IsRenderableHolder

public IsRenderableHolder(IsRenderable renderable)

Method Detail

getAllPropertyInfo

public PropertyList 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

Overrides:

getRenderProps in class RenderableComponentBase

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

Overrides:

setRenderProps in class RenderableComponentBase

Parameters:

props - new render properties for this object

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

Overrides:

createRenderProps in class RenderableComponentBase

Returns:

new render properties for this object

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

Overrides:

getRenderHints in class RenderableComponentBase

Returns:

bit code of rendering hints.

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

Overrides:

updateBounds in class RenderableComponentBase

Parameters:

pmin - minimum point

pmax - maximum point

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

Overrides:

prerender in class RenderableComponentBase

Parameters:

list - list of objects to be rendered

render

public 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

Specified by:

render in class RenderableComponentBase

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.

isSelectable

public boolean isSelectable()

Description copied from class: RenderableComponentBase

Returns true if this object is in fact selectable.

Specified by:

isSelectable in interface IsSelectable

Overrides:

isSelectable in class RenderableComponentBase

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

Overrides:

numSelectionQueriesNeeded in class RenderableComponentBase

Returns:

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

getRenderable

public IsRenderable getRenderable()

write

public void write(java.io.PrintWriter writer,
                  NumberFormat fmt,
                  java.lang.Object ref)
           throws java.io.IOException

Description copied from class: ModelComponentBase

Writes a text description of this element to a PrintWriter. The text description should be compatable with scan and complete enough to allow full reconstruction of the element.

Specified by:

write in interface Scannable

Overrides:

write in class ModelComponentBase

Parameters:

writer - stream for writing the element

fmt - numeric formating information

ref - optional reference object which can be used for producing references to other objects

Throws:

java.io.IOException - if an I/O error occured
