Class Point3d

java.lang.Object
com.ijurnove.cpu3d.Point3d
All Implemented Interfaces:
Rotatable, Scalable, Translatable
public class Point3d extends Object implements Translatable, Rotatable, Scalable
A Point3d is a specific point in 3D space. Point3d objects store two different positions as Matrixes, one for its position in 3D space, and one for its position on the screen.

  • Field Details

    • ORIGIN

      public static final Point3d ORIGIN
      A Point3d at (0, 0, 0)

  • Constructor Details

    • Point3d

      public Point3d(Matrix pos)
      Constructs a Point3d at the coordinates specified in a given Matrix. The Matrix should have 1 column and 3 or 4 rows. Row 1 is the X position, row 2 is the Y, and row 3 is the Z.
      Parameters:
      pos - the Matrix representing the constructed Point3d's coordinates

    • Point3d

      public Point3d(double x, double y, double z)
      Constructs a new Point3d at the given X, Y, and Z.
      Parameters:
      x - the X position of the constructed Point3d
      y - the Y position of the constructed Point3d
      z - the Z position of the constructed Point3d
