As a preferable aspect of the present invention, the step of determining whether the two splitting points are within the filling area representing the edge member in step S1 specifically includes the steps of: clicking a screen on a graphical interface to select two split points; and respectively making positive rays along the X axis for the splitting points, solving intersection points of the rays and the boundary of the filling area of the edge member, and if the number of the intersection points is odd, enabling the splitting points to be in the filling area of the edge member.
As a preferred scheme of the present invention, in step S2, it is determined whether two splitting points are on the same wall of the building information model, and the method specifically includes the following steps: in the building information model, two ends of a wall and a wall-thick area are used as a rectangular frame, whether two splitting points are in the rectangular frame of the wall body or not is judged according to the coordinate positions of the two splitting points and the area position of the rectangular frame, if so, the two splitting points are in the same wall body of the building information model, and otherwise, the two splitting points are not in the same wall body of the building information model.
As a preferable scheme of the invention, the method further comprises the following steps: if the intersection of at least one of the two straight lines with the boundary of the filling area representing the edge member is greater than or equal to 3.
Example 2
A flow chart of an edge member splitting method based on a building information model is shown in fig. 1, and specifically includes the following steps:
s101 selects two points K1 and K2 within the filling area of the edge member GB1, as shown in fig. 2.
The user clicks a screen on a graphical interface to select two splitting points, the program analyzes the splitting points, rays are respectively made along the X axis in the positive direction of the splitting points, intersection points of the rays and the boundary of the filling area of the edge component are obtained, and if the number of the intersection points is odd, the splitting points are in the filling area of the edge component. When both split points are in the same edge member fill area, the next step is performed, otherwise the split points are reselected.
S102, judging whether K1 and K2 are in the same unique wall body of the building information model.
Making a rectangular frame by using the two ends and the wall thickness of the wall in the building model, and judging whether the splitting point is in the rectangular frame of the wall; considering that the split point may be in more than one wall, it is necessary to record that the split point is in the rectangular frames of several walls at the same time; the wall bodies containing the splitting points at the same time are different from each other in the connecting direction of the starting point and the end point, and in order to ensure that the splitting reference is unique and accurate, the edge members are split only when the splitting is performed in the same unique wall body of the building information model.
S103, two straight lines L1 and L2 which are long enough are made, and respectively pass through two splitting points and are perpendicular to a connecting line of end points of the wall, and a schematic diagram of intersection points P1 and P2 of the straight lines L1 and the boundary line of the GB1 is shown in FIG. 3.
The straight lines L1, L2 of S104 divide the edge member surface area into three filling surface areas.
The invention can obtain point sets stored by each vertex in sequence from the edge component filling area, and firstly, the intersection points P1 and P2 of the boundary line of the straight line L1 and the GB1 are obtained; the program judges that a point P1 is on a Line1 connecting pt3 and pt4, and a point P2 is on a Line2 connecting pt5 and pt 6; as can be seen from FIG. 3, GB1 is formed by point sets sequentially connected pt 0-pt 7, line1 is formed by pt3 connecting pt4, pt3 as the starting point and pt4 as the end point; line2 is formed by connecting pt6 with pt5, with pt5 as the starting point and pt6 as the ending point. Because the index of the starting point pt3 of Line1 in the GB1 point set is earlier than pt5, the point set of the first edge component GB1a after splitting is in order from point pt0 to the starting points pt3, P1, P2 of Line1, the end points pt6, pt7 of Line2, and the point set of the second edge component GB1b is in order from P1, the end point pt4 of Line1, the starting points pt5, P2 of Line 2.
The program judges that the straight line L2 can split GB1b, and the splitting method is the same as that for splitting GB1 by L1. As shown in fig. 4, two intersection points of the L2 split edge component are P3 and P4, and the split edge component is denoted as GB2a (points of GB2a are P1, P3, P4, and P2 in order) and GB2b (points of GB2b are P3, pt4, pt5, and P4 in order).
S105, removing a filling surface area between the two straight lines to finally obtain the split edge member.
And the program judges the three edge components GB1a, GB2a and GB2b which are split finally, and calculates the number of the top points of the surface area of the split edge components which are overlapped with the points P1, P2, P3 and P4. And deleting the area with the coincident points from P1-P4, thereby obtaining two split edge members. As shown in fig. 4, the edge component GB2a includes points P1, P2, P3, and P4, so that GB2a is deleted, and GB1a and GB2b are added to the drawing, and the split edge component diagram is shown in fig. 5.
The two straight-line edge component surface area splits may be more than three, so the following constraints need to be made:
assuming that the intersection points of L1 and the boundary of the edge member are P1, P2 and P3 … …, the distance between the intersection points and Q1 is calculated, two points closest to Q1 are reserved, and since Q1 is in the surface area of the edge member and the edge member is a surface area formed by a closed loop, the two points closest to Q1 are only required to divide the edge member into two. The same screen was done for the intersection of L2 with the edge member boundary.
Firstly splitting the surface Area of the edge component into Area1 and Area2 by using L1, and recording two intersection points P1 and P2 of the edge component split by the L1; then L2 is used for splitting Area1 or Area2, and two intersection points P3 and P4 of the L2 split edge component are recorded; and calculating the number of the superposition of the top points of the surface area of the edge component after the splitting and P1, P2, P3 and P4. And deleting the area with the coincident points from P1-P4, thereby obtaining two split edge members.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
