• originCoordinates: By default, the origin of coordinates is placed in the center of the screen, but it is possible to place it in another point of the screen. 2dPosition property. Time-dependent.
  
  
• position: Position of the center of the stimulus relative to the origin of coordinates. X increases from left to right and Y increases from bottom to top. The angles are measured counterclockwise from the X-axis. 2dPosition property. Time-dependent.
  
  
  
• rotation: The angle of rotation of the stimulus (both the shape and its content). Measured counterclockwise. Angle property. Time-dependent.
