Class LWJGLCamera

java.lang.Object
  com.jme.renderer.AbstractCamera
      com.jme.renderer.lwjgl.LWJGLCamera

All Implemented Interfaces:

Camera, java.io.Serializable

public class LWJGLCamera

extends AbstractCamera

LWJGLCamera defines a concrete implementation of a AbstractCamera using the LWJGL library for view port setting. Most functionality is provided by the AbstractCamera class with this class handling the OpenGL specific calls to set the frustum and viewport.

Constructor Detail

LWJGLCamera

public LWJGLCamera(int width,
                   int height,
                   java.lang.Object parent)

Constructor instantiates a new LWJGLCamera object. The width and height are provided, which cooresponds to either the width and height of the rendering window, or the resolution of the fullscreen display.

Parameters:

width - the width/resolution of the display.

height - the height/resolution of the display.

Method Detail

resize

public void resize(int width,
                   int height)

resize resizes this cameras view with the given width/height. This is similar to constructing a new camera, but reusing the same Object.

Parameters:

width - int

height - int

onFrustumChange

public void onFrustumChange()

onFrustumChange updates the frustum when needed. It calls super to set the new frustum values then sets the OpenGL frustum.

Specified by:

onFrustumChange in interface Camera

Overrides:

onFrustumChange in class AbstractCamera

See Also:

Camera.onFrustumChange()

onViewPortChange

public void onViewPortChange()

onViewportChange updates the viewport when needed. It calculates the viewport coordinates and then calls OpenGL's viewport.

See Also:

Camera.onViewPortChange()

onFrameChange

public void onFrameChange()

onFrameChange updates the view frame when needed. It calls super to update the data and then uses GLU's lookat function to set the OpenGL frame.

Specified by:

onFrameChange in interface Camera

Overrides:

onFrameChange in class AbstractCamera

See Also:

Camera.onFrameChange()
