Member Function Documentation

virtual void FitToWnd (  int  width, int  height )  [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. Implements Camera.

float GetAspectRatio (   )  [inline]

Returns the camera's aspect ratio. In general, the aspect ratio of a camera should match the aspect ratio of the viewport. Wnd::AdjustCamera can be used to ensure that the two are consistent.

float GetFOV (   )  [inline]

Returns the camera's field of view.

void Render (   )  [virtual]

"Draws" the camera Sets the view on the scene, and initializes the OpenGL projection matrix. Implements Camera.

void SetAspectRatio (  float  aspectRatio  )  [inline]

Sets the camera's aspect ratio. The aspect ratio that determines the field of view in the x direction.

void SetFOV (  float  fov  )  [inline]

Sets the camera's field of view. The field of view is the angle, in degrees, in the y-direction that determines the vertical size of the view plane. See the man page for gluPerspective, or chapter 3 of the OpenGL Programming Guide for more information.
