Fig. 2 is a flow chart of a method for generating a stacked ceiling according to another embodiment of the present disclosure; referring to fig. 2, an embodiment of the disclosure provides a method 200 for generating a stacked ceiling, including steps S201 to S202.

Step S201, responding to the region drawing operation, and displaying a three-dimensional model of a multi-stage suspended ceiling corresponding to the region drawing operation on a display interface, wherein the multi-stage suspended ceiling comprises two suspended ceiling regions which are different in distance from a reference surface and need to be connected through a stacking component;

Step S202, in response to a first selection operation of a target boundary between two ceiling areas and a second selection operation of a stacking component template, displaying a target stacking component connected with a first ceiling area in the two ceiling areas in a three-dimensional model, and displaying a second ceiling area update in the two ceiling areas in the three-dimensional model as a target ceiling area connected with the target stacking component; the target stacking component is a stacking component obtained based on a target boundary and a stacking component template, and the target suspended ceiling area is a suspended ceiling area obtained after the second suspended ceiling area is subjected to telescopic treatment.

The method for generating the stacked suspended ceiling can be used for generating the stacked suspended ceiling, for example, can be used for supporting the design capacity of the stacked suspended ceiling of a top wall tool and perfecting the suspended ceiling function.

The stacked suspended ceiling may include a stacking member and a plurality of stacking areas, that is, a multi-stage suspended ceiling and a plurality of suspended ceiling areas, and it is understood that the stacking member needs to be properly disposed between the staggered suspended ceiling areas (with the suspended ceiling as a reference plane, the staggered suspended ceiling areas refer to the suspended ceiling areas having different distances from the suspended ceiling). The design objective of the stacking members is to support some staggered ceiling designs, i.e., there is a height difference between different ceiling area designs in a multi-level ceiling by stacking members. Meanwhile, the splicing effect on decoration can be realized between suspended ceiling areas with different height differences through the stacking component, the attractive effect is achieved, and components such as a lamp strip and the like can be installed through the stacking component.

It will be appreciated that a plurality of suspended ceiling areas may be included in the multi-level suspended ceiling, and fig. 3A to 3C are schematic plan view structures of the multi-level suspended ceiling according to an embodiment of the present disclosure, and it will be appreciated that fig. 3A and 3C are each a bottom view of the multi-level suspended ceiling, that is, a projection view from a lower direction toward the ceiling, where numerals in the suspended ceiling areas indicate distances from the ceiling (reference plane) where the suspended ceiling areas are located, which may be referred to as out-of-plane parameters (under-hanging or elevation), and dotted lines indicate boundaries between the suspended ceiling areas. As in fig. 3A, the multi-level ceiling includes three areas, the upper ceiling area on the left side is 100mm (millimeters) from the ceiling, the lower ceiling area on the left side is 300mm from the ceiling, and the ceiling area on the right side is 200mm from the ceiling. As shown in fig. 3B, the multi-stage ceiling includes inner and outer ceiling areas, the off-plane parameter of the middle ceiling area is 0mm, and the off-plane parameter of the peripheral ceiling area is 200mm. As in fig. 3C, the multi-stage ceiling includes three ceiling areas, the out-of-plane parameter of the upper middle ceiling area is 100mm, the out-of-plane parameter of the upper peripheral ceiling area is 200mm, and the out-of-plane parameter of the lower ceiling area is 300mm.

It will be appreciated that fig. 3A-3C illustrate only possible forms of multi-stage ceilings, and that particular forms may be provided according to design requirements.

In step S201, the region drawing operation may be a drawing operation of a multi-stage suspended ceiling, for example, the region drawing operation may include drawing a bottom plan view as shown in fig. 3A to 3C, and setting an out-of-plane parameter of each suspended ceiling region. Or can be realized by drawing a three-dimensional stereo graph.

In step S202, the target boundary is the boundary of the target hierarchical component, and the hierarchical component template may be a hierarchical component template selected by the user in the hierarchical component template library. The parameter shape of the target stacking component to be generated can be determined by selecting the target boundary and the stacking component template, so that the target stacking component can be displayed in a three-dimensional model, and one of the two suspended ceiling areas can be automatically subjected to expansion processing such as expansion processing or contraction processing so as to be connected with the target stacking component, and the accurate generation of the stacking component and the splicing between the stacking component and suspended ceiling areas with different heights are realized.

The stacked ceiling, i.e., the structure comprising the ceiling areas and the target stacked components between the ceiling areas, may be displayed in a three-dimensional model by step S202.

Fig. 4A to fig. 4D are schematic operation diagrams of a stacked ceiling generating method according to an embodiment of the disclosure; in one embodiment, referring to FIG. 4A, the left area of the display interface may be a drawing area 401, the right side may have a 3D view area 402 of the three-dimensional model, and the area editing operation may be entered by clicking on "area editing" (area drawing operation, editing of a planar view 404, i.e., a rectangular box, in the drawing area 401 may be performed, and parameters of a ceiling area, such as out-of-plane parameters, splitting directions, etc., may be set in a parameter setting area 403. Additionally, a rectangular box in the planar view 404 may also be formed by drawing, or a wall surface, such as a ceiling plane, in the home model may be selected.

Fig. 4B shows that dividing the planar view 404 in the drawing area 401 in fig. 4A into a sub-area a and a sub-area B by an area editing operation gives a planar view 410, and sets the out-of-plane parameter of the sub-area a to 0mm, and the out-of-plane parameter of the sub-area B to 300mm, i.e., the sub-area a is set to the ceiling, and the sub-area B is located 300mm below the ceiling. At this time, the three-dimensional view in the 3D view area 402 also updates and displays the three-dimensional model 405 of the multi-stage suspended ceiling accordingly, where the three-dimensional model 405 includes a suspended ceiling area a and a suspended ceiling area B that need to be connected by the stacking component, where the suspended ceiling area a corresponds to the sub-area a in the planar view, and the suspended ceiling area B corresponds to the sub-area B in the planar view.

It will be appreciated that the three-dimensional model of the multi-level ceiling in the 3D view area 402 is a three-dimensional model generated according to the planar view 404 and the out-of-plane parameters, etc., and the angle, the size, etc. of the three-dimensional model of the multi-level ceiling in the 3D view area 402 may be changed by rotation scaling, etc. Meanwhile, the size of the 3D view area 402 may also be scaled, i.e., changed in area in the entire display interface, by a drag operation or the like.

With continued reference to fig. 4B, after the multi-stage suspended ceiling is generated and displayed, the target boundary may be selected through a "select area" control, where in this embodiment, the boundary 406 between the sub-area a and the sub-area B in the drawing area 401 may be selected, or a boundary between the suspended ceiling area a and the suspended ceiling area B in the three-dimensional model 405 may be selected (this boundary may be a boundary of the suspended ceiling area a near the suspended ceiling area B, or may be a boundary of the suspended ceiling area B near the suspended ceiling area a).

Next, the "stacking design" control in fig. 4B may be clicked, the interface shown in fig. 4C may be displayed, the stacking component setting area 407 may be displayed in fig. 4C, by clicking the "style" control in the stacking component setting area 407, the stacking component library 408 may be displayed on the left side of the area 407, and the stacking component library 408 may be displayed with a preconfigured stacking component template, such as names and thumbnails of the stacking components 1 to 4. By selecting one of the stacking member templates, for example, stacking member 1 as the stacking member template, the interface of fig. 4D may be displayed, i.e., in the three-dimensional model 405, the ceiling area B (first ceiling area) on which the target stacking member 409 (generated according to the selected stacking member template and the target boundary) is generated, while the ceiling area a (second ceiling area) in fig. 4C is deformed into the ceiling area a '(target ceiling area) so that the ceiling area a' is connected with the target stacking member, thereby realizing the overlapping of the two ceiling areas by the stacking member.

In fig. 4D, the sub-area a may be changed to sub-area a', i.e., the boundary extends to the position of the broken line.

It will be appreciated that if the ceiling area a is not subjected to the telescoping process (i.e., the structure of fig. 4C is adopted) during the process of fig. 4D from fig. 4C, a gap will occur between the ceiling area a and the target stacking member 409, which affects the aesthetics and safety. According to the embodiment, the target stacking component can be automatically generated between the two suspended ceiling areas, and one suspended ceiling area can be subjected to expansion treatment (for example, the suspended ceiling area is expanded or contracted inwards), so that the two suspended ceiling areas can be connected with the target stacking component, and the effect of overlapping the suspended ceiling areas on different heights with the outline of the target stacking component is achieved through extension or contraction.

It can be understood that in this embodiment, only the generation process of the target hierarchical structure is illustrated, and the area arrangement, the area and the setting of each control of the display interface may be adjusted according to the actual situation, for example, the drawing area 401 may not be displayed, and three-dimensional modeling may be directly performed in the 3D view area. In addition, fig. 4A-4D are only illustrated with the multi-stage ceiling including ceiling area a and ceiling area B, and in other embodiments, the multi-stage ceiling may include other ceiling areas as well. In this embodiment, the reference plane is a plane where the ceiling is located, and in other embodiments, the reference plane may be a plane with other angles such as a vertical plane.

According to the embodiment of the disclosure, the three-dimensional model of the multi-stage suspended ceiling can be displayed on the display interface through the region drawing operation, after the target boundary between two suspended ceiling regions needing to be provided with the stacking component is selected, the target stacking component can be generated between the two adjacent suspended ceiling regions, and meanwhile, the second suspended ceiling region in the two adjacent suspended ceiling regions can be subjected to telescopic treatment, so that the two suspended ceiling regions can be connected through the target stacking component, the target stacking component can be generated between the two suspended ceiling regions rapidly, and the overlapping of the suspended ceiling regions is realized. The generation of folding level furred ceiling has been simplified, and easy operation uses the threshold low.

In some embodiments, in response to the region drawing operation in step S201, displaying, on the display interface, the three-dimensional model of the multi-stage suspended ceiling corresponding to the region drawing operation, including:

in response to the region drawing operation, displaying a planar view of the multi-stage suspended ceilings in a first region of the display interface and displaying a three-dimensional model of the multi-stage suspended ceilings in a second region of the display interface, wherein each suspended ceiling region in the multi-stage suspended ceilings corresponds to a sub-region in the planar view;

the first selecting operation of the target boundary between the two ceiling areas in step S202 includes: a first selection operation of a target boundary between two adjacent sub-areas corresponding to the two ceiling areas in a plan view.

With continued reference to fig. 4A-4B, the first region may be a drawing region 401, the second region may be a 3D view region 402, the region drawing operation may be implemented using the drawing region 401, for example, drawing a planar view in the drawing region 401, it may be understood that the planar view 404 may be a projection view of the multi-stage suspended ceiling in a direction perpendicular to the reference plane and directed toward the reference plane, with the reference plane being the ceiling, and the planar view may be a bottom view of the multi-stage suspended ceiling. As in fig. 4B, the plan view 410 includes sub-regions a and sub-regions B, each of which may correspond to one of the ceiling regions in the generated three-dimensional model.

The user may present the three-dimensional model of the corresponding multi-level ceiling in the three-dimensional model by drawing a planar view 410 in the drawing area 401. The texture of the planar view 410 and the three-dimensional model 405 may also be updated by adding texture or the like to the sub-regions of the planar view 410.

It can be understood that when drawing the plane view, whether the suspended ceiling area corresponding to the sub-area needs to be subjected to expansion processing is not required, and only the boundary of the two sub-areas needs to be simply represented by the dividing line, so that the operation process is simplified.

For example, in fig. 4B, the sub-area a and the sub-area B may be divided by using the dividing line 406, where the sub-area a and the sub-area B are adjacent areas, and the dividing line 406 is a target boundary between the two areas, that is, for a multi-stage ceiling, deformation of a ceiling area after the stacking member is set is not required to be considered in the area drawing operation, and two ceiling areas where the stacking member is required to be set may be drawn into two adjacent sub-areas in a plan view, that is, two sub-areas with a common boundary, so that drawing of the multi-stage ceiling is simplified.

In addition, when selecting the target boundary, the boundary between the two sub-regions may be selected directly from the plan view as the target boundary, such as selecting the target boundary 406 between the sub-region a and the sub-region b.

According to the embodiment, the multistage suspended ceiling can be rapidly drawn through the first area, three-dimensional modeling skills are not required to be mastered, the operation is simple, and the using threshold is low. And the target boundary is quickly selected, so that the operation is more visual.

In some embodiments, the region drawing operation includes a drawing operation for each sub-region in the plan view and a setting operation for an out-of-plane parameter for each sub-region, the out-of-plane parameter being a distance between the sub-region corresponding to the out-of-plane parameter and the reference plane.

The embodiment can quickly draw a plane view in the drawing area 401, and can quickly set out-of-plane parameters for each sub-area in the plane view through the parameter setting area 403, so that the multi-stage suspended ceiling is not required to be drawn by three-dimensional modeling, and the operation is quick.

In some embodiments, the method 200 further comprises: in response to a first selection operation of a target boundary between two ceiling areas and a second selection operation of the hierarchical component template, a second sub-area update in the plan view corresponding to the second ceiling area is displayed as a target sub-area corresponding to the target ceiling area.

As shown in fig. 4C and 4D, while the ceiling area a (the second ceiling area) is expanded into the ceiling area a ' (the target ceiling area), the sub-area a (the second sub-area) in the first area may be expanded into the sub-area a ' (the target sub-area), that is, the selected sub-area a ' may see that the boundary is located at the position where the dotted line is located, and the target stacking member may not be displayed in the plan view.

On the basis of the above embodiment, the step S202 of displaying the second ceiling region update of the two ceiling regions in the three-dimensional model as the target ceiling region connected to the target stacking member includes:

determining a second ceiling region from the two ceiling regions based on a first preset rule;

and performing outward expansion treatment on the second suspended ceiling area based on the setting parameters of the target stacking component to obtain a target suspended ceiling area.

The first preset rule may be a preset rule, and the second ceiling area, that is, the ceiling area needing to be subjected to the expansion processing, may be determined from the two ceiling areas based on the first preset rule.

FIG. 5 is a plan view of a multi-stage ceiling provided by an embodiment of the present disclosure; referring to fig. 5, in some embodiments, determining a second ceiling region from the two ceiling regions based on a first preset rule includes:

Determining a first direction of a target boundary in one of the two ceiling areas and a second direction of the target boundary in the other of the two ceiling areas based on a preset sequential connection direction of the boundaries in the ceiling areas;

and determining a target direction matched with the placement direction of the target stacking member from the first direction and the second direction, and determining a ceiling area corresponding to the target direction as a second ceiling area.

It will be appreciated that in the first preset rule, a preset sequential connection direction of the boundaries in the ceiling region may be set, the sequential connection direction being related to the contour shape, for example, the preset sequential connection direction of the boundaries of the outer contour is counterclockwise and the preset sequential connection direction of the boundaries of the inner contour is clockwise as is usual in the art. Since the outlines of the sub-areas a and b are the outer boundaries of the areas, the sub-areas a and b are the outer contours, and the directions of the four boundaries in the sub-area a and the directions of the four boundaries in the sub-area b are as shown in fig. 5. It can be seen that the direction of the target boundary 501 in the sub-region a (first direction) is from bottom to top, and the direction of the target boundary 501 in the sub-region b (second direction) is from top to bottom.

Fig. 6 is an enlarged view of the stacking member 1 in fig. 4C; FIG. 7 is another angular schematic view of the three-dimensional model of FIG. 4D; referring to fig. 6 and 7, the stacking member 1 may include a first portion 601, a second portion 602, and a third portion 603. The target stacking member 710 is substantially the same shape as the selected stacking member template, i.e., stacking member 1, but may vary slightly in size. It will be appreciated that the stacking member template is directional, e.g., in fig. 6, the first portion 601 on the left is higher than the third portion 603 on the right in elevation, and then after it is created the target stacking member, the first segment 701 should still be higher than the third segment 703 in elevation.

As shown in fig. 7, when the target stacking member is placed between the suspended ceiling areas, it is first required to ensure that the placed target stacking member is at a front view angle, that is, the first section 701 of the target stacking member is higher than the third section 703, whereas in fig. 7, the front view angle is in the direction indicated by the arrow, that is, when the target stacking member is viewed from the direction indicated by the arrow, the first section 701 is higher than the third section 703, that is, the placement direction of the target stacking member.

In addition, since the plan view shown in fig. 5 is a bottom view, the arrow in fig. 7 is placed at a bottom view angle in fig. 5, resulting in a bottom-up arrow. I.e. the direction of placement of the target stacking member corresponds to a bottom-up direction in fig. 5.

Then, it may be determined that the placement direction of the target stacking member is the same (i.e., matched) as the direction (the first direction, the bottom-up direction) of the target boundary 501 in the sub-area a, and at this time, the first direction is the target direction, and it may be determined that the ceiling area a corresponding to the sub-area a is the target ceiling area requiring the expansion process.

Of course, in other embodiments, the preset sequential connection direction of the outer contours may be clockwise, and when the target direction is selected, the matching may be understood as the opposite direction, and may be specifically set according to circumstances.

In this embodiment, the target area that needs to be subjected to the expansion processing may be determined from the two ceiling areas through the first preset rule.

As shown in fig. 7, the target stacking member includes three parts, a first segment 701, a second segment 702, and a third segment 703, respectively. In fig. 7, a portion of the ceiling area a' (an area surrounded by a solid line in the drawing) to the left of the broken line is the ceiling area a before the ceiling area a is not expanded. It will be appreciated that the second section 702 needs to be attached to the ceiling area B, the outer side of the third section 703 facing away from the first section 701 needs to be flush with the edge of the ceiling area B, and the ceiling area a (second ceiling area) needs to be flared and contact with the surface of the first section 701 facing the third section 703, and it will be appreciated that, since the sub-areas a and B are originally adjacent areas, the ceiling area a (second ceiling area) needs to be flared from the position where the dotted line is located to contact with the first section 701, i.e. the ceiling area a' in the figure is obtained.

After determining the target ceiling area, the desired flared dimension of the ceiling area a (second ceiling area) may be obtained based on the set parameters of the target stacking member, such as the width of the second section 702 and the thickness of the first section 701. And then, performing expansion processing on the second suspended ceiling area to obtain a target suspended ceiling area.

In this embodiment, can realize the regional confirm of second furred ceiling and expand the processing outward automatically, need not the manual work and expand outward to the second furred ceiling region, the operation is convenient and fast more.

In addition, the shape of the stacking component templates can be various, and the method is not limited to the structure shown in fig. 6, and the deformation of the suspended ceiling area can be realized by adopting the mode of expanding the stacking component templates. When it is.

It will be appreciated that the telescoping process may include, in addition to the expanding process, a telescoping process in which, for example, the ceiling area a may be secured unchanged, the target stacking member may be set to be connected to the ceiling area a, and then the ceiling area B may be telescoping into alignment with the target stacking member, in which case the target direction may be determined with the direction opposite to the placement direction of the target stacking member as the target direction.

In some embodiments, performing the expanding process on the second ceiling region based on the setting parameters of the target stacking component to obtain the target ceiling region, including:

determining the offset of each boundary in the second ceiling region based on the setting parameters of the target stacking component, wherein the target boundary is one of the boundaries in the second ceiling region;

determining an offset curve corresponding to each boundary based on the offset of each boundary and the direction of each boundary in the second ceiling area;

and connecting the offset curves corresponding to the boundaries to obtain the target suspended ceiling area.

It will be appreciated that, during the expansion process, the offset of each boundary of the second ceiling area may be determined according to the setting parameters of the target stacking component, and since the ceiling area may be regarded as a plate-like structure with uniform thickness, determining each boundary of the second ceiling area refers to the offset of four sides in the second ceiling area, that is, the offset corresponding to the four sides where the sub-area a in fig. 5 is located.

In some embodiments, determining the offset of each boundary in the second ceiling region based on the set parameters of the target stacking member includes: determining the offset of the target boundary based on the setting parameters of the target stacking component; the offset of the remaining boundaries other than the target boundary among the respective boundaries is set as a base value.

The set parameters of the target stacking feature may determine the offset of the target boundary. The remaining boundaries may be set to a base value, and the base value may be set to 0, so that an offset of each boundary of the second ceiling region may be determined.

In some embodiments, determining the offset curve corresponding to each boundary based on the offset of each boundary and the direction of each boundary in the second ceiling region includes:

for a first boundary of the boundaries, determining the first boundary as an offset curve corresponding to the first boundary when the offset of the first boundary is a basic value;

under the condition that the offset of the first boundary is not a basic value, determining the offset direction of the first boundary based on the direction of the first boundary in the second suspended ceiling area, and determining an offset curve corresponding to the first boundary based on the offset of the first boundary and the offset direction of the first boundary;

and obtaining the offset curves corresponding to the boundaries based on at least the offset curves of the first boundary.

For example, each boundary of the second ceiling region may be traversed, and each boundary is described by a first boundary, and if the offset of the first boundary is 0, the first boundary is taken as the corresponding offset curve. If the offset of the first boundary is not 0, the offset direction can be obtained by rotating the direction clockwise by 90 degrees according to the right rule according to the direction of the first boundary in the second suspended ceiling area.

FIG. 8 is a schematic diagram of the generation of an offset curve provided by an embodiment of the present disclosure; as shown in fig. 8, the left side is a top view of the ceiling area a, and the right side is a schematic view of each offset curve obtained based on the ceiling area a. The direction of the target boundary 801 in the ceiling area a is from bottom to top, and the offset direction of the target boundary 801 is from left to right. Since the offset amount of the other boundaries except for the target boundary 801 is 0, the shape position of the offset curve is the same as the boundary shape position.

The first boundary may then be shifted in the shift direction by the amount of the shift, so that a shift curve for the first boundary may be obtained.

When the first boundary is a circular arc line, if the direction of the first boundary in the second ceiling area is anticlockwise, the radius of the offset curve can be determined to be the radius of the first boundary plus the offset, if the direction of the first boundary in the second ceiling area is clockwise, the radius of the offset curve can be determined to be the radius of the first boundary minus the offset, and then the final offset curve can be determined according to the radius of the offset curve and the start angle and the end angle of the circular arc of the first boundary.

According to the offset curve determining method provided by the embodiment, the offset curve of each boundary of the second suspended ceiling area can be obtained.

In some embodiments, performing connection processing on offset curves corresponding to respective boundaries to obtain a target ceiling region, including:

determining that the first offset curve is connected with the second offset curve under the condition that the end point of the first offset curve coincides with the start point of the second offset curve;

converting the first offset curve into a first borderless curve and converting the second offset curve into a second borderless curve under the condition that the end point of the first offset curve is not coincident with the start point of the second offset curve;

in the case where the first borderless curve and the second borderless curve have an intersection, the end point of the first offset curve is extended to the intersection, and the start point of the second offset curve is extended to the intersection.

After determining the offset curves of each boundary in the second ceiling region, each offset curve may be connected to obtain each boundary of the target ceiling region, thereby obtaining the target ceiling region.

In this embodiment, the first offset curves are taken as an example for illustration, and the directions of the first offset curves are the same as the directions of the corresponding boundaries in the second ceiling region, as shown in fig. 8. The first offset curve may be taken as the current offset curve, and the start point and the end point of the first offset curve and the next offset curve of the first offset curve may be determined according to the direction of the first offset curve.

As shown in fig. 8, if the current offset curve is the offset curve 802, the next offset curve is the offset curve 803. Since the end point of the offset curve 802 does not coincide with the start point of the offset curve 803, the offset curve 802 and the offset curve 803 may be changed to be unbounded, i.e. a straight line without end points from a line segment, and if it is a circular arc, the corresponding unbounded curve may be a full circle, so that an intersection point of the two may be found, and then the end point of the offset curve 802 and the start point of the offset curve 803 may be both extended to the intersection point, so that the two are connected.

If the current offset curve is the offset curve 803 and the next offset curve is the offset curve 804, the end point of the offset curve 803 coincides with the start point of the offset curve 804, so that the two curves are connected and no processing is needed.

In some embodiments, where the first borderless curve and the second borderless curve have an intersection, extending the end of the first offset curve to the intersection and extending the start of the second offset curve to the intersection may include:

under the condition that the first borderless curve and the second borderless curve have a single intersection point, extending the end point of the first offset curve to the intersection point, and extending the start point of the second offset curve to the intersection point;

in the case where the first borderless curve and the second borderless curve have a plurality of intersections, a target intersection closest to the end point of the first offset curve is determined from the plurality of intersections, and the end point of the first offset curve is extended to the target intersection, and the start point of the second offset curve is extended to the target intersection. The method provided by the embodiment can be used for quickly connecting the offset curves.

In some embodiments, the connecting processing is performed on the offset curves corresponding to the boundaries to obtain the target suspended ceiling area, and the method further includes:

and in the case that the first borderless curve and the second borderless curve do not have an intersection point, supplementing lines between the first offset curve and the second offset curve.

In some cases, the offset curve is not a straight line, or is parallel, etc., and there may be a case where there is no intersection between the first borderless curve and the second borderless curve, and at this time, a line may be supplemented between the two so that the two may be connected.

In some embodiments, the supplementing line between the first offset curve and the second offset curve comprises: a line segment is disposed between the end of the first offset curve and the start of the second offset curve. The patch cord can be connected between the end point of the first offset curve and the start point of the second offset curve by adding a line segment.

Through the connection mode, the corresponding offset curves of the boundaries can be connected into a closed contour, the closed contour can be the contour of the target suspended ceiling area, and the target suspended ceiling area can be obtained through the contour.

After the area of the multi-stage suspended ceiling is drawn, the out-of-plane parameters (suspended/elevation) of the area are set, then the target stacking members are placed on paths (target boundaries) among the areas, and finally the expansion and contraction of the relevant area are influenced through the parameters of the target stacking members. Because the stacking component can solve the staggered layer scene in the house-hold design, the flow can be mainly divided into three parts (corresponding to three columns in fig. 9 respectively):

First column, staggered layer: i.e. to let there be a height difference between the different ceiling areas. The method mainly comprises two steps: drawing a stacking area (i.e., drawing zoned multi-level ceilings) and setting an area down-hanging/elevation (setting different heights for each ceiling area).

Second column, generating target stacking component: entering a stacking component generating tool, selecting a path (target boundary) for generating a stacking component, selecting a stacking component template in a stacking component library, adjusting and adapting parameters such as length, width, height, position orientation and the like of the stacking component, and generating a target stacking component.

Third column, realize overlap joint effect: entering area extension calculation, determining suspended ceiling areas on two sides of a stacking component path (target boundary), respectively adjusting the sizes of the suspended ceiling areas on two sides according to parameters of the target stacking component, and realizing the staggered effect of different design areas, specifically calculating an affected area (namely the suspended ceiling area needing telescopic treatment), then expanding the suspended ceiling area, and then continuing to design on a facing area of the suspended ceiling area, such as setting materials, lights and the like.

It can be appreciated that in the home-decoration scenario, the main processing of the ceiling region expansion is region expansion, and for example, the region expansion may be implemented by using a region expansion design processing module (which may be used to execute the stacked ceiling generating method provided by the embodiment of the present disclosure).

In addition, in the region drawing operation, a region design with a topo (topological) structure may be provided, and this region design may generate either a regular region (a pure geometric region, for example, a rectangular region) or an irregular region (a complicated irregularly shaped region), specifically may be designed according to circumstances.

In one embodiment, for the second ceiling region (inner/outer contour to be telescoping), each boundary (halfsedge) of the second ceiling region may be represented using a half data structure, and boundary information (halfsedge info) corresponding to the boundary may be determined, where the boundary information may include an initial boundary of the boundary

(3) If the first boundary itself (baseCurve) is a circular arc, the radius of the circular arc is added to the offset (offset) counter-clockwise, the radius of the arc is subtracted by an offset (outer contour) clockwise it is the outer expansion inner contour that is the inner contraction all according to isCCW (iscounter-clockwise, whether counterclockwise) and constructing an offset curve (offsetCurve) of the first boundary according to the initial and ending angles of the first boundary and the new radius;
