Syntax

public class MatrixCamera : ICamera

The MatrixCamera type exposes the following members.

Constructors

	Name	Description
	MatrixCamera	Constructor
	MatrixCamera(Matrix, Matrix)	Constructor

Properties

	Name	Description
	AspectRatio	Gets or sets the camera's aspect ration - calculated as viewport's width / height.
	FarPlaneDistance	Gets or sets a value that specifies the distance from the camera of the camera's far clip plane.
	NearPlaneDistance	Gets or sets a value that specifies the distance from the camera of the camera's near clip plane.
	ParentDXScene	Gets or sets the DXScene that this camera belong to.
	ParentSceneNode	Gets or sets a parent SceneNode that can be used to adjust the camera's View matrix with the SceneNode's world matrix. This can be used to animate the camera with SceneNode.
	Projection	Gets the camera's projection matrix.
	ProjectionType	Gets type of projection (Perspective or Orthographic)
	View	Gets the camera's view matrix.

Methods

	Name	Description
	GetCameraPosition	Gets the camera's position. The position is calculating with inverting the view matrix and extracting the values from 4th row. The invert operation can be skipped with calling SetCameraPosition(Vector3) method.
	GetViewProjection	Gets a pre-calculated View * Projection matrix.
	GetWorldViewProjection	Returns WorldViewProjection matrix. Calculating this matrix is faster inside Camera because here we can access matrixes by reference.
	SetCameraPosition	Sets camera's position. This prevents calling invert on view matrix when the GetCameraPosition is called. This method should be called after setting View matrix.
	Update	Update method updates the camera matrices when needed (when there were any change in the camera properties) or when forceMatrixUpdate is set to true.

Events

	Name	Description
	CameraChanged	CameraChanged event occurs after the camera was changed.
