Method Detail

toTriangleArrays

Shape3D[] toTriangleArrays(CompressedGeometryRetained cgr)

Decompress the given compressed geometry.

Parameters:

cgr - CompressedGeometryRetained object with compressed geometry

Returns:

an array of Shape3D with TriangleArray geometry if compressed data contains triangles; otherwise, Shape3D array containing PointArray or LineStripArray geometry

See Also:

CompressedGeometry, GeometryDecompressor

toTriangleStripArrays

Shape3D[] toTriangleStripArrays(CompressedGeometryRetained cgr)

Decompress the given compressed geometry.

Parameters:

cgr - CompressedGeometryRetained object with compressed geometry

Returns:

an array of Shape3D with TriangleStripArray geometry if compressed data contains triangles; otherwise, Shape3D array containing PointArray or LineStripArray geometry

See Also:

CompressedGeometry, GeometryDecompressor

toStripAndFanArrays

Shape3D[] toStripAndFanArrays(CompressedGeometryRetained cgr)

Decompress the given compressed geometry.

Parameters:

cgr - CompressedGeometryRetained object with compressed geometry

Returns:

an array of Shape3D with TriangleStripArray and TriangleFanArray geometry if compressed data contains triangles; otherwise, Shape3D array containing PointArray or LineStripArray geometry

See Also:

CompressedGeometry, GeometryDecompressor

toStripAndTriangleArrays

Shape3D[] toStripAndTriangleArrays(CompressedGeometryRetained cgr)

Decompress the given compressed geometry.

Parameters:

cgr - CompressedGeometryRetained object with compressed geometry

Returns:

an array of Shape3D with TriangleStripArray and TriangleArray geometry if compressed data contains triangles; otherwise, Shape3D array containing PointArray or LineStripArray geometry

See Also:

CompressedGeometry, GeometryDecompressor

decompress

private Shape3D[] decompress(CompressedGeometryRetained cgr,
                   int triOutputType)

Decompress the data contained in a CompressedGeometryRetained and return an array of Shape3D objects using the specified triangle output type. The triangle output type is ignored if the compressed data contains points or lines.

outputVertexFormat

void outputVertexFormat(boolean bundlingNorm,
                      boolean bundlingColor,
                      boolean doingAlpha)

Initialize the vertex output list based on the vertex format provided by the SetState decompression command.

Specified by:

outputVertexFormat in class GeometryDecompressor

Parameters:

bundlingNorm - true indicates normals are bundled with vertices

bundlingColor - true indicates colors are bundled with vertices

doingAlpha - true indicates alpha values are bundled with vertices

outputVertex

void outputVertex(Point3f position,
                Vector3f normal,
                Color4f color,
                int vertexReplaceCode)

Add a new decompressed vertex to the current list.

Specified by:

outputVertex in class GeometryDecompressor

Parameters:

position - The coordinates of the vertex.

normal - The normal bundled with the vertex. May be null.

color - The color bundled with the vertex. May be null. Alpha may be present.

vertexReplaceCode - Specifies the generalized strip flag that is bundled with each vertex.

See Also:

GeneralizedStripFlags, CompressedGeometryHeader

outputColor

void outputColor(Color4f color)

Create a Shape3D using the current color for both the ambient and diffuse material colors, then start a new vertex list for the new color. The outputColor() method is never called if colors are bundled with each vertex in the compressed buffer.

Specified by:

outputColor in class GeometryDecompressor

Parameters:

color - The current global color.

outputNormal

void outputNormal(Vector3f normal)

Set the current normal that will be copied to each succeeding vertex output by the decompressor. The per-vertex copy is needed since in Java 3D a normal is always associated with a vertex. This method is never called if normals are bundled with each vertex in the compressed buffer.

Specified by:

outputNormal in class GeometryDecompressor

Parameters:

normal - The current global normal.

addShape3D

private void addShape3D()

Create a Shape3D object of the desired type from the current vertex list. Apply the current color, if non-null, as a Material attribute.
