Problems solved by technology
[0003] However, when the ceramic industry turns to modern design, there are the following problems: lack of intuitive and visual analysis methods for ceramic product manufacturing
The following factors are mainly considered: In the design of ceramic products, each independent feature is usually represented by the angle, distance and various geometric constraints between geometric elements such as points, curves or surfaces in space, so there are many influencing factors, and the design When modifying, the designer needs to recalculate and modify all the above geometric constraints, and the design efficiency is greatly reduced; in actual design, there are diversity in the design of ceramic products, so there will be pole continuity and boundary incompatibility conditions when designing and modeling. High-quality geometric modeling problems, which reduce the quality of modeling, directly affect the design of ceramic products

Embodiment Construction
[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0055] First of all, based on the current development technology of ceramics, there are the following problems in the design of ceramics in my country: the lack of intuitive and visual analysis methods for the manufacture of ceramic products.
[0056] Analyze the reason: In the design of ceramic products, each independent feature is usually represented by the angle, distance and various geometric constraints between geometric elements such as points, curves or surfaces in space, so there are many influencing factors. All the above geometric constraints need to be recalculated and modified, and the design efficiency is greatly reduced; in actual design, there are diversity in the design of ceramic products, so high-quality geometric shapes such as pole continuity and boundary incompatibility conditions will be generated during design modeling Difficultie...

The invention discloses a three-dimensional aided design and visualization system and method based on a ceramic product, and belongs to the technical field of ceramic design. The method comprises the steps: solving product aided design by adopting an incremental geometric constraint formula on the basis of decomposed geometric constraints, and constructing a geometric feature model; obtaining product shape features and product ornamentation features, and constructing a fusion model for fusing the product shape features and the product ornamentation features based on the fitting curved surface of the geometric feature model; and in combination with the geometric feature model and the fusion model, creating a data model to display and analyze the product in a three-dimensional visual form. According to the system and the method, the independence and interactivity of the geometric constraint system are improved, a designer can conveniently carry out targeted modification, the response time of calculation is shortened, and the design efficiency of ceramic products is effectively improved.
