Class NMLModelLODTreeLayer

java.lang.Object

com.nutiteq.layers.Layer

com.nutiteq.layers.NMLModelLODTreeLayer

public class NMLModelLODTreeLayer
extends Layer

An advanced layer for 3D models that supports automatic Level of Detail (LOD) calculation based on view.
Should be used together with corresponding data source.

Constructor Detail

NMLModelLODTreeLayer

public NMLModelLODTreeLayer(long cPtr,
                            boolean cMemoryOwn)

NMLModelLODTreeLayer

public NMLModelLODTreeLayer(NMLModelLODTreeDataSource dataSource)

Constructs a NMLModelLODTreeLayer object from a data source.

Parameters:

dataSource - The data source from which this layer loads data.

Method Detail

getCPtr

public static long getCPtr(NMLModelLODTreeLayer obj)

finalize

protected void finalize()

Overrides:

finalize in class Layer

delete

public void delete()

Overrides:

delete in class Layer

swigCreatePolymorphicInstance

public static NMLModelLODTreeLayer swigCreatePolymorphicInstance(long cPtr,
                                                                 boolean cMemoryOwn)

Creates a polymorphic instance of the given native object. This is used internally by the SDK.

getDataSource

public NMLModelLODTreeDataSource getDataSource()

Returns the data source of this layer.

Returns:

The data source that was bound to this vector layer on construction.

getMaxMemorySize

public long getMaxMemorySize()

Returns memory usage constraints for the layer.

Returns:

The memory usage constraints for the layer.

setMaxMemorySize

public void setMaxMemorySize(long size)

Set memory usage constraints for the layer. The specified limit is not exact,
but should be relatively close to the actual memory usage of the layer.
If specific view requires more data than specified limit, then lower LOD levels
of the models are used. The default is 40MB.

Parameters:

size - The memory limit in bytes.

getLODResolutionFactor

public float getLODResolutionFactor()

Returns relative model LOD resolution.

Returns:

The relative model LOD resolution.

setLODResolutionFactor

public void setLODResolutionFactor(float factor)

Set relative model LOD resolution. Higher values than 1 result in higher details
(but slower performance and higher memory usage), while lower values give better
performance but lower quality. The default is 1.

Parameters:

factor - The relative LOD resolution factor.

isUpdateInProgress

public boolean isUpdateInProgress()

Description copied from class: Layer

Tests whether this layer is being currently updated.

Overrides:

isUpdateInProgress in class Layer

Returns:

True when the layer is being updated or false when the layer is in steady state.

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

Overrides:

swigGetClassName in class Layer

Returns:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

Overrides:

swigGetDirectorObject in class Layer

Returns:

The connected director object or null if director is not connected.
