Class CoordinateUtils

  • public class CoordinateUtils
extends java.lang.Object
    A utility class that can be used to modify coordinate values of an item of geometry.

    The utility class may be used as either a single shared instance or as a normal class. Sometimes you have a lot of different code all wanting to do similar modifications simultaneously and so having a single static-only class with synchronised methods would be very bad for performance.

      • translate

        public void translate​(float[] coords,
                      int numCoords,
                      float x,
                      float y,
                      float z)
        Translate, in place, the coordintes by the given amount in each direction. It assumes that the array has the coordinate values as a flat array of values.
        Parameters:
        coords - The source coordinate array to copy
        numCoords - The number of valid coordinates in the array
        x - The amount to translate in the x axis
        y - The amount to translate in the y ayis
        z - The amount to translate in the z azis
