1 . A holographic content providing method based on distributed processing performed by a holographic content providing apparatus, the method comprising:
generating holographic content by capturing a real object, a virtual object and light information; editing the holographic content using object data of the generated holographic content; advance-visualizing a result of three-dimensional (3D) rendering the holographic content; and converting 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.

2 . The method of claim 1 , wherein the generating generates the holographic content in a successive for per temporal frame using the real object corresponding to a foreground or background, the virtual object corresponding to 3D model data and the lighting information on the virtual object.

3 . The method of claim 1 , wherein the editing divides the holographic content into small parts with a certain size to use distributed processing.

4 . The method of claim 1 , wherein the editing edits fringe information on order information on the object data in a format of the object data.

5 . The method of claim 1 , wherein the editing edits the holographic content to have an arrangement-based spherical form in view of bandwidth optimization and viewpoint shift of the object data.

6 . The method of claim 1 , wherein the editing edits the holographic content to enable an interaction with a user by applying a numerical reconstruction technique to the object data.

7 . The method of claim 1 , wherein the advance-visualizing conducts 3D rendering in view of light wave distribution of the edited holographic content.

8 . The method of claim 7 , wherein the advance-visualizing advance-visualizes the 3D rendered holographic content in an optical reconstruction simulation method based on numerical reconstruction.

9 . The method of claim 3 , wherein the converting integrates the divided small parts with the certain size of the holographic content into unitary holographic content.

10 . 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.

11 . The method of claim 10 , wherein the displaying displays the holographic content through temporal multiplexing or spatial multiplexing by adjusting an arrangement of a flexible multiple light modulator.

12 . The method of claim 10 , wherein the displaying displays the holographic content by matching a space for presenting the displayed holographic content and a user gesture recognition space to conduct an interaction between the holographic content and a user.

13 . The method of claim 10 , wherein the feeding back compares the holographic content reconstructed in the optical method by the display apparatus with holographic content advance-visualized in a numerical manner by the holographic content providing apparatus.

14 . 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.

15 . The holographic content providing apparatus of claim 14 , wherein the edition unit divides the holographic content into small parts with a certain size to use distributed processing, and edits fringe information on order information on the object data in a format of the object data.

16 . The holographic content providing apparatus of claim 14 , wherein the edition unit edits the holographic content to have an arrangement-based spherical form in view of bandwidth optimization and viewpoint shift of the object data.

17 . The holographic content providing apparatus of claim 14 , wherein the edition unit edits the holographic content to enable an interaction with a user by applying a numerical reconstruction technique to the object data.

18 . The holographic content providing apparatus of claim 14 , wherein the advance visualization unit conducts 3D rendering in view of light wave distribution of the edited holographic content, and advance-visualizes the 3D rendered holographic content in an optical reconstruction simulation method based on numerical reconstruction.
