Image processing method
View Patent ↗An object surface is rendered by not only grid lines indicating a slope in the surface of an object, but also by moving objects which move over the object surface with a speed responsive to the slope angle on the object surface, thereby enabling a player to refer to the grid lines and to the movement of a moving object, so as to visually perceive minute slopes and bumps in the object surface.
1. An image display method comprising:
overlaying and displaying grid lines having a plurality of line segments on an object surface,
wherein the grid lines are displayed in accordance with a viewing direction of the object surface specified by a player; and
displaying a first moving object on a first line segment of the grid lines and concurrently displaying a second moving object on a second line segment of the grid lines,
wherein a slope angle of the first line segment is different that a slope angle of the second line segment, and
wherein a speed of movement of the first moving object is different than a speed of movement of the second moving object.
2. The image display method according to claim 1 , wherein the slope angle of the first line segment is greater than the slope angle of the second line segment.
3. The image display method according to claim 2 , wherein the speed of movement of the first moving object is greater than the speed of movement of the second moving object.
4. The image display method according to claim 1 , wherein the speed of movement of the first moving object is directly proportional to a slope angle of the first line segment.
5. The image display method according to claim 1 , wherein the color of the first line segment is different than the color of the second line segment.
6. The image display method according to claim 1 , wherein a texture is mapped onto the first moving object.
7. An image display method comprising:
overlaying and displaying grid lines having a plurality of line segments on an object surface,
wherein the rid lines are displayed in accordance with a viewing direction specified by a player; and
displaying at least one moving object on at least one line segment of the grid lines,
wherein the moving object only moves on the line segment.
8. The image display method according to claim 7 , wherein a speed of movement of the at least one moving object is directly proportional to a slope of the at least one line segment.
9. The image display method according to claim 7 , wherein a speed of movement of the at least one moving object is directly proportional to a height of the at least one line segment.
10. The image display method according to claim 7 , wherein a speed of movement of the at least one moving object is indirectly proportional to a length of the at least one line segment.
11. The image display method according to claim 7 , wherein the at least one line segment has a first end and a second end, wherein the first end has a first height and the second end has a second height.
12. The image display method according to claim 11 , wherein the first height is greater than the second height.
13. The image display method according to claim 12 , wherein the moving object only moves from the first end point to the second end point.
14. An image display method comprising:
overlaying and displaying grid lines having a plurality of line segments on an object surface; and
displaying a first moving object on a first line segment of the grid lines and concurrently displaying a second moving object on a second line segment of the grid lines,
wherein a slope angle of the first line segment is different that a slope angle of the second line segment,
wherein a speed of movement of the first moving object is different than a speed of movement of the second moving object, and
wherein a speed of movement is calculated each of the plurality of line segments.
