Class CompressedGeometryHeader
- java.lang.Object
-
- javax.media.j3d.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.

majorVersionNumber
public int majorVersionNumber
Deprecated.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:
Canvas3D.queryProperties()
-
minorVersionNumber
public int minorVersionNumber
Deprecated.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:
Canvas3D.queryProperties()
-
minorMinorVersionNumber
public int minorMinorVersionNumber
Deprecated.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:
Canvas3D.queryProperties()
-
bufferType
public int bufferType
Deprecated.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 bystart
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 thestart
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
