Abstract

Provided are a method and apparatus rendering three-dimensional (3D) graphic data. The method includes eliminating at least one of a plurality of processes for rendering the three-dimensional (3D) graphic data in consideration of a rendering environment of the 3D graphic data and a state of power of a system rendering the 3D graphic data, generating a rendering function which performs the remaining processes after the at least one process is eliminated and rendering the 3D graphic data using the generated rendering function.

Claims

1. A method of rendering three-dimensional (3D) graphic data comprising:

eliminating at least one of a plurality of processes for rendering the three-dimensional (3D) graphic data in consideration of a rendering environment of the 3D graphic data;

generating a rendering function which performs the remaining processes after the at least one process is eliminated; and

rendering by way of a processro the 3D graphic data using the generated rendering function,

wherein the eliminating of the at least one of the processes comprises sequentially eliminating at least one rendering option of a plurality of rendering options in order of the rendering options related to effect on image quality represented by the 3D graphic data in consideration of the rendering environment of the 3D graphic data, each of the plurality of rendering options rendering the 3D graphic data using a different rendering technique,

wherein the at least one rendering option is sequentially eliminated by a number of the rendering options corresponding to a value representing the rendering environment of the 3D graphic data, in order from a rendering option having a least effect on the image quality to another rendering option having a most effect on the image quality.

2. The method of claim 1, wherein the rendering environment comprises a state of power of a system rendering the 3D graphic data.

3. The method of claim 2, wherein the eliminating of the at least one of the processes comprises:

analyzing the state of power of the system;

designating at least one of the processes based on the analyzed state of power of the system and with reference to a corresponding relationship between a plurality of power states and the processes, respectively; and

eliminating the designated at least one of the processes.

4. The method of claim 3, wherein, if the current state of power of the system is represented by the remaining power of the system, which can be currently used, the corresponding relationship is established between the states of power listed in order of the highest to lowest remaining power and the processes listed in order of least to most effect on the image quality, which is represented by the 3D graphic data, respectively.

5. The method of claim 1, wherein the rendering environment comprises at least one of a current distance between an object, represented by the 3D graphic data, and a camera and a current area occupied by the object on a screen.

6. The method of claim 5, wherein the eliminating of the at least one of the processes comprises:

analyzing at least one of the current distance and the current area;

designating at least one of the processes based on a value calculated using the analysis result and with reference to the corresponding relationship between a plurality of values, which are determined according to at least one of the current distance and the current area, and the processes, respectively; and

eliminating the designated at least one of the processes.

7. The method of claim 6, wherein the value is increased as the distance decreases or the area increases, and the corresponding relationship established between the values listed from highest to lowest and the processes listed in order of least to most effect on the image quality, which is represented by the 3D graphic data, respectively.

8. The method of claim 1, further comprising:

analyzing characteristics of the 3D graphic data; and

selecting the processes with reference to the analyzed characteristics of the 3D graphic data,

wherein the eliminating of the at least one of the processes comprises eliminating the at least one of the selected processes in consideration of the rendering environment.

9. The method of claim 1, wherein the generating of the rendering function comprises:

extracting one or more code blocks corresponding to predetermined functions for rendering the 3D graphic data, which are performed in the remaining processes; and

generating the rendering function by combining the extracted code blocks.

10. The method of claim 1, wherein, in the rendering of the 3D graphic data, no more than a predetermined number of frames of the 3D graphic data are rendered over a predetermined period of time.

11. The method of claim 10, wherein the rendering of the 3D graphic data comprises:

measuring time taken to render a current frame;

calculating a delay time which is a difference between a rendering time of a frame, determined based on the predetermined period of time and the predetermined number of frames, and the measured time; and

rendering a next frame if the calculated delay time is a negative number and waiting the calculated delay time and then rendering the next frame if the calculated delay time is not the negative number.

12. At least one non-transitory medium comprising computer readable code to control at least one processing element to implement the method of any one of claims 1 though 11.

13. An apparatus rendering three-dimensional (3D) graphic data comprising:

a processor to control one or more processor executable units a setting unit eliminating at least one of a plurality of processes for rendering 3D graphic data in consideration of a rendering environment of the 3D graphic data;

a function generation unit generating a rendering function which performs the remaining processes after the at least one process is eliminated; and

a rendering unit rendering the 3D graphic data using the generated rendering function

wherein the setting unit sequentially eliminates at least one rendering option of a plurality of rendering options in order of the rendering options related to effect on image quality represented by the 3D graphic data in consideration of the rendering environment of the 3D graphic data, each of the plurality of rendering options rendering the 3D graphic data using a different rendering technique

wherein the at least one rendering option is sequentially eliminated by a number of the rendering options corresponding to a value representing the rendering environment of the 3D graphic data, in order from a rendering option having a least effect on the image quality to another rendering option having a most effect on the image quality.

14. The apparatus of claim 13, wherein the setting unit comprises:

a rendering environment analysis unit analyzing the rendering environment of the 3D graphic data;

a designation unit designating at least one of the processes based on a state of the analyzed rendering environment of the 3D graphic data and with reference to a corresponding relationship between a plurality of states of the rendering environment and the processes, respectively; and

eliminating the designated at least one of the processes.

15. The apparatus of claim 13, wherein the rendering environment comprises a state of power of a system rendering the 3D graphic data.

16. The apparatus of claim 13, wherein the rendering environment comprises at least one of a current distance between an object, represented by the 3D graphic data, and a camera and a current area occupied by the object on a screen.

17. The apparatus of claim 13, further comprising a data analysis unit analyzing characteristics of the 3D graphic data and selecting the processes with reference to the analyzed characteristics of the 3D graphic data.
