    • Rayd

      public Rayd(Vector3d origin, Vector3d direction)
      Constructor, sets the starting position of the Rayd and the direction.
      Parameters:
      origin - The starting position
      direction - The direction
  • Method Details

    • cpy

      public Rayd cpy()
      Returns:
      a copy of this Rayd.
    • getEndPoint

      @Deprecated public Vector3d getEndPoint(float distance)
      Deprecated.
      Use getEndPoint(Vector3d, float) instead. Returns the endpoint given the distance. This is calculated as startpoint + distance * direction.
      Parameters:
      distance - The distance from the end point to the start point.
      Returns:
      The end point
    • getEndPoint

      public Vector3d getEndPoint(Vector3d out, float distance)
      Returns the endpoint given the distance. This is calculated as startpoint + distance * direction.
      Parameters:
      out - The vector to set to the result
      distance - The distance from the end point to the start point.
      Returns:
      The out param
    • mul

      public Rayd mul(Matrix4d matrix)
      Multiplies the Rayd by the given matrix. Use this to transform a Rayd into another coordinate system.
      Parameters:
      matrix - The matrix
      Returns:
      This Rayd for chaining.

      Parameters:
      origin - The starting position
      direction - The direction
      Returns:
      this Rayd for chaining
    • set

      public Rayd set(float x, float y, float z, float dx, float dy, float dz)
