public abstract class SimpleTransformable
extends SimpleRenderable

Extends SimpleRenderable to include a world space transform so that subclasses can render themselves in model space.

Constructor Detail

SimpleTransformable

public SimpleTransformable(GlContext ctx)

Creates a new simple transformable.

SimpleTransformable

public SimpleTransformable(GlContext ctx,
                           String queue)

Creates a new simple transformable.

Parameters:

queue - the name of the queue into which we place the batch.

SimpleTransformable

public SimpleTransformable(GlContext ctx,
                           String queue,
                           int priority)

Creates a new simple transformable.

Parameters:

queue - the name of the queue into which we place the batch.

priority - the priority level at which to enqueue the batch.

SimpleTransformable

public SimpleTransformable(GlContext ctx,
                           String queue,
                           int priority,
                           boolean modifiesColorState,
                           int primitiveCount)

Creates a new simple transformable.

Parameters:

queue - the name of the queue into which we place the batch.

priority - the priority level at which to enqueue the batch.

modifiesColorState - if true, invalidate the color state after calling the SimpleRenderable.draw() method.

primitiveCount - the primitive count to report to the renderer.

SimpleTransformable

protected SimpleTransformable()
