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

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

Syntax

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

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.

Return Value

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.
