Data processing method, apparatus, device, and medium

A data processing apparatus, comprising:

• a processor;
• and
• memory operatively coupled to the processor, the memory storing computer readable instructions that, when executed by the processor, causes the apparatus to provide:
• a path obtaining module configured to:
• obtain a set of edges, marked as usable for cutting, from a two-dimensional mesh model, the two-dimensional mesh model being a connected two-dimensional mesh in at least one two-dimensional mesh obtained by performing two-dimensional unwrapping on a virtual three-dimensional model;
• and
• search the set of edges to obtain a cut path set, the cut path set comprising at least two candidate cut paths, each candidate cut path comprising at least one edge of the set of edges, and the at least one edge cutting the two-dimensional mesh model into at least two separated two-dimensional mesh models;
• a path selection module configured to:
• calculate, for each candidate cut path in the cut path set, a path length of the candidate cut path;
• and
• calculate a structural evaluation value corresponding to the candidate cut path, the structural evaluation value representing regularity degrees of shapes of at least two sub-models obtained by cutting the two-dimensional mesh model by using the candidate cut path;
• calculate a cut evaluation estimate of each candidate cut path based on the path length and the structural evaluation value;
• and
• select one candidate cut path from the at least two candidate cut paths as a target cut path according to the cut evaluation value;
• and
• a model cutting module configured to cut the two-dimensional mesh model into at least two sub-models by using the target cut path, the at least two sub-models being used for generating a texture unwrapping result of the two-dimensional mesh model.

A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium storing a computer program, and the computer program being loaded and executed by a processor, so that a computer device having the processor is caused to:

• obtain a set of edges, marked as usable for cutting, from a two-dimensional mesh model, the two-dimensional mesh model being a connected two-dimensional mesh in at least one two-dimensional mesh obtained by performing two-dimensional unwrapping on a virtual three-dimensional model;
• search the set of edges to obtain a cut path set, the cut path set comprising at least two candidate cut paths, each of the at least two candidate cut paths comprising at least one edge of the set of edges, and the at least one edge cutting the two-dimensional mesh model into at least two separated two-dimensional mesh models;
• for each candidate cut path in the cut path set:
• calculate a path length of the candidate cut path,
• calculate a structural evaluation value corresponding to the candidate cut path, the structural evaluation value representing regularity degrees of shapes of at least two sub-models obtained by cutting the two-dimensional mesh model by using the candidate cut path, and
• calculate a cut evaluation estimate of the candidate cut path based on the path length and the structural evaluation value;
• select one candidate cut path from the at least two candidate cut paths as a target cut path based on the cut evaluation values of the at least two candidate cut paths;
• and
• cut the two-dimensional mesh model into at least two sub-models by using the target cut path, the at least two sub-models being used for generating a texture unwrapping result of the two-dimensional mesh model.
