• LINE_BUFFER

  public static final int LINE_BUFFER

  bufferType: compressed geometry is made up of line segments.

  See Also:

  • Constant Field Values

• TRIANGLE_BUFFER

  public static final int TRIANGLE_BUFFER

  bufferType: compressed geometry is made up of triangles.

  See Also:

  • Constant Field Values

• NORMAL_IN_BUFFER

  public static final int NORMAL_IN_BUFFER

  bufferDataPresent: bit indicating that normal information is bundled with the vertices in the compressed geometry buffer.

  • Constant Field Values

• COLOR_IN_BUFFER

  public static final int COLOR_IN_BUFFER

  bufferDataPresent: bit indicating that RGB color information is bundled with the vertices in the compressed geometry buffer.

  See Also:

  • Constant Field Values

• ALPHA_IN_BUFFER

  public static final int ALPHA_IN_BUFFER

  bufferDataPresent: bit indicating that alpha information is bundled with the vertices in the compressed geometry buffer.

  See Also:

  • Constant Field Values

• majorVersionNumber

  public int majorVersionNumber

  The major version number for the compressed geometry format that was used to compress the geometry. If the version number of compressed geometry is incompatible with the supported version of compressed geometry in the current version of Java 3D, the compressed geometry obejct will not be rendered.

  See Also:

  • invalid reference

    Canvas3D#queryProperties

• minorVersionNumber

  public int minorVersionNumber

  The minor version number for the compressed geometry format that was used to compress the geometry. If the version number of compressed geometry is incompatible with the supported version of compressed geometry in the current version of Java 3D, the compressed geometry obejct will not be rendered.

  See Also:

  • invalid reference

    Canvas3D#queryProperties

• minorMinorVersionNumber

  public int minorMinorVersionNumber

  The minor-minor version number for the compressed geometry format that was used to compress the geometry. If the version number of compressed geometry is incompatible with the supported version of compressed geometry in the current version of Java 3D, the compressed geometry obejct will not be rendered.

  See Also:

  • invalid reference

    Canvas3D#queryProperties

• bufferType

  public int bufferType

  Describes the type of data in the compressed geometry buffer. Only one type may be present in any given compressed geometry buffer.

• bufferDataPresent

  public int bufferDataPresent

  Contains bits indicating what data is bundled with the vertices in the compressed geometry buffer. If this data is not present (e.g. color) then this info will be inherited from the Appearance node.

• size

  public int size

  Size of the compressed geometry in bytes.

• start

  public int start

  Offset in bytes of the start of the compressed geometry from the beginning of the compressed geometry byte array passed to the CompressedGeometryData constructor.

  If the CompressedGeometryData is created with reference access semantics, then this allow external compressors or file readers to embed several blocks of compressed geometry in a single large byte array, possibly interspersed with metadata that is not specific to Java 3D, without having to copy each block to a separate byte array.

  If the CompressedGeometryData is created with copy access semantics, then size bytes of compressed geometry data are copied from the offset indicated by start instead of copying the entire byte array. The getCompressedGeometry() method will return only the bytes used to construct the object, and the getCompressedGeometryHeader() method will return a header with the start field set to 0.

• lowerBound

  public javax.vecmath.Point3d lowerBound

  A point that defines the lower bound of the x, y, and z components for all positions in the compressed geometry buffer. If null, a lower bound of (-1,-1,-1) is assumed. Java 3D will use this information to construct a bounding box around compressed geometry objects that are used in nodes for which the auto compute bounds flag is true. The default value for this point is null.

• upperBound

  public javax.vecmath.Point3d upperBound

  A point that defines the upper bound of the x, y, and z components for all positions in the compressed geometry buffer. If null, an upper bound of (1,1,1) is assumed. Java 3D will use this information to construct a bounding box around compressed geometry objects that are used in nodes for which the auto compute bounds flag is true. The default value for this point is null.
