Representation of three-dimensional bodies on computer screens and games involving such representations

Process for representing the interaction between at least two real bodies, which comprises:

• generating an image of a first real body;
• generating an image of a second real body;
• and
• modifying or integrating the software relative to said first body to cause the image thereof to react to the presence within a certain distance, and, optionally, in a certain direction, of the image of said second body.

Process for representing the interaction between a real body and a virtual body, which comprises:

• providing a software which creates a virtual body;
• generating an image of a real body;
• and
• modifying or integrating said software to cause said virtual body to react to the presence of said image within a certain distance, and, optionally, in a certain direction.

Process for representing the interaction between real points, defined in space, and a virtual body or an image, which comprises:

• I) defining a set of 3-dimensional space coordinates in the space in which the body moves, and storing in the computer's memory the definition of said set;
• B) associating said real points to points of the virtual body or the image;
• III) modifying the software which controls the virtual body or the image, insofar as necessary, to react to the motion of said real points;
• IV) determining the coordinates of said real points with respect to said space coordinates set;
• and
• V) transmitting to the computer said coordinates of said real points.
