List<BlendTriangle>	getBlendedTris() Because blending phase of rendering can be done only after all opaque objects has been drawn and because polys has to be back-to-front ordered every renderer will return list of its blended triangles so final renderer can sort all blended triangles from all blended renderers and do it correctly.

Method Detail

addSubRenderer

public void addSubRenderer(ISubGLRenderer<T> subrenderer)

Add renderer to collection. It will be rendered after all previous renders are drawn.

Parameters:

subrenderer -

removeSubRenderer

public boolean removeSubRenderer(ISubGLRenderer<T> subrenderer)

Remove subrenderer from collection

Parameters:

subrenderer - renderer to be removed

Returns:

true if subrenderes was in collection

getSubRenderes

public List<ISubGLRenderer<T>> getSubRenderes()

List of subrenderes.

Returns:

Unmodifiable list of subrenderes.

getRenderersOf

public List<ISubGLRenderer<T>> getRenderersOf(T o)

Return list of renderers that draw passed object

Returns:

list of renderers with object o, empty list if no found

removeRenderersOf

public void removeRenderersOf(T o)

Remove all renderers that draw object o.

Parameters:

o - object that may have renderers in collection we want to remove

getDrawnObjects

public Set<T> getDrawnObjects()

Get set of all objects this collection draws.

Returns:

all objects this collection draws

render

public void render(javax.media.opengl.GL gl)

Description copied from interface: ISubGLRenderer

Display stuff you want to. Assume that settings have already been set in GLRendererCollection

Specified by:

render in interface ISubGLRenderer<GLRendererCollection<T>>

getObject

public GLRendererCollection<T> getObject()

Description copied from interface: ISubGLRenderer

Return object this renderer draws. Because objects we want to draw can change rapidly, we have to remove and add subrenderers based on passed objects (renderer R draws object A, now we don't want to draw A anymore, we have to go through subrenderers to find which ones draws it).

Specified by:

getObject in interface ISubGLRenderer<GLRendererCollection<T>>

Returns:

Object this renderer draws.

prepare

public void prepare(javax.media.opengl.GL gl)

Prepare all renderers for rendering

Specified by:

prepare in interface ISubGLRenderer<GLRendererCollection<T>>

Parameters:

gl -

getBlendedTris

public List<BlendTriangle> getBlendedTris()

Description copied from interface: ISubGLRenderer

Because blending phase of rendering can be done only after all opaque objects has been drawn and because polys has to be back-to-front ordered every renderer will return list of its blended triangles so final renderer can sort all blended triangles from all blended renderers and do it correctly.

Specified by:

getBlendedTris in interface ISubGLRenderer<GLRendererCollection<T>>

Returns:

List of blended triangles this renderer wants to render. Empty collection if no such exists.
