Matrix.CreatePerspectiveOffCenter Method (Single, Single, Single, Single, Single, Single, Matrix%)

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

Builds a customized, perspective projection matrix.

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

Syntax

'Declaration
Public Shared Sub CreatePerspectiveOffCenter ( _
    left As Single, _
    right As Single, _
    bottom As Single, _
    top As Single, _
    nearPlaneDistance As Single, _
    farPlaneDistance As Single, _
    <OutAttribute> ByRef result As Matrix _
)

public static void CreatePerspectiveOffCenter(
    float left,
    float right,
    float bottom,
    float top,
    float nearPlaneDistance,
    float farPlaneDistance,
    out Matrix result
)

Parameters

  • left
    Type: System.Single
    Minimum x-value of the view volume at the near view plane.
  • right
    Type: System.Single
    Maximum x-value of the view volume at the near view plane.
  • bottom
    Type: System.Single
    Minimum y-value of the view volume at the near view plane.
  • top
    Type: System.Single
    Maximum y-value 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 of the far view plane.

Exceptions

Exception Condition
ArgumentOutOfRangeException

One of the following conditions is true:

  1. nearPlaneDistance or farPlaneDistance is a negative value. Specify a positive value for nearPlaneDistance or farPlaneDistance.

  2. nearPlaneDistance 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.
