System and method for displaying 3-dimension map using texture mapping

1. A display system, comprising:

a texture maintenance unit maintaining a texture generated based on a characteristic of an object;

a texture selection unit selecting a texture based on an object to be displayed; and

a texture application unit repeatedly applying the selected texture to at least a portion of a three-dimensional (3D) structure corresponding to the object to be displayed in which the portion has a first width and a first length,

wherein the texture application unit repeatedly applying the selected texture is applying a number of same size textures calculated based on a first ratio, which is an integer obtained by truncating decimals according to the first width of the portion and a second width of the selected texture, and a second ratio, which is an integer obtained by truncating decimals according to the first length of the portion and a second length of the selected texture, each of the repeatedly applied same size textures is fully displayed on an external surface of the portion of the 3D structure.

2. The display system of claim 1 , wherein the external surface corresponds to the object to be displayed, and the texture application unit comprises:

a texture application confirmation unit confirming a number of applications of the selected texture based on width and length data of the selected texture and the external surface texture; and

an application unit connecting the same number of the selected texture as the confirmed number of applications, and applying the connected texture as repeating same size textures to the external surface texture,

wherein the texture application confirmation unit confirms the number by processing the length data.

3. The display system of claim 2 , wherein the texture application confirmation unit comprises:

a row confirmation unit confirming a number of rows to be applied based on the first ratio of a width of the external surface texture to the width of the selected texture;

a column confirmation unit confirming a number of columns to be applied based on the second ratio of a length of the external surface texture to the length of the selected texture; and

a confirmation unit confirming the number of applications based on the number of rows and the number of columns.

4. The display system of claim 3 , wherein the application unit connects the selected texture in matrix form with the number of rows and the number of columns confirmed by the texture application confirmation unit.

5. The display system of claim 1 , wherein an unapplied portion of the external surface texture is in a predetermined color.

6. The display system of claim 1 , further comprising:

a display unit displaying the 3D texture where the selected texture is applied on a map screen.

7. The display system of claim 1 , wherein the object includes an artificial structure to be displayed on a 3D map, and the characteristic of the object includes a characteristic of an external surface of the artificial structure.

8. The display system of claim 7 , wherein the selected texture includes 3D linear data of the artificial structure, and the repeatedly applied same size textures represents an external appearance of the artificial structure based on the 3D linear data.

9. A display method, comprising:

maintaining, by a display system, a texture generated based on a characteristic of an object;

selecting, by the display system, a texture based on an object to be displayed; and

repeatedly applying, by the display system, the selected structure to at least a portion of a 3D object to be displayed in which the portion has a first width and a first length,

wherein the repeatedly applying the selected texture is applying a number of same size textures calculated based on a first ratio, which is an integer obtained by truncating decimals according to the first width of the portion and a second width of the selected texture, and a second ratio, which is an integer obtained by truncating decimals according to the first length of the portion and a second length of the selected texture, each of the repeatedly applied same size textures is fully displayed on an external surface of the portion of the 3D structure.

10. The display method of claim 9 , wherein the external surface corresponds to the object to be displayed, and the applying comprises:

confirming a number of applications of the selected texture based on width and length data of the selected texture and the external surface texture; and

connecting the same number of the selected texture as the confirmed number of applications, and applying the connected texture as repeating same size textures to the external surface texture.

11. The display method of claim 10 , wherein the confirming comprises:

confirming a number of rows to be applied based on the first ratio of a width of the external surface texture to the width of the selected texture;

confirming a number of columns to be applied based on the second ratio of a length of the external surface texture to the length of the selected texture; and

confirming the number of applications based on the number of rows and the number of columns.

12. The display method of claim 11 , wherein the connecting and the applying comprises:

connecting the selected texture in matrix form with the number of rows and the number of columns.

13. The display method of claim 9 , further comprising:

displaying the selected texture as repeating same size textures on a map screen.

14. The display method of claim 9 , wherein the object includes an artificial structure to be displayed on a 3D map, and the characteristic of the object includes a characteristic of an external surface of the artificial structure.

15. The display method of claim 14 , wherein the selected texture includes 3D linear data of the artificial structure, and the repeatedly applied same size textures represent an external appearance of the artificial structure based on the 3D linear data.

16. A non-transitory computer-readable storage medium storing a program for implementing the method according to claim 9 .
