Controls for drawing images on computer displays

In an interactive computer-controlled display system having a processor, a memory means, a display screen coupled to said processor, a cursor control device coupled to said processor for interactively positioning a cursor on said display screen, and a signal generation device, a process for generating and manipulating a wall object on said display screen comprising the steps of:

• configuring the generation of said wall object by selecting and setting a plurality of configuration parameters;
• receiving a wall point;
• drawing a portion of said wall object on said display screen, said portion of said wall object comprising a first line and a second line each drawn between said wall point and the position of said cursor, said first line and said second line being parallel to each other and separated by a previously configured distance;
• repeating said receiving step and said drawing step until a termination signal is received from said signal generation device after said signal generation device is activated by a user;
• modifying said wall object as specified by said configuration parameters.
