Class CompressedGeometryHeader


  • public class CompressedGeometryHeader
    extends java.lang.Object
    Deprecated.
    As of Java 3D version 1.4.
    The CompressedGeometrHeader object is used in conjunction with the CompressedGeometry object. The CompressedGeometrHeader object contains information specific to the compressed geometry stored in CompressedGeometry NodeComponent object. This information is used to aid the decompression of the compressed geometry.

    All instance data is declared public and no get or set methods are provided.

      • 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
        Deprecated.
        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
        Deprecated.
        Size of the compressed geometry in bytes.
      • start

        public int start
        Deprecated.
        Offset in bytes of the start of the compressed geometry from the beginning of the compressed geometry byte array passed to the CompressedGeometry constructor.

        If the CompressedGeometry 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 CompressedGeometry 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
        Deprecated.
        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.
        Since:
        Java 3D 1.2
      • upperBound

        public javax.vecmath.Point3d upperBound
        Deprecated.
        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.
        Since:
        Java 3D 1.2
