Constructor Detail

PolygonizationCache

public PolygonizationCache(GraphState gs,
                           int flags,
                           float flatness,
                           boolean shareLists)

Constructs a new cache. The parameters will be passed to Polygonization.polygonize(de.grogra.graph.ContextDependent, de.grogra.graph.GraphState, de.grogra.imp3d.PolygonArray, int, float) when a cache entry is to be computed.

Parameters:

gs - the graph state within which the cache will be used

flags - the flags to pass to polygonize

flatness - the flatness to pass to polygonize

shareLists - shall the returned PolygonArrays share their lists (vertices, normals etc.)? This is useful where the returned data is copied into another representation and no longer needed

Method Detail

createEntry

protected Cache.Entry createEntry(java.lang.Object obj,
                                  boolean node,
                                  ContextDependent dep,
                                  java.lang.Object strategy)

Specified by:

createEntry in class Cache

get

public PolygonArray get(java.lang.Object object,
                        boolean asNode,
                        Polygonizable p)

Returns the PolygonArray of a Polygonizable in the given object context.

Parameters:

object - the context

asNode - true if object is a node, false if object is an edge

p - the polygonizable

Returns:

a PolygonArray, computed by p
