Each decorating scheme has a furniture inventory and hard dress inventory, if after dress whole style changes firmly, will be changed into another One decorating scheme.After some furniture and position relationship change, also definition is changed into another decorating scheme.
The information in each room in user oneself house type is obtained by house type generation module 1, and is stored in user's room table, Room information include room number, house type numbering, room height, room area, room number of vertices and apex coordinate set, Door information and window information.Wherein the information of door and window can be stored in single table, and is associated by room number.House type generates When module 1 generates 3D models, following operation is performed to each room of user:According to the length of the summit calculated room in room and It is wide;The title of each window and the angle of window are set according to window list, the width of window is calculated according to the two of window summits;Arranged according to door Table sets the title of each door and the angle of door, and the width of door is calculated according to the two of door summits;According to each two top in room Point construction wall, sets the name of wall and the angle of wall, and the width of wall is calculated according to the two of wall summits;Same face wall is calculated to visit With the neighbouring relations of window.
Specifically, the method that finishing module 3 imports the furniture of some model room in user room automatically is as shown in Figure 4.
Step 1:Obtain the furniture list of model room;
Step 2:User's room information is read, the vertex set in room, window information and door are obtained by house type generation module 1 Information, and same face wall are visited the neighbouring relations with window;
Step 3:For user room, the finishing rule of output furniture and door, furniture and window, furniture and wall.
In the finishing rule of furniture and door, the horizontal range space of furniture and door and the minimum vertical with door have recorded Distance minspace and maximum normal distance maxspace, as shown in Figure 5 A, F1 represent furniture.Minspace refers to furniture in door After the left side or the right are put, it is impermissible for people between furniture and wall with the vertical range of the wall where door and walks.Maxspace refers to After furniture is put on the door left side or the right, allow Home Alone to have with the vertical range of the wall where door and walked not between wall It is problematic.
In the finishing rule of furniture and window, the horizontal range space of furniture and window is have recorded, and it is vertical with two of window Distance minspace and maxspace.Equally, minspace refers to after furniture puts, and is impermissible for the vertical range of the wall where window People walks between furniture and wall.Maxspace refers to after furniture puts, and allows a people to exist with the vertical range of the wall where window Being walked between furniture and wall has no problem.
In the finishing rule of wall for not containing door or window, furniture and wall, the water on certain summit of furniture and wall have recorded Flat distance space, and two vertical ranges minspace and maxspace with wall.Equally, minspace refers to furniture and put Afterwards, people is impermissible for the vertical range of wall to walk between furniture and wall;Maxspace refers to after furniture puts, it is vertical with wall away from Had no problem from allowing to walk between Home Alone tool and wall.
Due to there is two vertical ranges, so furniture when putting, has two new positions under different angles.
Step 4:According to finishing rule, the furniture in model room is put into user room one by one, if furniture is placed successfully, obtained Take bottom center coordinate of the furniture in user room;If violating finishing rule when furniture is placed, furniture is placed unsuccessful.
When swinging between new house, some furniture does not have direction, as furniture is shaped as square, hexagon, circle etc., faces The effect which direction is finally put is all.Some families have both direction, as furniture is shaped as rectangle, traverse, place vertically It is different to put effect.Some families have four direction, such as backed sofa, after a new position is defined, different directions It is different display cases, for example, if sofa leans on north wall, the left side or right side of door can be put, if put a left side, then the family With 3 angles, respectively 0,90,270.
For the furniture in some room, the furniture by door, window and wall is preferentially put;Model room it is to be put not by door, Window, the furniture of wall need to calculate new position according to the preferential furniture put.
According to door, as shown in figure 5, the putting position of furniture is likely located at a left OR gate right side, it is expressed as<Door numbering, the left side Or the right, if be placed with furniture>, when furniture to be put to certain side of door, the new position of furniture is<Door numbering, the left side Or the right,<Angles, furniture bottom surface centre coordinate>>.Such as possible putting position be present:<Door 1, the left side, yes>, yes Expression can be put, and no represents to put, then the new position of furniture is<Door 1, the left side,<Angles, furniture bottom center Coordinate>>.
According to window, as shown in fig. 6, the putting position of furniture is likely located at, window is left, window is right or window front, is expressed as<Window is compiled Number, the left side or the right or front, if be placed with furniture>.The length for the furniture put in front of window has two kinds of situations, is more than Or the width less than window, but the position of bottom center's point of the furniture calculated is the same.
According to wall, as shown in fig. 7, the putting position of furniture may be at the right summit space away from wall, the left summit away from wall At space, the middle of wall, it is expressed as<Wall number, by wall away from left apex horizontal distance space or by wall away from right summit water At flat distance space or wall center, if be placed with furniture>.
It is remaining not lean on the furniture of door, window or wall to put, calculated according to the possibility putting position relation between furniture The new coordinate of furniture to be put.
For example, to furniture in parlor:Sofa, tea table, cabinet for TV and wine cabinet;Wherein, set A={ sofa, cabinet for TV, wine Cabinet } it is the furniture set put by wall;Set B={ tea table } is the furniture set for not leaning on wall;Furniture in set A is put first, Then the furniture in set B is put.
For example, to furniture in dining room, placement regulation is:Dining room centre position is preferentially put and is in by the furniture that wall is put Preferential put;Do not put successively according to position relationship and the appropriate interval distance of the furniture with preferentially putting by the furniture that wall is put Put or be centered around in set A and put after the article of article all around;Such as dining table is first put, then put dining chair.
For example, to furniture in toilet, because the collector nozzle of closestool is fixed, shower house (or bathtub), bathroom cabinet (band Platform basin, bathroom mirror), closestool be all to lean on wall, but need first to place closestool, then movable shower room or bathroom cabinet lean on wall to other Position, to prevent causing draining inconvenient.
Step 5:To placing unsuccessful furniture, judge whether that by adjusting size success can be placed, if so, being adjusted to pair The size answered is placed, and otherwise abandons putting.
Such as certain desk, currently because size can not be positioned to greatly work(, inquire about whether the desk has small size replaceable.
Such as by three furniture F1 in the model room shown in Fig. 8, F2, F3 are imported into user room as shown in Figure 9. Fig. 9 room is rectangular room, has four sides wall Wall1~Wall4, has two doors Door1, Door2 and one on wall Wall1 There is an a door Door3 and window Window2 on individual window Window1, wall Wall2.
Furniture is arranged according to the position relationship in model room, calculates the new coordinate of furniture, such as currently used model Between in furniture F1, F2, F3 be that a word is put, in user room and a word put, there are four kinds to put effect:F3 is band side To, F3 angles are 0,90,180,270, then F1, F2 calculate according to F3 coordinate.
