BuildingRenderer

public BuildingRenderer(Envelope sceneDomain,
                        int numberOfObjectsInLeaf,
                        DirectGeometryBuffer geometryBuffer,

Parameters:

sceneDomain -

numberOfObjectsInLeaf -

geometryBuffer - wrapper holding all geometries in a single direct FloatBuffer

maxPixelError -

levels - configured values for switching between different lods of the buildings.

Method Detail

add

public boolean add(WorldRenderableObject renderable)

Specified by:

add in interface Collection<WorldRenderableObject>

Overrides:

add in class RenderableManager<WorldRenderableObject>

addAll

public boolean addAll(Collection<? extends WorldRenderableObject> c)

Specified by:

addAll in interface Collection<WorldRenderableObject>

Overrides:

addAll in class RenderableManager<WorldRenderableObject>

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.

Parameters:

glRenderContext - TODO

getGeometryBuffer

public DirectGeometryBuffer getGeometryBuffer()

Returns:

the geometry buffer used for rendering.
