Optionally, the angle of the target model in the visualization window is adjusted by adjusting the observational camera coordinates according to a vector difference between the start point coordinates and the end point coordinates. The observation camera is a virtual camera of the computer device, and is used for displaying the obtained image to the visualization window. Specifically, the method comprises the steps of obtaining the component vectors of vectors connecting the starting point coordinates (x-axis and y-axis coordinates) and the end point coordinates (x-axis and y-axis coordinates) on the x-axis and y-axis, and setting the coordinates of the camera through the component vectors to achieve the effect of rotating the camera, so that the effect of adjusting the angle of the display model is achieved.
