Abstract

Process for generating the image of a 3-dimensional rigid body on a computer screen. a system of 3-dimensional space coordinates is defined in the space in which the body moves. Software, which defines the way in which the body appears when viewed at a given angle and distance to one of the coordinate planes is established and the coordinates are determined in the coordinates system of a number of points. The coordinates of the points of the rigid body and the software are transmitted to the computer, which creates the image of the rigid body when in any specific position in space and viewed at any specific angle. The points of the rigid body, the coordinates of which are determined, may be in the number of three. The rigid body may have symmetries and the points thereof, the coordinates of which are determined, may be less than three.
