Referring to FIG. 1 , this embodiment provides a method for previewing a curtain wall, including the following steps.

Step S100, generating a visualization window of the computer device.

Exemplarily, the above-mentioned visualization window is implemented by the MaskPanel control built in the Winform application, so that the user can preview the finished curtain wall through the visualization window.

Step S200, acquiring the target curtain wall and the initial grid lines. The initial grid line is selected by the user. After the user selects the initial grid line, the preview method provided in this embodiment can insert the outline of the sub-curtain wall between the selected initial grid lines. Optionally, the initial grid lines can also be used as references to allow the user to better understand the spatial relationships of the displayed model. Optionally, the number of initial grid lines is greater than or equal to two.

Step S2201, acquiring initial grid lines. In this embodiment, the initial grid line is used to define the division range of the subsequent segmentation model, or as a reference line to assist the user in understanding the spatial relationship of the target model.

Step S2301, judging whether the number of initial grid lines is greater than or equal to a preset number. In this embodiment, if the initial grid lines are used to define the division range of the subsequent segmentation model, the preset number of initial grid lines may be set to two.

Step S2401, when it is determined that the number of the initial grid lines is less than the preset number, perform step S220 again. When it is determined that the number of the initial grid lines is greater than or equal to the preset number, step S300 is performed.

Referring to FIG. 3 , optionally, step S200 includes steps S2102 to S2402.

Step S2102, acquiring the contour line of the target curtain wall.

Step S2202, generating a first layer according to the outline of the target curtain wall.

Step S2302, acquiring the initial grid lines.

Step S2402, generating a second layer according to the initial grid lines.

Steps S2102 to S2402 allow the user to select different layers for display or modification according to actual needs by setting the contour lines and initial grid lines of the target curtain wall into layers.

Continuing to refer to FIG. 1 , in step S300 , a sub-curtain wall contour line of the curtain wall is generated according to a preset segmentation model.

The preset segmentation model in this embodiment can divide the curtain wall into a plurality of sub-curtain walls according to the built-in segmentation algorithm. The dividing line generated by the dividing model is the contour line of the sub-curtain wall. This embodiment does not limit the segmentation model used in the preview method. Exemplarily, the segmentation model may be an unfolded surface segmentation model (develop a three-dimensional curtain wall into a plane curtain wall and then divide plane sub-curtain walls) or a three-dimensional segmentation model (directly divide a three-dimensional curtain wall into three-dimensional sub-curtain walls through a grid plane). Optionally, step S300 may include the following steps: acquiring the sub-curtain wall contour lines of the target curtain wall according to a preset segmentation model.

Step S6301: Adjust the size of the target model in the visualization window according to the current coordinates and volume adjustment parameters, and perform step S6101 again. There is a proportional relationship between the value of the volume adjustment parameter and the volume of the target model. Specifically, when the scroll wheel of the input device slides along one side, the volume of the displayed model increases, and when the scroll wheel of the input device slides along the other side, the volume of the displayed model decreases. In this embodiment, steps S6101 to S6301 can realize the zoom-in and zoom-out effects of the display model.

Step S6302, when it is determined that the input device performs a drag operation, update the coordinates of the end point of the input device according to the current coordinates after dragging. When it is determined that the input device does not perform the drag operation, obtain the coordinates of the start point and the end point when the input device performs the drag operation. Step S6302 can accurately obtain the coordinates of the starting point and the coordinates of the end point of the drag operation performed by the input device, so as to facilitate the subsequent adjustment of the position of the target model in the visualization window.

Step S6402: Adjust the position of the target model in the visualization window according to the relative positions of the start point coordinates and the end point coordinates, and perform step S6102 again. Optionally, the position of the target model in the visualization window is adjusted by adjusting the coordinates of the observation camera according to the vector difference between the coordinates of the start point and the coordinates of the end point. The above-mentioned observation camera is a virtual camera of the computer equipment, and is used to display the obtained image in the visualization window. Specifically, by obtaining a vector connecting the coordinates of the starting point and the ending point, and adding the vector to the coordinates of the observation camera (in C#, the observation camera can simulate the actual loading effect of the display model by capturing pictures), adjust the Display the position of the model in the visualization window, and then realize the effect of adjusting the position of the displayed model.

Referring to Fig. 5, optionally, step S600 includes steps S6103 to S6403.

Step S6103: Monitor the click operation of the input device of the computer device in real time, so as to obtain the current coordinates of the input device in the visualization window, and use it as the coordinates of the starting point. Specifically, the input device is a mouse.

Step S6203, judging whether the input device performs a drag operation. Specifically, whether the input device is in a dragging state is determined by the ondrag function preset in the C# function library.

Step S6303, when it is determined that the input device performs a drag operation, update the coordinates of the end point of the input device according to the current coordinates after dragging. When it is determined that the input device does not perform the drag operation, obtain the coordinates of the start point and the end point when the input device performs the drag operation. Through step S6303, the coordinates of the start point and the end point of the drag operation performed by the input device can be accurately obtained, so as to facilitate the subsequent adjustment of the angle of the target model in the visualization window.

Step S6403: Adjust the angle of the target model in the visualization window according to the relative positions of the start point coordinates and the end point coordinates, and perform step S6103 again. Optionally, the angle of the target model in the visualization window is adjusted by adjusting the coordinates of the observation camera according to the vector difference between the coordinates of the start point and the coordinates of the end point. The above-mentioned observation camera is a virtual camera of the computer equipment, and is used to display the obtained image in the visualization window. Specifically, by obtaining the component vectors on the x-axis and the y-axis of the vector connecting the starting point coordinates (x-axis, y-axis coordinates) and the end point coordinates (x-axis, y-axis coordinates), the coordinates of the camera are set by the above-mentioned component vectors, so as to Realize the effect of rotating the camera, and then realize the effect of adjusting the angle of the displayed model.
