Class ColladaMeshShape.OrderedMeshShape

java.lang.Object
  gov.nasa.worldwind.ogc.collada.impl.ColladaMeshShape.OrderedMeshShape

All Implemented Interfaces:

OrderedRenderable, Renderable

Enclosing class:

ColladaMeshShape

public static class ColladaMeshShape.OrderedMeshShape
extends Object
implements OrderedRenderable

Class to represent an instance of the mesh to be drawn as an ordered renderable. We can't use the mesh itself as the ordered renderable because it may be drawn multiple times with different transforms.

Field Summary

protected double	eyeDistance Distance from the eye to the shape's reference position.
protected ColladaMeshShape	mesh Shape to render.
protected Matrix	renderMatrix Transform applied to this instance of the mesh.

Constructor Summary

ColladaMeshShape.OrderedMeshShape(ColladaMeshShape mesh, Matrix renderMatrix, double eyeDistance)
Create a new ordered renderable.

Method Summary

double	getDistanceFromEye() Returns the ordered renderable's distance from the current view's eye point.
void	pick(DrawContext dc, Point pickPoint) Executes a pick of the ordered renderable.
void	render(DrawContext dc) Causes this Renderable to render itself using the provided draw context.

Constructor Detail

ColladaMeshShape.OrderedMeshShape

public ColladaMeshShape.OrderedMeshShape(ColladaMeshShape mesh,
                                         Matrix renderMatrix,
                                         double eyeDistance)

Create a new ordered renderable.

Parameters:

mesh - Mesh shape to render.

renderMatrix - Transform matrix to apply when rendering the shape.

eyeDistance - Distance from the eye position to the shape's reference position.

Method Detail

getDistanceFromEye

public double getDistanceFromEye()

Description copied from interface: OrderedRenderable

Returns the ordered renderable's distance from the current view's eye point. Intended to be used only to sort a list of ordered renderables according to eye distance, and only during frame generation when a view is active.

Specified by:

getDistanceFromEye in interface OrderedRenderable

Returns:

the distance of the ordered renderable from the current view's eye point.

pick

public void pick(DrawContext dc,
                 Point pickPoint)

Description copied from interface: OrderedRenderable

Executes a pick of the ordered renderable.

Specified by:

pick in interface OrderedRenderable

Parameters:

dc - the current draw context.

pickPoint - the pick point.

render

public void render(DrawContext dc)

Description copied from interface: Renderable

Causes this Renderable to render itself using the provided draw context.

Specified by:

render in interface Renderable

Parameters:

dc - the DrawContext to be used
