Syntax

public abstract class BaseCamera : ICamera, 
	ILeftRightHandedCoordinateSystem

The BaseCamera type exposes the following members.

Properties

	Name	Description
	AspectRatio	Gets or sets an aspect ratio (width divided by height) of the viewport that is showing the 3D scene.
	FarPlaneDistance	Gets or sets a value that specifies the distance from the camera of the camera's far clip plane.
	IsHorizontalFieldOfView	Gets or sets a boolean that specifies if horizontal Field of View is used (true = as in WPF 3D) or vertical Field of view is used (false = as in DirectX). Default value is true.
	IsRightHandedCoordinateSystem	When true than right handed coordinate system is used (as in WPF 3D, XNA and OpenGL), if false than left handed coordinate system are used (as in DirectX). Default value is true.
	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	Returns the current position of the camera.
	GetViewProjection	Gets a precalculated View * Projection matrix.
	GetWorldViewProjection	Returns WorldViewProjection matrix. Calculating this matrix is faster inside Camera because here we can access matrixes by reference.
	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 is triggered when this camera is changed.

Fields

	Name	Description
	DefaultFarPlaneDistance	DefaultFarPlaneDistance
	DefaultNearPlaneDistance	DefaultNearPlaneDistance
