3d holographic display and holographic object formation

A computer program product for creating a 3D (three-dimensional) holographic display in a device having a camera, holographic projectors and a display surface, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• tracking by the camera an interactive device over the display;
• determining by the camera a distance from the interactive device to the display;
• responsive to an action by the interactive device, visually displaying by the holographic projectors a unit holographic object proximate to the interactive device and spaced from the display surface by the distance determined by the camera;
• responsive to one or more additional actions by the interactive device, visually displaying by the holographic projectors additional unit holographic objects proximate to the unit holographic object so as to be visually displaying a plurality of unit holographic objects including the unit holographic object;
• accumulating by the holographic projectors the plurality of unit holographic objects proximate to the display surface;
• and
• determining an amount of accumulated unit holographic objects visually displayed by the holographic projectors until a resultant shape of holographic objects is formed.

A system for creating a 3D (three-dimensional) holographic display comprising:

• a device having a camera, holographic projectors and a display surface;
• a non-transitory storage medium that stores instructions;
• and
• a processor that executes the instructions to perform:
• tracking by the camera an interactive device over the display;
• determining by the camera a distance from the interactive device to the display;
• responsive to an action by the interactive device, visually displaying by the holographic projectors a unit holographic object proximate to the interactive device and spaced from the display surface by the distance determined by the camera;
• responsive to one or more additional actions by the interactive device, visually displaying by the holographic projectors additional unit holographic objects proximate to the unit holographic object so as to be visually displaying a plurality of unit holographic objects including the unit holographic object;
• accumulating by the holographic projectors the plurality of unit holographic objects proximate to the display surface;
• and
