Method Detail

prepareAndExecuteDraw

public final void prepareAndExecuteDraw(DrawableCombiner dc,
                                        Primitive primitive,
                                        java.lang.Object obj,
                                        ViewportJOGL vp)

Prepares the object for rendering to a JOGL viewport

Specified by:

prepareAndExecuteDraw in interface IGLRenderer

Parameters:

dc - the DrawableCombiner drawing the object

primitive - the primitive being drawn

obj - the object being drawn

vp - the viewport

setupMatrix

protected boolean setupMatrix(DrawableCombiner dc,
                              Primitive primitive,
                              java.lang.Object obj,
                              javax.media.opengl.GL gl,
                              IViewport vp)

Sets up the transformation matrix before drawing.

Parameters:

obj - object being drawn

g - graphics context

Returns:

true, if the setup was successful

setupDCMatrix

public static final boolean setupDCMatrix(DrawableCombiner dc,
                                          java.lang.Object obj,
                                          boolean enablePos,
                                          boolean enableSize,
                                          boolean enableRot,
                                          ViewportJOGL vp)

Sets the basic matrix for the combiner, call can be skipped if alternative draw method is required.

Parameters:

obj - object being drawn

gl - the viewport context

enablePos - enables position setup

enableSize - enables size setup

enableRot - enables rotation setup

draw

public abstract void draw(DrawableCombiner dc,
                          Primitive primitive,
                          java.lang.Object obj,
                          ViewportJOGL vp)

Draws the primitive.

Specified by:

draw in interface IGLRenderer

Parameters:

dc - the DrawableCombiner drawing the object

primitive - the primitive being drawn

obj - the object being drawn

vp - the viewport
