Method Details

mergeGeometries

public static void mergeGeometries(Collection<Geometry> geometries,
 Mesh outMesh)

Merges all geometries in the collection into the output mesh. Creates a new material using the TextureAtlas.

Parameters:

geometries - the geometries to merge

outMesh - a Mesh to receive the geometries

makeLods

public static void makeLods(Collection<Geometry> geometries,
 Mesh outMesh)

makeBatches

public static List<Geometry> makeBatches(Collection<Geometry> geometries)

makeBatches

public static List<Geometry> makeBatches(Collection<Geometry> geometries,
 boolean useLods)

Batches a collection of Geometries so that all with the same material get combined.

Parameters:

geometries - The Geometries to combine

useLods - true→generate levels of detail, false→don't generate them

Returns:

A List of newly created Geometries, each with a distinct material

gatherGeoms

public static void gatherGeoms(Spatial scene,
 List<Geometry> geoms)

optimize

public static Spatial optimize(Node scene)

Optimizes a scene by combining Geometry with the same material. All Geometries found in the scene are detached from their parent and a new Node containing the optimized Geometries is attached.

Parameters:

scene - The scene to optimize

Returns:

The newly created optimized geometries attached to a node

optimize

public static Node optimize(Node scene,
 boolean useLods)

Optimizes a scene by combining Geometry with the same material. All Geometries found in the scene are detached from their parent and a new Node containing the optimized Geometries is attached.

Parameters:

scene - The scene to optimize

useLods - true if you want the resulting geometry to keep lod information

Returns:

The newly created optimized geometries attached to a node

printMesh

public static void printMesh(Mesh mesh)

main

public static void main(String[] args)

alignBuffers

public static void alignBuffers(Node n,
 GeometryBatchFactory.AlignOption option)

Will ensure that all the geometries' meshes of the n sub graph have the same types of buffers

Parameters:

n - the node to gather geometries from

option - the align options
