public final class VolumesF extends Object

Functions over volumes.

These functions operate using the concepts of minimum-x, maximum-x, minimum-y, maximum-y, minimum-z, maximum-z, edges. It is up to individual applications to assign meaning to these edges such as "left" for minimum-x, "top" for minimum-y, or "far" for minimum-z.

    • create

      public static VolumeF create(float x, float y, float z, float size_x, float size_y, float size_z)
      Create a volume of size (size_x, size_y, size_z) placing the minimum corner at (x, y, z).
      Parameters:
      x - The X value of the minimum corner
      y - The Y value of the minimum corner
      z - The Z value of the minimum corner
      size_x - The size of the volume on the X axis
      size_y - The size of the volume on the Y axis
      size_z - The size of the volume on the Z axis
      Returns:
      A volume

    • contains

      public static boolean contains(VolumeF a, VolumeF b)

      Determine whether or not one volume contains another.

      Containing is reflexive: contains(a, a) == true.

      Containing is transitive: contains(a, b) → contains(b, c) → contains(a, c).

      Containing is not necessarily symmetric.

      Parameters:
      a - Volume A
      b - Volume B
      Returns:
      true iff a contains b
