Matrix.CreatePerspectiveFieldOfView Method (Single, Single, Single, Single)

Builds a perspective projection matrix based on a field of view and returns by value.

Syntax

'Declaration
Public Shared Function CreatePerspectiveFieldOfView ( _
         fieldOfView As Single, _
         aspectRatio As Single, _
         nearPlaneDistance As Single, _
         farPlaneDistance As Single _
) As Matrix 

public static Matrix CreatePerspectiveFieldOfView (
         float fieldOfView,
         float aspectRatio,
         float nearPlaneDistance,
         float farPlaneDistance
)

public:
static Matrix CreatePerspectiveFieldOfView(
         float fieldOfView,
         float aspectRatio,
         float nearPlaneDistance,
         float farPlaneDistance
)

Parameters

• fieldOfView
  Type: Single
  Field of view in the y direction, in radians.

• aspectRatio
  Type: Single

  Aspect ratio, defined as view space width divided by height.

  To match the aspect ratio of the viewport, the property AspectRatio.

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

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

Return Value

Type: Matrix
The perspective projection matrix.

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	One of the following conditions is true: fieldOfView is not between 0 and pi (180 degrees). Note that fieldOfView should be specified in radians. 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.
