The material sorting instruction is used for instructing the server to start sorting the home decoration material models in the home decoration design file, and the wall body selection strategy can be used for selecting a target wall body model from all the wall body models in the home decoration design file. In an embodiment, the wall selection policy may be to sort each wall model in the home decoration design file according to a left-to-right sequence (or from right to left), determine that the leftmost wall (or the rightmost wall) is a target wall model if an included angle between the leftmost wall model (or the rightmost wall) and a preset coordinate system is in a preset included angle region, sort the home decoration material models corresponding to the target wall model, and when the sorting of the home decoration material models corresponding to the target wall model is completed, continue to determine the target wall model from the remaining wall models according to the wall selection policy until the sorting of the home decoration material models corresponding to all the wall models in the home decoration design file is completed.

To facilitate understanding of the step S104, an embodiment of the present invention provides an implementation manner for determining a target wall model from wall models in a virtual space according to a preset wall selection policy, and may determine candidate wall models according to a relative position sequence between the wall models, and if an included angle between a horizontal line corresponding to the candidate wall model and an abscissa axis in a preset coordinate system is in a preset included angle interval, determine the candidate wall model as the target wall model. Assuming that the preset included angle interval is 30 degrees, assuming that a wall model A1, a wall model A2 and a wall model A3 exist, if the wall models are ranked from left to right, determining that the wall model sequence is A2, A3 and A1, determining that the candidate wall model is a wall model A2, and if the included angle between the wall model A2 and the abscissa axis in the preset coordinate system is 20 degrees and is smaller than the preset included angle interval, determining that the wall model A2 is the target wall model.
Further, in the embodiment of the present invention, an arrangement order of the wall models may also be determined according to the relative positions of the wall models, for example, the order of the wall models is a2, A3, and a1, and angles between the wall model a1, the wall model a2, and the wall model A3 and an abscissa axis in a preset coordinate system are all less than 30 degrees, so that the arrangement order of the wall models is [ a2, A3, a1 ].
To facilitate understanding of the step S106, an embodiment of the present invention provides a specific implementation manner of determining a projection unit corresponding to a target wall model according to projections of each home decoration material model in a virtual space corresponding to the target wall model, where the following steps 1 to 2 are included to determine whether the home decoration material model corresponds to the target wall model:
step 1, aiming at each home decoration material model in the virtual space, determining a wall body model to which the home decoration material model belongs by adopting at least one of the following modes.
The first method is as follows: and determining the wall model to which the home decoration material model belongs according to the projection position of the specified side center point of the home decoration material model. In practical application, the wall model of the home decoration material model can be determined based on the projection position according to the following steps (1) to (3):
(1) and determining the wall model where the projection of the specified side center point of the home decoration material model is positioned as the wall model to which the home decoration material model belongs. Wherein, the designated side center point can be the center point of the back of the home decoration material model. For convenience of understanding, the embodiment of the present invention provides a projection schematic diagram of a home decoration material model, as shown in fig. 2, a projection of a central point of a back of the home decoration material model is located on a wall model a2, so that it can be determined that the home decoration material model belongs to a wall model a 2.
(2) And if the projection of the center point of the appointed side of the home decoration material model is positioned at the junction of any two wall body models, determining the wall body model with the smallest included angle with the home decoration material model as the wall body model to which the home decoration material model belongs. For example, the projection of the center point of the back of the home decoration material model is located at the junction of the wall model a1 and the wall a2, an included angle a1 between the home decoration material model and the wall model a1 and an included angle a2 between the home decoration material model and the wall model a2 are calculated, and if the included angle a1 is greater than the included angle a2, the home decoration material model belongs to the wall model a 2.
(3) And if the projection of the center point of the appointed side of the home decoration material model is positioned at the junction of any two wall body models and the included angles between the home decoration material model and each wall body model are the same, determining the wall body model with the forward arrangement sequence of the wall body models as the wall body model to which the home decoration material model belongs. For example, the arrangement sequence of the wall models is determined to be [ a2, A3, a1] according to the above method, if the projection of the center point of the back of the home decoration material model is located at the intersection of the wall model a1 and the wall a2, and the included angle a1 is equal to the included angle a2, since the arrangement sequence of the wall models is [ a2, A3, a1], that is, the wall model a1 is further forward, the morals of the wall to which the home decoration material model belongs is the wall model a 2.
The second method comprises the following steps: and determining the wall model to which the home decoration material model belongs according to the distance between the home decoration material model and the wall model. In a specific embodiment, the wall model closest to the home decoration material model may be determined as the wall model to which the home decoration material model belongs. Specifically, the distance between the home decoration material model and each wall model can be calculated, if the distance from the home decoration material model to the wall model a1 is l1, the distance from the wall model a2 is l2, and the distance from the wall model A3 is l3, and if the distance l2 is the minimum, it can be determined that the home decoration material model belongs to the wall model a 2.
And 2, acquiring a target home decoration material model belonging to the target wall model. The wall model to which all the home decoration material models in the home decoration design file belong is determined by the method, and if the target wall model is the wall model A2, all the home decoration material models belonging to the wall model 2 can be directly obtained and determined as the target home decoration material model.
To facilitate understanding of the step S108, an embodiment of the present invention further provides a specific implementation manner for determining an arrangement order of the target home decoration material models based on a position of the projection corresponding to the target home decoration material model in the target wall model, which is shown in the following steps a to d:
step a, judging whether an associated home decoration material model associated with the target home decoration material model exists in the virtual space. If yes, executing step b; if not, executing step c. The target home decoration material model and the associated home decoration material model belong to the same home decoration combination. For example, in the process of designing the home decoration, a plurality of cabinets may be set as a home decoration combination, or the tea table and the sofa may be set as a home decoration combination, and each home decoration material model in the home decoration combination has an association relationship with the rest home decoration material models in the home decoration combination.
And b, determining the height value of each home decoration material model in the home decoration combination to which the target home decoration material model belongs from the ground, and determining the arrangement sequence of each home decoration material model in the home decoration combination according to the sequence of the height values from small to large. In practical application, if the target home decoration material belongs to a home decoration assembly, the home decoration material models included in the home decoration assembly can be sorted first, for example, the home decoration material models with the ground clearance of less than 700mm are sorted first, then the home decoration material models with the ground clearance of more than or equal to 700mm and less than or equal to 1000mm are sorted, finally the home decoration material models with the ground clearance of more than 1000mm are sorted, and all the home decoration material models in the home decoration assembly are sorted according to the range. And after finishing the sequencing of the home decoration combination, sequencing other home decoration combinations or target home decoration material models without related home decoration material models.
And c, determining the height value of the target household material model corresponding to the target wall body model from the ground, and determining the arrangement sequence of the target household material models according to the sequence of the height values from small to large. For example, for a target home decoration material model without a related home decoration material model, the home decoration material models with the ground clearance of less than 700mm can be sorted according to the rule of firstly sorting the home decoration material models with the ground clearance of less than 700mm, then sorting the home decoration material models with the ground clearance of more than 700mm and less than or equal to X and less than or equal to 1000mm, and finally sorting the home decoration material models with the ground clearance of more than 1000 mm.
And d, if the height values of the target home material models corresponding to the target wall models from the ground are the same, determining the arrangement sequence of the target home material models according to the sequence from near to far between the target home material models and the wall models. If the height of the target home decoration material B1 from the ground is the same as the height of the target home decoration material B2 from the ground, and if the target home decoration material B1 is closer to the target wall model, the sequence of the target home decoration materials can be obtained as [ B1, B2 ].
Based on the method for determining the order of the models in the virtual space provided by the above embodiment, the embodiment of the present invention further provides another method for determining the order of the models in the virtual space, which, in consideration of practical application, the cabinet body is used as an important link in the design of home decoration, because the number of the cabinet bodies is large and the styles are various, the quality of the layout design is directly related to the overall effect of the home decoration design, in addition, due to the fact that a plurality of associations and limitations exist among the cabinet bodies, a plurality of factors need to be considered, once deviation occurs on the sequencing numbers, the layout design of the cabinet bodies is caused to be problematic, in order to improve the problem, the embodiment of the invention takes the home decoration material model as the cabinet body model for illustration, therefore, the method for determining the sequence of the model in the virtual space provided by the embodiment of the invention can be used for better determining the sequence of the home decoration material models such as the cabinet body and the like, so that the sequence of the cabinet body is more reasonable. Referring to fig. 3, a flow diagram of another method for determining a model order in a virtual space is shown, where the method includes a determination method of a wall to which a unit belongs, a sort rule of a wall unit, and a sort rule of a combination, and the method mainly includes the following steps:
in step S302, a first wall (i.e., the target wall model) is determined from the walls in the home decoration design file.
Step S304, determining whether there is a customization unit (i.e., the aforementioned home decoration material model) in the home decoration design file. If yes, go to step S306; if not, step S314 is performed. Wherein, the home decoration material model can comprise the whole cabinet body or the whole door and the like. Taking the case that the customization unit is a cabinet, when determining the wall to which the customization unit belongs, the following rules can be followed: the wall projected by the central point of the back of the cabinet body is used as the wall surface to which the cabinet body belongs, and the wall surfaces are mapped according to the central point of the cabinet body to sort even if the angle of the cabinet body is more inclined to the other wall; when two walls are arranged in the projection direction of the cabinet body, the closest wall is taken as the standard; when the central projection of the cabinet body is the junction of the two walls, the included angle between the cabinet body and the two walls is used for judging which wall body the cabinet body belongs to.
Further, can also judge the wall body that the cabinet body belongs to according to the contained angle between the cabinet body and the wall body, it is specific: when the included angle between the cabinet body and one wall body is smaller, the cabinet body belongs to the wall body; when the included angles between the cabinet body and the two wall bodies are equal, the cabinet body belongs to the wall body with the wall body sequencing close to the front. The plane projected by the central point of the back of the wall body is the front of the wall body, and the units belonging to the same wall body exist in the CAD of the wall body on the same side when the CAD is derived.
Step S306, determining a first customization unit projected on the first wall body.
Step S308, judging whether the first customization unit belongs to the home decoration combination. If yes, go to step S310; if not, step S312 is performed.
And S310, sorting other customization units in the home decoration combination of the customization units according to a combination sorting rule according to the projection of the first customization unit on the first wall body. Wherein the combined ordering rule may include: sorting from the combined ground cabinets, then sorting the middle cabinets in the combination, and finally sorting the hanging cabinets in the combination; and after the combination and sorting are finished, continuing to sort backwards according to the wall. The cabinet sequencing priority in the combination is higher than that of other cabinets, but the whole cabinet sequencing is obeyed. In addition, the sorting function described above is effective when a plan is derived CAD, and any plan is sorted with the cabinet at the last moment when CAD is derived.
Step S312, sorting the first customization units according to their projections on the first wall. Wherein the sequence number of the first customization unit must be consecutively numbered following the sequence number of the last customization unit. During specific implementation, the cabinets can be sorted according to the height of the cabinets from the ground, when the projections of the cabinets on the same wall surface are overlapped, the cabinets close to the wall are selected to be sorted preferentially, and one of the two completely overlapped cabinets is selected to be sorted preferentially; the units with the customized unit attribute of the capping plate are sorted (by taking a wall as a unit) after the other customized units are sorted; when other customization units are sequenced (including a top sealing plate), the unit attribute is that CAD is to be output independently of the island, and the serial number of the island is sequenced after other cabinets are sequenced; the serial number of the island platforms is equal to the sequencing rule of the combined cabinet body.
Specifically, when the cabinets are sorted according to the ground clearance height of the cabinets, the customization units can be sorted firstly, the ground clearance height is less than 700mm, then the ground clearance height is not less than 700mm and not more than X and not more than 1000mm, and finally the ground clearance height is more than 1000 mm; when the projection left sides of the units on the wall surface are aligned, the units are sorted first and have small ground height, and then are sorted and have large ground height; when the left projection sides of the units on the wall surface are aligned and have consistent heights, the units are sorted firstly and are close to the wall, and then are sorted and are far away from the wall.
Step S314, determine whether there is a next numbered wall. If yes, go to step S304; if not, the process is ended. In the concrete implementation, all units projected on one wall can be sorted and then sorted to the unit of the next wall, and all floor cabinets on one wall can be sorted and then hung in the last row of the middle cabinet.
To sum up, the method for determining the material sequence in the virtual space provided by the embodiment meets the actual requirements, follows the general numbering rules, has stronger practicability, enables the cabinet body layout in the home decoration design to be more reasonable, and has an important role in the generation of the cabinet body sequencing method by the CAD auxiliary function in the home decoration design software.
