Class WorldRenderableObject

java.lang.Object
  org.deegree.rendering.r3d.model.WorldObject<RenderableQualityModelPart,RenderableQualityModel>
      org.deegree.rendering.r3d.opengl.rendering.model.geometry.WorldRenderableObject

All Implemented Interfaces:

Serializable, MemoryAware, JOGLRenderable, PositionableModel

Direct Known Subclasses:

RenderablePrototype

public class WorldRenderableObject
extends WorldObject<RenderableQualityModelPart,RenderableQualityModel>
implements JOGLRenderable

The WorldRenderableObject defines a number of renderable quality levels, where each level may be a PrototypeReference or a RenderableGeometry model. Which LOD is should be rendered is deterimined by applying the LODSwitcher to the position and the error scalar.

Method Detail

render

public void render(RenderContext glRenderContext)

Description copied from interface: JOGLRenderable

Called to render this object to an OpenGL context.

The following pre-conditions hold:

• The projection matrix of context has been set up correctly by the caller.
• The view parameters params matches the projection and the screen size, so the callee can depend on them to perform view frustum culling and LOD adaptation.

Specified by:

render in interface JOGLRenderable

Parameters:

glRenderContext - TODO

renderPrepared

public void renderPrepared(RenderContext glRenderContext,
                           DirectGeometryBuffer geomBuffer)

This method assumes the coordinates and normals are located in the given DirectGeometryBuffer.

Parameters:

glRenderContext -

geomBuffer - to be get the coordinates from.

calcQualityLevel

protected int calcQualityLevel(RenderContext glRenderContext)

Parameters:

glRenderContext -

Returns:

the level to render.

getOrdinateCount

public int getOrdinateCount()

Returns:

the number of ordinates in all qualitylevels, needed for the initialization of the direct buffer.

getTextureOrdinateCount

public int getTextureOrdinateCount()

Returns:

the number of ordinates in all qualitylevels, needed for the initialization of the direct buffer.

setSwitchLevels

public void setSwitchLevels(LODSwitcher switchLevels)

Parameters:

switchLevels -
