Constructor Details

Geometry

public Geometry(ConstAaBox bounds)

Instantiate a geometry with the specified bounding box.

Parameters:

bounds - the desired bounding box (not null, unaffected)

Method Details

countLods

public int countLods()

Return the number of levels of detail. The geometry is unaffected. (native member: mLODs)

Returns:

the count (≥0)

getBounds

public ConstAaBox getBounds()

Access the bounding box. The geometry is unaffected. (native field: mBounds)

Returns:

a new JVM object the pre-existing native object assigned

getLod

public ConstLod getLod(int index)

Access the specified level of detail. The geometry is unaffected. (native field: mLODs)

Parameters:

index - the index of the level (≥0)

Returns:

a new JVM object with the pre-existing native object assigned

getLod

public ConstLod getLod(Vec3Arg cameraPosition,
 ConstAaBox worldSpaceBounds,
 float lodScaleSq)

Access the appropriate level of detail for the specified conditions. The geometry is unaffected. (native method: GetLOD)

Parameters:

cameraPosition - the location of the camera (not null, unaffected)

worldSpaceBounds - bounds for this geometry (in system coordinates, not null, unaffected)

lodScaleSq - the squared scale of the model matrix

Returns:

a pre-existing LOD

getLods

public ConstLod[] getLods()

Access all the levels of detail. The geometry is unaffected.

Returns:

a new array of new JVM objects with pre-existing native objects assigned

getRefCount

public int getRefCount()

Count the active references to the native Geometry. The geometry is unaffected.

Specified by:

getRefCount in interface RefTarget

Returns:

the count (≥0)

setEmbedded

public void setEmbedded()

Mark the native Geometry as embedded.

Specified by:

setEmbedded in interface RefTarget

toRef

public Ref toRef()

Create a counted reference to the native Geometry.

Specified by:

toRef in interface RefTarget

Returns:

a new JVM object with a new native object assigned
