Holographic content providing method, and holographic content providing apparatus and display apparatus using the method

A holographic content providing method performed by a display apparatus, the method comprising:

• displaying holographic content optimized for a data format of the display apparatus, received from a holographic content providing apparatus, in an optical method;
• and
• feeding back a result of displaying the holographic content to the holographic content providing apparatus,
• wherein the holographic content providing apparatus converts a data format of object data of the holographic content based on distributed processing and provides the converted holographic content.

A holographic content providing apparatus comprising:

• a generation unit to generate holographic content by capturing a real object, a virtual object and light information;
• an edition unit to edit the holographic content using object data of the generated holographic content;
• an advance visualization unit to advance-visualize a result of three-dimensional (3D) rendering the holographic content;
• and
• a conversion unit to convert a data format of the object data of the visualized holographic content corresponding to a display format of a display apparatus,
• wherein the display apparatus displays the holographic content of which the data format of the object data is converted in an optical method and feeds back a result of displaying the holographic content.

A display apparatus comprising:

• a display unit to display holographic content optimized for a data format of the display apparatus, received from a holographic content providing apparatus, in an optical method;
• and
• a feedback unit to feed back a result of displaying the holographic content to the holographic content providing apparatus,
• wherein the holographic content providing apparatus optimizes a data format of object data of the holographic content based on distributed processing according to the data format of the display apparatus, and provides the optimized holographic content.
