The technical scheme for solving the technical problems is as follows:
the invention discloses a flow chart of a method for three-dimensional materialization of an entity in scene conversion.
The invention provides a method for three-dimensional materialization of an entity in scene conversion, which comprises the following steps:
step one, establishing a general attribute structure of entity visualization;
classifying all entities, and analyzing influence factors and constraint relations of the entities of different classes;
step three, establishing a visual attribute structure of an adaptive subclass through entity classification and analysis;
selecting a proper appearance structure generation mode aiming at the entities of different types;
fifthly, extracting and reasoning influence factor information required by the visual attribute structure from the text;
and step six, generating a visual three-dimensional entity through the influence factor information and the appearance structure of the entity.
The method for three-dimensional materialization in the context conversion comprises the following steps:
step 1.1: solid structure
Traditionally, definitions of entities can be represented by triples, such as: entity names (concepts, attributes, attribute values), taking into account the special case of an entity in a scene, the triple form of an entity concept can be extended to a quintuple, such as: entity name (conceptual domain, attribute value, state form, dependency element).
The quintuple expression of the entity structure is as follows: e (c, a, v, s, d)
c represents the basic concept domain of the entity, and is the description of the basic category and the special constraint condition of the entity;
a represents the visualization attribute of the entity, and in the present document, the visualization attribute of the entity is a function aggregate which determines the appearance of the entity and comprises an entity appearance structure function and a surface texture function;
v represents an attribute value relative to the visual attribute, is an independent variable of a visual attribute function, and is a general term of a parameter causing the change of the appearance attribute of the entity;
s represents the behavior state of an entity in a scene, and only comprises two states: static and dynamic;
d represents another entity on which the entity depends in the scene, and is a relationship node of the scene information network.
Step 1.2: visual attribute structure
The expression form of the entity visualization attribute structure is as follows:
E(S'(x1,x2,…,xn),T'(y1,y2,…,yn),R'(z1,z2,…,zn))
s' represents the outline structure mapping rule of the entity; x is the number ofiE S (i is 1,2, …, n) represents a parameter influencing the physical appearance structure;

t is a finite set of texture variables, and
a is a finite set of appearance variables, and
the method for three-dimensional materialization in the context conversion comprises the following steps:
the purpose of entity classification is to determine the concept domain of an entity, thereby narrowing the retrieval range of information required in the entity generation process and more effectively improving the entity generation efficiency. The invention classifies the entities based on the cognitive characteristics of human beings and the attribute characteristics generated by visualization, and divides the visualized entities into: plants, animals, humans, artifacts and natural objects, and subclassing according to the following rules:
first, there is a detailed reference for the subclassification of plants and animals in ecology. Meanwhile, plants and animals are natural entities with a growth rule capable of being followed, and the appearance structure and the surface texture are influenced by limited constraint factors, so that the generation of the entities is controlled conveniently.
Second, human being as a high-grade animal, the growth rule of its shape structure can naturally follow, but its living environment is complex, so that the surface texture is influenced by the cross of various factors, resulting in more complex generation of entities than plants and animals.
The artificial products are indispensable entities in human living environment, are different in types due to different functions and purposes, but have the general characteristics that the general appearance of functional entities is fixed, the appearance structure and the surface texture of the functional entities are polymorphic, and the functional entities present artistic characteristics.
And fourthly, the natural entity exists objectively, the external structure of the natural entity is not changed due to external change, most surface textures are unchanged, and only the surface textures of a few entities are influenced by natural factors.
The method for three-dimensional materialization in the context conversion comprises the following four steps:
in order to adapt to the rationality of the three-dimensional entity appearance structure, the generation mode of the entity appearance structure is divided into a combined mode and an integrated mode. The combination type is that an entity is regarded as a combination of a limited unit structure, when a child class inherits a parent class entity, the unit entities are reasonably changed and combined into a new child class entity. The generation method is as follows:
where, Σ represents combining the unit entities,
representing the attachment of the unit texture to the unit structure for the three-dimensional texture data corresponding to the virtual unit entity.
The integration is to regard the appearance structure of the entity as a whole, and only the whole appearance structure and the whole texture of the entity are needed when the three-dimensional entity is generated. The generation method is as follows:
wherein the content of the first and second substances,
is three-dimensional texture data of the entity, s (x, y) represents the overall appearance structure of the entity, represents the fit of the surface texture to the overall appearance structure
A system for three-dimensional materialization of an entity in scene transformation, comprising:
the text processing module is used for retrieving entities appearing in the text and influence factors describing the entities;
the entity classification module selects entity categories according to the entities searched by the text, so that the entity concept domain can be conveniently determined, the search range of information required in the entity generation process is reduced, and the entity generation efficiency is more effectively improved;
the visual decision analysis module generates a visual attribute structure of the category entity according to the entity classification information and judges a generation mode of an entity appearance structure aiming at the category entity;
the appearance structure generating module selects a required model from the model library according to the generating mode of the appearance structure of a certain entity and generates the appearance structure of the whole entity;
the surface texture generating module is used for generating surface texture required by the entity according to the entity influence factor and the reasoning information retrieved by the text;
and the entity generation module generates a three-dimensional entity through a mapping algorithm and a rendering mode according to the existing entity appearance structure and surface texture.
For example, the three-dimensional embodiment of the entity referred to as a "tree" in the text is as follows:
s1: establishing a general visual attribute structure of an entity;
according to the basic definition of the visualization attribute structure, the expression form of the entity visualization attribute structure is as follows:
E(S'(x1,x2,…,xn),T'(y1,y2,…,yn),R'(z1,z2,…,zn))
s' represents the outline structure mapping rule of the entity; x is the number ofiE S (i is 1,2, …, n) represents a parameter influencing the physical appearance structure;
t' represents the mapping rule of the surface texture and the illumination modification of the entity; y isiE T (i ═ 1,2, …, n) represents a parameter that affects the texture of a solid surface;
r' represents a mapping rule for reshaping the appearance of the entity after the mapping rule for the shape structure and the texture feature is completed, ziE.a (i ═ 1,2, …, n) represents parameters that constrain appearance in addition to appearance and texture.
Wherein, V is a finite variable set, which affects the appearance structure, surface texture and visual appearance of the entity visualization and is called as an entity attribute variable set; s is a finite structure variable set, and
t is a finite set of texture variables, and
a is a finite set of appearance variables, and
s2: classifying the visualized entities, and analyzing influence factors and constraint relations influencing entity visualization;
in ecology, the appearance, life habit, growing environment, type of annual growth, regional distribution and the like of plants and animals are described and studied in detail. The plants in different classes have obviously different shapes, and the shapes of the plants in the same class and different types also have detail differences. The shape structure of the annual plants does not change basically with age, the shape structure of non-annual plants may grow with age, and the shape structure of most animals grows with age. However, compared with plants, the animal has flexible postures, so that the appearance structure can be expressed more variously. The texture of substantially all plants is affected by the season, and some plants are accompanied by seasonal flowering fruits, while the texture of animals is only species dependent. Tables 1 and 2 show the classification of various types of plants and animals and the factors that externally affect their shape structure and surface texture, respectively.
TABLE 1 classification of plants and corresponding influencing factors
TABLE 2 Classification of animals and corresponding influencing factors
Particularly, people are high-grade animals, the appearance structure of the animals naturally changes with age, but unlike ordinary animals, the actions of people are more flexible and diversified, so that the appearance structure of people is more polymorphic, and meanwhile, the appearance structures of different people are also obviously different. Although the autonomy of a person is relatively strong, the basic types of postures are limited, and generally, the shape structure of the person is similar, and key parameters of the shape structure are similar within a certain age range, which facilitates the generation of the shape structure. However, since the environment in which a person is exposed to is diverse, the surface texture thereof is directly affected by various factors. Such as: race, age, region, nationality, occupation, nationality, season, clothing, hairstyle, era, etc., the detailed effects are shown in table 3.
TABLE 3 factors affecting human appearance
Most of the entities in the artificial environment are non-living, and are classified into different categories due to different functions and purposes, and although the appearances of the entities in different categories are mainly changed due to the purposes and artificial design, generally, the functional entities are generally fixed in appearance, and the appearance structure of the functional entities is polymorphic. According to the standards of various industries, the specification and the model of each entity are fixed and can be checked, so that the entity generation is convenient.
TABLE 4 Classification of artifacts and corresponding impact factors
S3: establishing a subclass entity visual attribute structure;
based on the classification and the influence factor analysis, the visual attribute structure of a subclass of entities can be known, for example, the visual attribute structure of a tree is
Tree (S ' (height, size, species, age), T ' (season, species, flowering, fruiting), R ' (annual type, region, environment))
S4: selecting a generation mode of an entity appearance structure and generating an entity model;
the generation mode of the tree shape knot type obtained by judgment is a combined type and needs to be formed by combining a trunk, primary branches, secondary branches and leaves, as shown in fig. 3(a), 3(b) and 3 (c).
S5: reasoning influence factors to generate surface textures;
