public RenderableComponentBase()

Method Detail

getAllPropertyInfo

public PropertyInfoList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class ModelComponentBase

Returns:

static information for all exported properties

getRenderProps

public RenderProps getRenderProps()

Description copied from interface: HasRenderProps

Returns the render properities for this object. If no render properties are assigned, this routines returns null.

Specified by:

getRenderProps in interface HasRenderProps

Returns:

current render properties for this object

setRenderProps

public void setRenderProps(RenderProps props)

Description copied from interface: HasRenderProps

Assigns a new set of render properties to this object. An argument of null will remove render properties from this object.

Specified by:

setRenderProps in interface HasRenderProps

Parameters:

props - new render properties for this object

prerender

public void prerender(RenderList list)

Description copied from interface: IsRenderable

Called prior to rendering to allow this object to update the internal state required for rendering (such as by caching rendering coordinates). The object may add internal objects to the list of objects being rendered, by calling

list.addIfVisible (obj);

for each of the objects in question.

Specified by:

prerender in interface IsRenderable

Parameters:

list - list of objects to be rendered

updateBounds

public void updateBounds(Vector3d pmin,
                         Vector3d pmax)

Description copied from interface: IsRenderable

Update the minimum and maximum points for this object. In an x-y-z coordinate system with x directed to the right and y directed upwards, the minimum and maximum points can be thought of as defining the left-lower-far and right-upper-near corners of a bounding cube. This method should only reduce the elements of the minimum point and increase the elements of the maximum point, since it may be used as part of an iteration to determine the bounding cube for several different objects.

Specified by:

updateBounds in interface IsRenderable

Parameters:

pmin - minimum point

pmax - maximum point

render

public abstract void render(Renderer renderer,
                            int flags)

Description copied from interface: IsRenderable

Render this object using the functionality of the supplied Renderer.

Specified by:

render in interface IsRenderable

Parameters:

renderer - provides the functionality used to perform the rendering.

flags - flags that may be used to control different aspects of the rendering. Flags are defined in Renderer and currently include Renderer.HIGHLIGHT and Renderer.SORT_FACES.

getSelection

public void getSelection(java.util.LinkedList<java.lang.Object> list,
                         int qid)

Description copied from interface: IsSelectable

Append to list the component (or components) associated with the qid-th selection query issued by this component's render method. This will only be called if this component manages its own selection (i.e., the number nums returned by IsSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.

Specified by:

getSelection in interface IsSelectable

Parameters:

list - selected objects are appended to the end of this list

qid - index of the selection query

createRenderProps

public RenderProps createRenderProps()

Description copied from interface: HasRenderProps

Factory method to create render properties appropriate to this object.

Specified by:

createRenderProps in interface HasRenderProps

Returns:

new render properties for this object

defaultRenderPropsAreNull

public boolean defaultRenderPropsAreNull()

getRenderHints

public int getRenderHints()

Description copied from interface: IsRenderable

Returns a bit code giving rendering hints about this renderable. Current bit codes include TRANSPARENT and TWO_DIMENSIONAL.

Specified by:

getRenderHints in interface IsRenderable

Returns:

bit code of rendering hints.

isSelectable

public boolean isSelectable()

Returns true if this object is in fact selectable.

Specified by:

isSelectable in interface IsSelectable

Returns:

true if this object is selectable

numSelectionQueriesNeeded

public int numSelectionQueriesNeeded()

Description copied from interface: IsSelectable

If this selectable manages its own selection (by issuing selection queries within its render method), then this method should return the maximum number of selection queries that will be required. Otherwise, this method should return -1.

Specified by:

numSelectionQueriesNeeded in interface IsSelectable

Returns:

maximum number of selection queries needed by this component, or -1 if this component does not manage its own selection.

copy

public RenderableComponentBase copy(int flags,
                                    java.util.Map<ModelComponent,ModelComponent> copyMap)

Overrides:

copy in class ModelComponentBase

updateRenderProps

public static RenderProps updateRenderProps(ModelComponent comp,
                                            RenderProps props,
                                            RenderProps setProps)

isVisible

public static boolean isVisible(RenderableComponent rcomp)

setVisible

public static boolean setVisible(RenderableComponent rcomp,
                                 boolean enable)
