Texture mapping method, recording medium, program, and program executing apparatus
View Patent ↗A method of simply mapping a texture such as a light point texture onto a three-dimensional model comprises the steps of designating a three-dimensional model having polygons to be subjected to a texture mapping process, designating a texture used for the texture mapping process, and transforming the polygons by perspective transformation and performing the texture mapping process by mapping the designated texture onto respective vertices of the transformed polygons.
1. A method of mapping a texture for displaying a three-dimensional image on a monitor, said method being carried out by executing a program by an image processing apparatus having CPU, said method compromising the steps of:
selecting a designated three-dimensional model from a plurality of three-dimensional models each formed by polygons by activating a pointing device when a cursor is positioned on the designated three-dimensional model; and
mapping at a time a plurality of textures having identical shapes on respective vertices of said polygons of said selected three-dimensional model.
2. A method according to claim 1 , wherein said mapping step comprises the step of selecting said plurality of textures.
3. A method according to claim 1 , wherein said plurality of textures are light point textures, and said three-dimensional image displayed on said monitor includes light point textures mapped on respective vertices of said polygons of said designated three-dimensional model.
4. A method according to claim 1 , further comprising the step of designating a color of said plurality of textures.
5. A method according to claim 1 , further comprising the step of transforming said polygons by perspective mapping.
6. A recording medium storing said program for carrying out the method according to claim 1 .
7. A recording medium according to claim 6 , wherein said recording medium further stores data of said designated three-dimensional model and data of said designated texture.
8. An image processing apparatus having a CPU for executing a program to display a three-dimensional image on a monitor, said image processing apparatus comprising:
means for selecting a designated three-dimensional model from a plurality of three-dimensional models each formed by polygons in response to activation of a pointing device when a cursor is positioned on the designated three-dimensional model; and
means for mapping at a time a plurality of textures having identical shapes on respective vertices of said polygons of said selected three dimensional model.
9. An image processing apparatus according to claim 8 , wherein said mapping means selects said plurality of textures.
10. An image processing apparatus according to claim 8 , wherein said plurality of textures are light point textures, and said three-dimensional image displayed on said monitor includes light point textures mapped on respective vertices of said polygons of said designated three-dimensional model.
11. An image processing apparatus according to claim 8 , further comprising the step of designating a color of said plurality of textures.
12. An image processing apparatus according to claim 8 , further comprising the step of transforming said polygons by perspective mapping.
