Abstract

Claims (37)

1. An information processing apparatus for designing a mold for forming a molded product, comprising:

a processor; and

memory storing program instructions that, when executed by the processor, cause the information processing apparatus to perform operations comprising:

acquiring shape data indicating a three-dimensional shape of the mold prior to a processing to be applied to a surface of the mold;

acquiring a mold release direction in separating the molded product from the mold;

acquiring a processing parameter for the processing to be applied to the surface of the mold;

generating a first processing parameter map and a second processing parameter map;

calculating, based on the shape data, the mold release direction, and the processing parameter, a difference between the first processing parameter map and the second processing parameter map, the first processing parameter map and the second processing parameter map each indicating a correspondence between a position on the surface of the mold and the processing parameter;

based on information about the difference, acquiring an adjustment parameter based on a user instruction via a user interface, the adjustment parameter indicating a balance between emphasis on fidelity of surface texture of the molded product and emphasis on continuity of the surface texture of the molded product;

generating a third processing parameter map based on the adjustment parameter; and

notifying the information about the difference.

2. The information processing apparatus according to claim 1 , wherein at least one of the first processing parameter map and the second processing parameter map is a processing parameter map related to the surface texture of the molded product.

3. The information processing apparatus according to claim 1 , wherein the first processing parameter map emphasizes fidelity of the surface texture of the molded product, and the second processing parameter map emphasizes continuity of the surface texture of the molded product.

4. The information processing apparatus according to claim 1 , wherein the notifying notifies the information, by displaying information indicating a region where the difference is not substantially zero in the shape data.

5. The information processing apparatus according to claim 1 , wherein the notifying notifies the information, by displaying information indicating color having intensity corresponding to amount of the difference in the shape data.

6. The information processing apparatus according to claim 1 , wherein the adjustment parameter is a parameter for adjusting a balance between the first processing parameter map and the second processing parameter map.

7. The information processing apparatus according to claim 1 , further comprising a display configured to display a rendering image corresponding to each of the first processing parameter map and the second processing parameter map.

8. The information processing apparatus according to claim 1 , wherein the mold is configured to form minute irregularities on a surface of the molded product.

9. The information processing apparatus according to claim 1 , wherein the acquiring the mold release direction acquires a three-dimensional vector indicating the mold release direction, as the mold release direction.

10. An information processing method for designing a mold for forming a molded product, the information processing method comprising:

acquiring shape data indicating a three-dimensional shape of the mold prior to a processing to be applied to a surface of the mold;

acquiring a mold release direction in separating the molded product from the mold;

acquiring a processing parameter for the processing to be applied to the surface of the mold;

generating a first processing parameter map and a second processing parameter map;

calculating, based on the shape data, the mold release direction, and the processing parameter, a difference between the first processing parameter map and the second processing parameter map, the first processing parameter map and the second processing parameter map each indicating a correspondence between a position on the surface of the mold and the processing parameter;

based on information about the difference, acquiring an adjustment parameter based on a user instruction via a user interface, the adjustment parameter indicating a balance between emphasis on fidelity of surface texture of the molded product and emphasis on continuity of the surface texture of the molded product;

generating a third processing parameter map based on the adjustment parameter; and

notifying the information about the difference.

11. A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform an information processing method for designing a mold for forming a molded product, the information processing method comprising:

acquiring shape data indicating a three-dimensional shape of the mold prior to a processing to be applied to a surface of the mold;

acquiring a mold release direction in separating the molded product from the mold;

acquiring a processing parameter for the processing to be applied to the surface of the mold;

generating a first processing parameter map and a second processing parameter map;

calculating, based on the shape data, the mold release direction, and the processing parameter, a difference between the first processing parameter map and the second processing parameter map, the first processing parameter map and the second processing parameter map each indicating a correspondence between a position on the surface of the mold and the processing parameter;

based on information about the difference, acquiring an adjustment parameter based on a user instruction via a user interface, the adjustment parameter indicating a balance between emphasis on fidelity of surface texture of the molded product and emphasis on continuity of the surface texture of the molded product;

generating a third processing parameter map based on the adjustment parameter; and

notifying the information about the difference.
