Constructor Detail

RenderableComponentBase

public RenderableComponentBase()
Method Detail

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: GLRenderable
Prepare for rendering, and potentially add itself to a list to be drawn by a GLRenderer.

Specified by:
prerender in interface GLRenderable

updateBounds

public void updateBounds(Point3d pmin,
                         Point3d pmax)
Description copied from interface: GLRenderable
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 GLRenderable
Parameters:
pmin - minimum point
pmax - maximum point

render

public abstract void render(GLRenderer renderer,
                            int flags)
Description copied from interface: GLRenderable
Render this object using Open GL via the JOGL.

Specified by:
render in interface GLRenderable
Parameters:
renderer - renderer object which is used to perform the rendering. Provides pointers to GL and GLU, along with helper functions.
flags - supplies flags that may be used to control different aspects of the rendering. Flags are defined in GLRenderer and currently include GLRenderer.SELECTED, GLRenderer.VERTEX_COLORING, GLRenderer.HSV_COLOR_INTERPOLATION, GLRenderer.SORT_FACES, and GLRenderer.CLEAR_MESH_DISPLAY_LISTS.

getSelection

public void getSelection(java.util.LinkedList<java.lang.Object> list,
                         int qid)
Description copied from interface: GLSelectable
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 GLSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.

Specified by:
getSelection in interface GLSelectable
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

updateRenderProps

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

getRenderHints

public int getRenderHints()
Description copied from interface: GLRenderable
Returns a bit code giving rendering hints about this renderable. Current bit codes include TRANSLUCENT.

Specified by:
getRenderHints in interface GLRenderable
Returns:
bit code of rendering hints.

isSelectable

public boolean isSelectable()
Returns true if this object is in fact selectable.

Specified by:
isSelectable in interface GLSelectable
Returns:
true if this object is selectable

numSelectionQueriesNeeded

public int numSelectionQueriesNeeded()
Description copied from interface: GLSelectable
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 GLSelectable
Returns:
maximum number of selection queries needed by this component, or -1 if this component does not manage its own selection.

copy

public ModelComponent copy(int flags,
                           java.util.Map<ModelComponent,ModelComponent> copyMap)
Overrides:
copy in class ModelComponentBase
