public static class CompressedGeometryData.Header
extends java.lang.Object
All instance data is declared public and no get or set methods are provided.
Modifier and Type | Field | Description |
---|---|---|
static int |
ALPHA_IN_BUFFER |
bufferDataPresent: bit indicating that alpha information is
bundled with the vertices in the compressed geometry buffer.
|
int |
bufferDataPresent |
Contains bits indicating what data is bundled with the vertices in the
compressed geometry buffer.
|
int |
bufferType |
Describes the type of data in the compressed geometry buffer.
|
static int |
COLOR_IN_BUFFER |
bufferDataPresent: bit indicating that RGB color information is
bundled with the vertices in the compressed geometry buffer.
|
static int |
LINE_BUFFER |
bufferType: compressed geometry is made up of line segments.
|
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.
|
int |
majorVersionNumber |
The major version number for the compressed geometry format that
was used to compress the geometry.
|
int |
minorMinorVersionNumber |
The minor-minor version number for the compressed geometry format
that was used to compress the geometry.
|
int |
minorVersionNumber |
The minor version number for the compressed geometry format that
was used to compress the geometry.
|
static int |
NORMAL_IN_BUFFER |
bufferDataPresent: bit indicating that normal information is
bundled with the vertices in the compressed geometry buffer.
|
static int |
POINT_BUFFER |
bufferType: compressed geometry is made up of individual points.
|
int |
size |
Size of the compressed geometry in bytes.
|
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.
|
static int |
TRIANGLE_BUFFER |
bufferType: compressed geometry is made up of triangles.
|
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.
|
Constructor | Description |

toString() |
Returns a String describing the contents of the
Header object.

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.
