Embodiment 1

[0032] Embodiment 1: The present invention proposes a method for time-space simulation of curved surface process based on dynamic frame insertion technology. The dynamic process simulation of space-time curved surface means that it can keep synchronization in time and space, and the change process of curved surface in space can be real Three-dimensional and intuitive way to reflect. The process of time-space simulation is represented by a graph, that is, along the time axis, there is corresponding space model information at each time point, and the time coherence is a dynamic simulation of a changing process. See figure 1 .

[0033] Now take the example of simulating the change of land subsidence in a certain area in the ten years from 2000 to 2009, assuming that the original data obtained are discrete observation points on the ground and the ground elevation data observed every year, using the dynamic interpolation technology based on the present invention The surface proces...

Abstract

The invention relates to a dynamic frame interpolation technology-based curved surface process time and space simulation method. The method comprises the following steps of: starting simulating; constructing a simulation initial curved surface; initializing parameters of the curved surface simulation; constructing dynamic frame interpolation; and performing three-dimensional display on the curvedsurface constructed by the frame interpolation. The step of constructing the dynamic frame interpolation comprises the following steps of: calculating time values, calculating Z values of all points in a frame interpolation way, updating the Z values of all the points, and reconstructing again. According to the method, a curved surface space model is constructed in each frame interpolation time and is displayed by continuously calculating the time values until the last curved surface model is displayed. By the dynamic frame interpolation technology, the problem that the simulation process hops and is not fluent when a sample observation value is relatively limited, the conventional expression way of observation information is broken through, the observation information is expressed by pictures with curved surface time and space change, the change process is vividly and directly simulated, and the method is especially suitable for the simulation of the change process of the curved surfaces of groundwater simulation, ground subsidence and the like.

Description

technical field [0001] The invention relates to a curved surface time-space simulation method, in particular to a curved surface process time-space simulation method based on dynamic frame insertion technology, which is typically applied to dynamic simulation of land subsidence, groundwater change process and the like. Background technique [0002] We know that 90% of the information in the world is perceived through the visual system. In order to make the information expression more intuitive and easy to understand, graphics have become one of the most important media for transmitting information. Therefore, computer graphics has been greatly developed. Especially with the development of modern science and technology, 3D graphic visualization technology has been gradually developed and successfully applied in various industries. Three-dimensional graphics and images can express the objective world vividly and intuitively, and three-dimensional dynamic simulation technology ...
