Constructor Detail

OGLRenderingEffects

public OGLRenderingEffects(org.j3d.aviatrix3d.SimpleScene scene)

Construct a default instance initialised to have a mode of shaded rendering.

Method Detail

preDraw

public void preDraw(javax.media.opengl.GL gl,
                    java.lang.Object userData)

Perform any pre-rendering setup that you may need for this scene. After this call, all normal scene graph rendering is performed by the surface.

Specified by:

preDraw in interface org.j3d.aviatrix3d.rendering.RenderEffectsProcessor

Parameters:

gl - The current GL context wrapper to draw with

userData - Some identifiable data provided by the user

postDraw

public void postDraw(javax.media.opengl.GL gl,
                     org.j3d.aviatrix3d.rendering.ProfilingData profilingData,
                     java.lang.Object userData)

Perform any post-rendering actions that you may need for this scene. Called after the renderer has completed all drawing and just before the buffer swap. The only thing to be called after calling this method is glFlush().

Specified by:

postDraw in interface org.j3d.aviatrix3d.rendering.RenderEffectsProcessor

Parameters:

gl - The current GL context wrapper to draw with

userData - Some identifiable data provided by the user

addProfilingListener

public void addProfilingListener(ProfilingListener l)

Request notification of profiling information.

Parameters:

l - The listener

removeProfilingListener

public void removeProfilingListener(ProfilingListener l)

Remove notification of profiling information.

Parameters:

l - The listener

setRenderingStyle

public void setRenderingStyle(int style)
                       throws java.lang.IllegalArgumentException

Change the rendering style that the browser should currently be using. Various options are available based on the constants defined in this interface.

Parameters:

style - One of the RENDER_* constants

Throws:

java.lang.IllegalArgumentException - A style constant that is not recognized by the implementation was provided

getRenderingStyle

public int getRenderingStyle()

Get the currently set rendering style. The default style is RENDER_SHADED.

Returns:

one of the RENDER_ constants

captureScreenOnce

public void captureScreenOnce(ScreenCaptureListener listener,
                              int width,
                              int height)

Capture the screen on the next render.

Parameters:

listener - Listener for capture results

width - The screen width

height - The screen height

captureScreenStart

public void captureScreenStart(ScreenCaptureListener listener,
                               int width,
                               int height)

Capture the screen on each render.

Parameters:

listener - Listener for capture results

width - The screen width

height - The screen height

captureScreenEnd

public void captureScreenEnd()

Stop cpaturing the screen on each render.
