Problems solved by technology
[0004] 3D visualization technology focuses on the construction, expression and attribute-space analysis of 3D spatial entities, but the process of establishing a 3D model is a complex and time-consuming process of multiple judgments and multiple processing. Human-computer interaction operation, moreover, the various solid units of the 3D model are closely related, even if a control point on a boundary surface of a unit changes, the corresponding boundary surface, the corresponding solid unit, the adjacent one or several The entity unit must change
But so far, there is no successful precedent for the organic combination of the two

Embodiment Construction
[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0036] A landslide is taken as an example below. For the convenience of description, the two-dimensional schematic diagram in Figure 1 is used instead of three-dimensional for illustration, and the numerical simulation software is Flac 3d software as an example. Other software works similarly.
[0037] Also refer to figure 2, the implementation method of the integration of the three-dimensional visualization technology and the numerical simulation technology of the present embodiment first establishes the boundary surfaces of each geological unit of the landslide based on the three-dimensional visualization software, and obtains the coordinates of each boundary surface and each control point on the boundary surface: in...

The invention discloses a three-dimensional visualization and numerical simulation fusion realization method and system. According to the method and system, the boundary surfaces of entity units on athree-dimensional model and the three-dimensional coordinates of control points on the boundary surfaces are researched and determined; the obtained coordinates of the control points are set to be monitoring points in a numerical simulation process, so that the control points of three-dimensional visualization can be in one-to-one correspondence with the monitoring points of numerical simulation;the new three-dimensional coordinates of the control points in different time points in the future can be obtained according to the new positions of the monitoring points at different time steps; andtherefore, a grid connection between the three-dimensional visualization and numerical simulation can be realized, the 3D entity model of a research object at different time points in the future canbe obtained, and better technical support can be provided for the process simulation of the research object.
