Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, based on the examples herein, which are within the scope of the protection sought by those of ordinary skill in the art without undue effort, are intended to be encompassed by the present application.
Referring to fig. 1, a flowchart of a method for brushing areas of a three-dimensional building material is provided in an embodiment of the present application. The embodiment of the application provides a method for brushing and pasting a region of a three-dimensional building material, and as shown in the figure, the method for brushing and pasting the region of the three-dimensional building material specifically comprises the following operation steps:
and 11, acquiring input point information, a generation mode and geometric data of a target building.
The generation method may include, but is not limited to: horizontal, vertical, horizontal surround, vertical surround, and custom objects.
And 12, generating a brushing area according to the input point information, the generation mode and the geometric data, and creating an area layering entity by using the brushing area.
And step 13, acquiring a material object, and setting the material object to the regional layering entity.
In this embodiment, a brushing area is generated by the acquired input point information, the generation mode and the geometric data of the target building, and an area layering entity is created by using the generated brushing area, so that each created area layering entity can be presented on the surface layer of the three-dimensional building and is independent of each other and is associated with the three-dimensional building; the method has the advantages that the obtained material objects are used for realizing the material brushing of the regional layered entity, so that the surfaces of various materials required for brushing of a target building are not required to be distinguished by cutting wiring and the like, the brushing areas are generated and converted into regional layered entities, the regions to be brushed on the surface of the target building can be divided, the mutual independence of the regional layered entities presented between the brushing areas can ensure that the brushing of the materials can be accurate to the appointed range, the brushing speed and flexibility are effectively improved, meanwhile, the target building model is not influenced, and the repeated editing pressure of the three-dimensional building entity is reduced.
In the implementation, the input point information is used for determining a to-be-brushed area on a target building, for example, in a three-dimensional modeling interface, the target building is a building model of a six-story building, and the to-be-brushed area is a second-story building, and then the input point information is click point information randomly selected by an operator on each of the top-story and bottom-story edges of the second-story building of the building model.
Because the acquired generating manners are different, the step of generating the brushing area may also be different, and in some embodiments, the generating the brushing area according to the input point information, the generating manner and the geometric data, and creating the area layering entity by using the brushing area may specifically include: whether the creation of the layering entity of the current area needs to be mapped or not can be judged according to the acquired generation mode, if the judgment result is that the creation is not needed, for example, when the generation mode is horizontal, vertical, horizontal surrounding or vertical surrounding, mapping is not needed, a brushing area can be generated according to the input point information, the generation mode and the geometric data of the target building, the obtained brushing area and the target building are associated, and the brushing area is converted into the layering entity of the area.
In the implementation, after the fact that mapping is not needed in the creation of the layering entity of the current area is determined, a normal direction can be determined through a generation mode and geometric data of the target building, a clicking point can be determined according to the acquired input point information, an infinite area can be constructed through the clicking point and the normal direction, virtual cutting and limiting are carried out on the target building through the infinite area, a brushing area corresponding to an area to be brushed on the target building can be created, the obtained brushing area is associated with the target building, the brushing area is converted into the layering entity of the area, the data of the obtained brushing area can be displayed on the surface of the target building in the form of the layering entity of the area, and the data of the brushing area can be changed correspondingly along with the change of the target building. For example, the target building is a six-story building, the area to be brushed is a third story building, then the acquired generation mode can be transverse encircling, on the three-dimensional operation interface, an operator can click on the top-story edge and the bottom-story edge of the third story building of the target building by using a mouse arrow to determine that the area to be brushed is the third story building, then the input point information is two click points, the normal direction of the area to be generated can be obtained through the acquired geometric data and the generation mode of the target building, two infinite surface areas can be determined according to the determined input point information and the normal direction of the area to be generated, one infinite surface area is positioned at the junction of the second story building and the third story building (the bottom-story building), the other infinite surface area is positioned at the junction of the third story building and the fourth story building (the top-story building), the target building can be virtually cut into three parts, and the middle part is the third story building, and the entity area can be brushed through the transverse encircling, and the obtained brushing area is converted into the entity area to be layered and displayed on the target building surface area.
Correspondingly, after determining whether the creation of the current brushing area needs to be mapped according to the generation mode, the area brushing method of the three-dimensional building material may further include: if the judgment result is needed, an input brushing image can be obtained, the brushing image is projected onto a target building in a mapping mode, a mapping result is obtained, and a brushing area is obtained through the mapping result; and associating the brushing area with the target building, and converting the brushing area into an area layering entity.
When the method is implemented, the mapping method is used for projecting the brushing image to the target building to obtain a mapping result, and the brushing area is obtained through the mapping result, which specifically comprises the following steps: stretching the brushed image to obtain an intermediate; based on the input point information, performing intersection operation on the intermediate and the area of the target building to obtain a brushing area; and associating the brushing area with the target building, and converting the brushing area into an area layering entity.
The target image to be brushed is required to be brushed on a target building. In implementation, the brushing image may be a pre-created image, an image that is currently drawn by an operator, or an image obtained by other means.
In the specific implementation, in a three-dimensional operation interface, after determining that the creation of a current brushing area needs to be mapped, acquiring an input brushing image, and stretching the brushing image by taking the current three-dimensional operation interface as a reference and taking the direction perpendicular to the three-dimensional operation interface as a stretching direction to obtain an intermediate; based on the input point information determined by an operator on the target building, performing a bootstrapping operation on the intermediate and the area of the target building to obtain an intersection result, constructing a brushing area by using the intersection result, binding the constructed brushing area with the area to be brushed of the target building, constructing an area layering entity by using the data of the brushing area, and displaying the brushing area on the surface of the target building through the area layering entity.
In some embodiments, to facilitate modifying the region scope of the region layered entity, the region brushing method of the three-dimensional building material may further include: acquiring area data of an area layering entity; determining the midpoint of each side of the regional layered entity through the area data; taking the middle point of each side as a freely edited pinch point, so that a user can edit the range of the regional layered entity according to the pinch point; and acquiring editing data input by a user, and updating the position of the current pinch point according to the editing data.
In practical application, in the three-dimensional operation interface, an operator can edit the size of the regional layered entity by using the pinch points, for example, the regional layered entity displayed on the target building is a rectangle, the midpoints of four sides of the rectangle are all pinch points of the regional layered entity, and the operator can change the size of the regional layered entity by dragging the pinch points through a mouse.
In some embodiments, there may be multiple areas to be brushed on the target building, and the corresponding area layering entities may also be multiple, so as to ensure the independence and association of overlapping areas between the area layering entities, after creating the area layering entities by using the generated brushing area, the area brushing method of the three-dimensional building material may further include: and acquiring the hierarchy requirements, and determining the hierarchy attribute of the regional hierarchy entity according to the hierarchy requirements.
In particular, there may be multiple regional layered entities on a target building, where each regional layered entity corresponds to a hierarchical attribute, for example, two regional layered entities have overlapping regions, and then a regional layered entity with a high hierarchical attribute is located above a regional layered entity with a low hierarchical attribute; in a default situation, the hierarchy attribute of the newly created regional hierarchy entity can be set to be the highest level, the hierarchy is progressive layer by layer, and each newly created regional hierarchy entity is placed on the top layer of the last created regional hierarchy entity. And moreover, an operator can set the hierarchy requirement according to the actual requirement, so that the hierarchy attribute of the regional layering entity can be determined according to the hierarchy requirement, and the condition that the regional brushing and pasting result of the three-dimensional building material meets the actual requirement is ensured.
