Class HiResCoord

    java.lang.Object
      javax.media.j3d.HiResCoord

    public class HiResCoord

extends java.lang.Object

The HiResCoord object specifies the location of scene components within the Virtual Universe. The coordinates of all scene graph objects are relative to the HiResCoord of the Locale in which they are contained.

The HiResCoord defines a point using a set of three high-resolution coordinates, each of which consists of three two's-complement fixed-point numbers. Each high-resolution number consists of 256 total bits with a binary point at bit 128, or between the integers at index 3 and 4. A high-resolution coordinate of 1.0 is defined to be exactly 1 meter. This coordinate system is sufficient to describe a universe in excess of several billion light years across, yet still define objects smaller than a proton.

Java 3D uses integer arrays of length eight to define or extract a single 256-bit coordinate value. Java 3D interprets the integer at index 0 as the 32 most-significant bits and the integer at index 7 as the 32 least-significant bits.
