Constructor Detail

AreaElement

public AreaElement(GlContext ctx)

Creates a new area element.

Method Detail

setVertices

public void setVertices(TudeySceneModel.Vertex[] vertices)

Sets the vertices of the area.

getColor

public Color4f getColor()

Returns a reference to the outline color.

setVisible

public void setVisible(boolean visible)

Update the visibility.

getIntersection

public boolean getIntersection(Ray3D ray,
                               Vector3f result)

Description copied from interface: Intersectable

Finds the intersection of a ray with this object and places it in the supplied vector (if it exists).

Specified by:

getIntersection in interface Intersectable

Overrides:

getIntersection in class SimpleSceneElement

Returns:

true if the ray intersected the object (in which case the result will contain the point of intersection), false otherwise.

createStates

protected RenderState[] createStates()

Description copied from class: SimpleRenderable

Creates the state set for this object.

Overrides:

createStates in class SimpleTransformable

computeBounds

protected void computeBounds(Box result)

Description copied from class: SimpleSceneElement

Computes the bounds of the element and places them in the provided result object. The default implementation simply transforms the bounds returned by SimpleSceneElement.getLocalBounds().

Overrides:

computeBounds in class SimpleSceneElement

draw

protected void draw()

Description copied from class: SimpleRenderable

Draws the geometry in immediate mode.

Overrides:

draw in class SimpleRenderable

getCenter

protected Vector3f getCenter()

Description copied from class: SimpleTransformable

Returns the transformable's model space center.

Overrides:

getCenter in class SimpleTransformable
