Detailed Description
The method, the device, the computer equipment and the storage medium for displaying the three-dimensional model provided by the invention are explained and illustrated in detail below with reference to the attached drawings.
As shown in FIG. 1, one or more embodiments of the present invention can provide a method of three-dimensional model display, which can include, but is not limited to, at least one of the following steps.
Step 100, creating a mapping relation between the construction segment graphic elements and the associated graphic elements. The three-dimensional model comprises a plurality of construction section graphic elements, wherein the construction section graphic elements comprise at least one association graphic element.
Optionally, creating the mapping relationship between the construction segment primitives and the associated primitives according to the embodiment of the present invention includes: screening graphic element record information associated with the graphic element of the construction section from a database to create a first mapping relation between the graphic element of the construction section and the associated graphic element; the first mapping relationship is used for representing the inclusion relationship between the construction section graphic elements and the associated graphic elements, namely, the current construction section contains the graphic elements; the database of the embodiment of the invention can be a steel bar database, and the first mapping relation can be a mapping list (< construction section primitives, association primitive list >); the embodiment of the invention can screen out construction section graphic element record information corresponding to the association graphic element in the first mapping relation from the database to create a second mapping relation between the association graphic element and the construction section graphic element, wherein the second mapping relation can be a mapping list (< association graphic element, construction section graphic element list >); the second mapping relationship is used for representing the membership relationship between the associated primitive and the primitive of the construction section, namely whether a primitive belongs to the current construction section.
For example, prefabricated walls related to specific engineering belong to father and son primitives, tiger windows belong to main bodies and partial primitives, and beams belong to front and rear stage primitives. For the parent-child element, the steel bar database calculates all records as the parent element when the engineering quantity is stored; similarly, all records of the subject and part of the primitives are counted in the subject primitive, and all records of the preceding and following stage primitives are counted in the first stage primitive. The invention can accurately determine the engineering quantity record of each associated graphic element based on the mapping relation between the graphic element of the construction section and the associated graphic element. For example, for a single reinforcement member, the cast-in-situ slab stress rib has the reinforcement amount, the embodiment can obtain an associated slab primitive list from one attribute in the cast-in-situ slab stress rib, the slab stress rib maps which construction sections, and the slab primitives also need to be mapped to the construction sections; for example, the cast-in-situ plate negative bar has the steel bar quantity, one attribute in the cast-in-situ plate negative bar is required to obtain a dependent plate graphic element, the plate graphic element on which the plate negative bar depends is also required to map the construction section corresponding to the plate negative bar. The invention can accurately distinguish the graphic elements associated with each construction section from the construction section angle.
Step 200, receiving selection information of the construction section, and determining the current selected construction section graphic element according to the selection information. When the method is used by a user, the three-dimensional model displayed can be selected by using a mouse or screen touch and the like or selected in a construction section list, and other construction section selection modes can be adopted, so that the selection information of the construction section can be automatically generated on the basis of selection operation, and the currently selected construction section is determined to be the construction section to be specially checked. It should be understood that the selected construction site may be one or more in the practice of the present invention, i.e., the currently selected construction site primitives may be one or more. Wherein, when the current selected construction section graphic element is a plurality of, a selected construction section graphic element set can be formed.
And 300, traversing the associated primitives contained in the three-dimensional model, and judging whether the traversed associated primitives belong to the currently selected construction stage primitives according to the mapping relation. The embodiment of the invention can specifically judge whether the traversed associated graphic element belongs to the graphic element of the currently selected construction section according to the second mapping relation, namely judging whether the graphic element belongs to any graphic element of the three-dimensional model until all graphic elements in the three-dimensional model are traversed, so as to determine all associated graphic elements contained in the graphic element of the currently selected construction section.
Step 400, displaying the associated graphic elements belonging to the graphic elements of the currently selected construction section. The method and the device display the primitives in the construction section to be displayed based on the technical scheme, so that the requirement of a user for checking part of the model of the construction section is met, and the method and the device are convenient to compare with the on-site construction section better.
As shown in fig. 2, the embodiment of the present invention further includes a process of cutting the primitive. Specifically, displaying the associated primitives belonging to the currently selected construction segment primitive includes: judging the primitive types of the associated primitives belonging to the currently selected construction section primitives, and determining the cutting mode of the associated primitives according to the primitive types so as to cut the associated primitives; and displaying the related graphic elements which are cut and belong to the graphic element range of the construction section. Based on the improved technical scheme, the invention can adopt different cutting modes for the graphic primitive according to the graphic primitive types belonging to the construction section so as to effectively display the associated graphic primitive belonging to the currently selected construction section graphic primitive.
Specifically, the method for determining the cutting mode of the associated primitive according to the primitive type comprises the following steps: according to the method, the intersection point of the line primitive and the construction section primitive is determined as a cutting point, the equivalent cutting is carried out at the intersection point of the line primitive and the construction section primitive in a point cutting mode, when the method is implemented, the intersection points of the line primitive midline and the construction sections are determined, then rectangles are constructed in each construction section according to the distance between the midline and the line primitive left side line and the distance between the line primitive right side line and the midline, and the range in the rectangles is used as the range to be displayed by the line primitive. According to the method, the device and the system, the type of the graphic element is a face graphic element, the intersecting line of the face graphic element and the graphic element at the construction section is determined to be used as a cutting line, and the line cutting mode is adopted to cut at the intersecting line of the polygon where the face graphic element is located and the polygon where the graphic element at the construction section is located. For dot primitives, the embodiment of the invention does not cut, and a complete model of the dot primitive is also displayed at the construction site boundary. Based on the improved graphic element cutting technical scheme, the graphic element cutting method and the graphic element cutting device can effectively display the point graphic element, the line graphic element and the surface graphic element and meet the viewing requirement of the graphic element in the construction section of a user.
Alternatively, the present invention is also capable of creating a construction site shutdown button. Specifically, the method for displaying a three-dimensional model provided by the embodiment of the invention can further include: generating and displaying a closing button corresponding to the current selected construction section graphic element, and receiving click information of the closing button; and changing the associated graphic elements belonging to the currently selected construction section graphic element from display to hiding according to the click information. The closing button in the embodiment of the invention is arranged at the upper right corner of the displayed construction section model so as to be convenient for a user to check and click. The generating the close button corresponding to the currently selected construction section graphic element in the embodiment specifically comprises: traversing the current construction section graphic element, finding out the vertex closest to the maximum point of the bounding box of the construction section graphic element in all vertexes of the current construction section, generating a displayable closing button at the vertex, and storing the mapping relation between the closing button and the current construction section graphic element, so that the corresponding construction section graphic element can be found when clicking a closing button again after a plurality of construction sections are selected to enter the three-dimensional model of the construction section. After a user clicks a closing button, removing the current construction section graphic element from the current selected construction section graphic element set according to the mapping relation between the closing button and the current construction section graphic element so as to remove the construction section graphic element corresponding to the closing button; the primitives are then re-traversed, and at least one of the construction segment primitives corresponding to the clicked shutdown button changes from displayed to hidden since the construction segment primitive corresponding to the clicked shutdown button no longer belongs to the selected construction segment primitive set. Based on the improved technical scheme, the hidden operation can be carried out on the current construction section graphic elements which are independently displayed in a mode of clicking the closing button, particularly when a plurality of construction section graphic elements are simultaneously displayed, the hidden operation meets the requirement that a user closes at least one construction section graphic element, and can also meet the requirement that the user displays the closed construction section graphic elements again.
The present invention also enables the display of the rebar as shown in fig. 3. The method for displaying the three-dimensional model provided by one or more embodiments of the present invention may further include: determining the reinforcement line of the associated primitive of the currently selected construction section primitive according to the mapping relation between the construction section primitive and the associated primitive; and the reinforcement lines are displayed or hidden according to the position relation between the associated graphic elements and the graphic elements of the construction section. According to the embodiment of the invention, the associated graphic elements contained in the graphic elements of the currently selected construction section can be determined according to the first mapping relation, and the reinforcement line is created and displayed.
As shown in fig. 4, in the embodiment of the present invention, displaying or hiding a reinforcement wire according to a positional relationship between an associated primitive and a construction section primitive includes: hiding the reinforcement wire of the associated graphic element according to the fact that the associated graphic element is completely inside the graphic element in the construction section; and displaying the reinforcement wire of the associated graphic element according to the part of the associated graphic element in the graphic element of the construction section. Based on the reinforcement wire display and hidden processing mode, the reinforcement wire display method and the reinforcement wire display device can display reinforcement wires in a targeted manner according to actual requirements, avoid the problems of screen refreshing influence frame rate, screen flickering and the like possibly caused by simultaneously displaying the reinforcement wires of all the primitives under a construction section, and improve the use experience of users. In addition, the invention can display whether the reinforcing steel bars are accurately disconnected at the boundary of the construction section on the construction section model according to the method, and accurately generate the throwing bars according to the arrangement on the basis, and the method is not limited to the method.
As shown in fig. 3 and 4, before the reinforcing steel bar line is created, judging whether the graphic element is completely inside the construction section according to the geometric relationship between the graphic element and the construction section, and if the polygon of the graphic element under the world coordinate system is inside the polygon of the construction section, judging that the graphic element is completely inside the construction section; otherwise, judging that the graphic primitive is not completely inside the construction section. If the graphic element is completely inside the construction section, creating a graphic element corresponding reinforcement line, but setting the created reinforcement line to be hidden, and displaying the part of the reinforcement line hidden by default when the user switches the display mode from the entity display mode to the wire frame display mode. In an entity display mode, the embodiment of the invention can display the corresponding steel bar lines of the incomplete inside of the construction section of the graphic element, the steel bar lines visible by the current component and the steel bar lines of the incomplete inside of the construction section; for example, for a particular primitive of larger size (e.g., a face primitive), embodiments of the present invention can determine which rebar of such primitives is completely inside the construction site and which rebar intersects the construction site when calculating the amount of rebar, and in the solid display mode, rebar that is completely inside the construction site will not be displayed. Based on the response to the user operation, the embodiment of the invention displays or hides the reinforcement wire according to the position relation between the associated graphic element and the graphic element of the construction section, and the method further comprises the following steps: refreshing the display state of the reinforcement wire under the condition of closing one construction section or switching the display mode or modifying the display setting, and of course, the embodiment of the invention can also refresh the display state of the model under the condition of closing one construction section or switching the display mode or modifying the display setting. For example, the embodiment of the invention can realize the switching of four states of an entity display mode, a wire frame display mode, an edge display mode and a transparent display mode through a display state switching tool; for example, after the wire frame display mode is switched, the three-dimensional display of all components can be realized in the construction section, and the arrangement of the steel bars in the construction section is more visual. In addition, on the basis of the method, the device and the system, the steel bar information can be checked and edited, when a user clicks the steel bar line, namely when the steel bar line selection information is received, the steel bar is set to be in a selected state, and the steel bar can be stored in a steel bar selection set object; in this embodiment, each steel bar stores length information, character string information such as a steel bar length formula, position information of a steel bar line, and the like; the text display node is created according to the character string information, the color can be set to be a preset color, for example, green, then the position of the text display node is set, and the functions of editing the steel bar, checking the detailed engineering quantity of the steel bar and the like can be synchronously matched, but the method is not limited to the method.
