Abstract
A texture filtering apparatus includes a first generating unit configured to generate first texture data having a size designated by a user or satisfying a condition designated by the user by using not less than second texture data acquired under different conditions or generated under different conditions, a second generating unit configured to generate texture data for filtering used for filtering by using the first texture data, and a filtering unit configured to perform filtering on the first texture data by using a designated filtering condition and the texture data for filtering.
Claims16
A texture filtering apparatus comprising:
- a first generating unit configured to generate first texture data having a size designated by a user or satisfying a condition designated by the user by using not less than second texture data acquired under different conditions or generated under different conditions;
- a second generating unit configured to generate texture data for filtering used for filtering by using the first texture data;
- and
- a filtering unit configured to perform filtering on the first texture data by using a designated filtering condition and the texture data for filtering.
A texture mapping apparatus comprising:
- a first generating unit configured to generate first texture data having a size designated by a user or satisfying a condition designated by the user by using not less than second texture data acquired under different conditions or generated under different conditions;
- a second generating unit configured to generate texture data for filtering used for filtering by using the first texture data;
- a calculation unit configured to calculate a filtering condition at the time of mapping on a surface of a CG (computer graphics) model on the basis of designated CG model data;
- a filtering unit configured to perform filtering on the first texture data by using the calculated filtering condition and the texture data for filtering;
- and
- a generating unit configured to generate CG data by mapping the texture data having undergone the filtering onto the CG model data.
A texture filtering method comprising:
- generating first texture data having a size designated by a user or satisfying a condition designated by the user by using not less than second texture data acquired under different conditions or generated under different conditions;
- generating texture data for filtering used for filtering by using the first texture data;
- and
- performing filtering on the first texture data by using a designated filtering condition and the texture data for filtering.
A computer readable storage medium storing instructions of a computer program which when executed by a computer results in performance of steps comprising:
- generating the texture data having a size designated by a user or satisfying a condition designated by the user by using not less than second texture data acquired under different conditions or generated under different conditions;
- generating texture data for filtering used for filtering by using the first texture data;
- and
- performing filtering on the first texture data by using a designated filtering condition and the texture data for filtering.
