Detailed Description

A camera in 3-space.

Camera is an abstract class that is the base for both PerspectiveCamera and OrthographicCamera. These classes are used to define the view on a scenegraph and the projection for rendering onto the screen.

Member Function Documentation

virtual void FitToWnd (  int  width, int  height )  [pure virtual]

Adjusts the camera to fit the shape of a window. When a camera is attached to a Wnd via Wnd::AdjustCamera, the Wnd object will call this member function when it is resized. It is not usually necessary to call this method manually. Implemented in OrthographicCamera, and PerspectiveCamera.

float GetFarDistance (   )  [inline]

Returns the distance to the far clip plane.

float GetNearDistance (   )  [inline]

Returns the distance to the near clip plane.

void LookAt (  float  x, float  y, float  z )  [inline]

Points the camera towards the given point.

void LookAt (  const Vec &  target  )  [inline]

Points the camera towards the given point.

virtual void Render (   )  [pure virtual]

"Draws" the camera Sets the view on the scene, and initializes the OpenGL projection matrix. Implements Node. Implemented in OrthographicCamera, and PerspectiveCamera.

void SetFarDistance (  float  farDist  )  [inline]

Sets the distance to the far clip plane.

void SetNearDistance (  float  nearDist  )  [inline]

Sets the distance to the near clip plane.

void SetOrientation (  float  x, float  y, float  z )  [inline]

Specifies the direction of the up vector.

void SetOrientation (  const Vec &  orient  )  [inline]

Specifies the direction of the up vector.

void SetPosition (  float  x, float  y, float  z )  [inline]

Sets the camera's position.

void SetPosition (  const Vec &  pos  )  [inline]

Sets the camera's position.
