A data-triggered observation method for automatic follow-up of visible points

Abstract

A data triggering-type observational method based on automatic visible point following comprises the following steps of (1) acquiring simulation data from a bus, and classifying the simulation data into periodicity data and aperiodicity data to be cached; (2) conducting possible data difference treatment for the periodicity data to ensure an updating time of two adjacent groups of data to be less than 30ms; and for the aperiodicity data, reading all data memory which is not marked as read and corresponds to the earliest simulation time, and uniformly setting key time of a simulation system; (3) judging whether the aperiodicity data is acquired at the visualization simulation time again or not, judging the window compatibility if the aperiodicity data is acquired again, determining whether to add a window or not according to the compatibility, and setting a corresponding camera position and an observational angle variation strategy; and maintaining the window camera variation strategy if the aperiodicity data is not acquired again; and (4) displaying a scene according to the periodicity data of the current time as well as the set window and the camera strategy.

Description

technical field [0001] The invention belongs to the technical field of visual simulation, and relates to a method for three-dimensional display and observation of visual objects in a simulation system. Background technique [0002] With the development of simulation technology, the simulation system is getting bigger and bigger. Pure digital simulation lacks intuition, and the huge data is not conducive to analysts' data analysis. The 3D visualization technology provides an effective means for the intuitive display and data analysis of the simulation process, and realizes the simultaneous progress of perceptual display and rational analysis. However, due to the different time periods of the simulation deduction, the display areas, entities, events, etc. that users pay attention to are not the same. At the same time, with the expansion of the simulation area, the number of objects, types of interactive information, and the number of interactions increase significantly. In re...
