Class ViewportJOGL

java.lang.Object

jadex.extension.envsupport.observer.graphics.AbstractViewport

jadex.extension.envsupport.observer.graphics.opengl.ViewportJOGL

All Implemented Interfaces:

IViewport

public class ViewportJOGL
extends AbstractViewport

OpenGL/JOGL-based Viewport. This viewport attempts to use OpenGL for drawing. Exceptions/Errors may be thrown if OpenGL cannot be linked, also be sure to test isValid() afterwards to verify the availability of necessary extensions.

Constructor Detail

ViewportJOGL

public ViewportJOGL(IPerspective persp,
                    java.lang.ClassLoader classloader)

Creates a new OpenGL-based viewport. May throw UnsatisfiedLinkError and RuntimeException if linking to OpenGL fails.

Parameters:

layerObject - object holding properties for pre/postlayers

libService - library service for loading resources.

Method Detail

setSize

public void setSize(IVector2 size)

Description copied from class: AbstractViewport

Sets the size of the display area.

Specified by:

setSize in interface IViewport

Overrides:

setSize in class AbstractViewport

Parameters:

size - size of the display area, may be padded to preserve aspect ratio

refresh

public void refresh()

Description copied from interface: IViewport

Refreshes the viewport.

isValid

public boolean isValid()

Verifies the OpenGL context is valid and useable.

getTexture

public int getTexture(javax.media.opengl.GL gl,
                      java.lang.String path)

Returns a texture.

Parameters:

gl - OpenGL interface

path - resource path of the texture

Returns:

the texture

getTextRenderer

public com.sun.opengl.util.j2d.TextRenderer getTextRenderer(java.awt.Font font)

Returns an appropriate text renderer.

Parameters:

font - the font for the renderer

Returns:

the renderer

getDisplayList

public java.lang.Integer getDisplayList(java.lang.String listName)

Returns a previous generated display list or null if it doesn't exist

Parameters:

listName - name of the list

Returns:

previously generated display list

setDisplayList

public void setDisplayList(java.lang.String listName,
                           java.lang.Integer list)

Sets a display list.

Parameters:

listName - name of the list

list - the display list

getContext

public javax.media.opengl.GL getContext()

Returns the current GL rendering context.

Returns:

GL context, null if none is available

drawPrimitive

public void drawPrimitive(DrawableCombiner dc,
                          Primitive primitive,
                          java.lang.Object obj)

Draws a primitive

Parameters:

dc - The combiner.

primitive - The primitive.

obj - The object being drawn.

dispose

public void dispose()

Disposes the Viewport.
