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

Namespace: Microsoft.Xna.Framework
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

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

Parameters

  • width
    Type: Single
    Width of the view volume at the near view plane.
  • height
    Type: Single
    Height of the view volume at the near view plane.
  • nearPlaneDistance
    Type: Single
    Distance to the near view plane.
  • farPlaneDistance
    Type: Single
    Distance to the far view plane.
  • result
    Type: Matrix
    [OutAttribute] The projection matrix.

Exceptions

Exception type 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.

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.
