Patent ID: 7701455

Claim:
Method of displaying a geometric primitive with a desired brightness level in actual 3D space in a volumetric 3D display, said geometric primitive being a line or a surface, the volumetric 3D display comprising spatially distributed display elements for displaying volumetric 3D images, the method including: (1) a step of determining a minimum number, Nge_op, of display elements required to display said geometric primitive at full brightness, Br_op; (2) a step of determining a desired number, Nge, of display elements to display said geometric primitive at the desired brightness level based on the following relation: ( Nge/Nge — op )×( Bge/Bge — f )= Br/Br — op, wherein Br representing the desired brightness level of said geometric primitive, Bge_f representing full brightness level of said display element, Bge representing brightness level of said display element to be used to render said geometric primitive; (3) a step of rendering said geometric primitive with said desired number of display elements.
