRangeException

One of the following conditions is true:

nearPlaneDistance or farPlaneDistance is a negative value. Specify a positive value for nearPlaneDistance or farPlaneDistance.
nearPlaneDistance is larger than farPlaneDistance. nearPlaneDistance must be smaller than farPlaneDistance.

Remarks

Projection space refers to the space after applying projection transformation from view space. After the projection transformation, visible content has x- and y-coordinates ranging from −1 to 1, and a z-coordinate ranging from 0 to 1.

To obtain the viewable area (in world space) of a scene, create a BoundingFrustum and pass the combined view and projection matrix to the constructor.
