Abstract

The invention is applicable to the technical field of electronic sand tables, and provides an object dynamic display method and device for a three-dimensional virtual sand table and terminal equipment, and the method comprises the steps: determining a target object region in a frame animation picture sequence of the three-dimensional virtual sand table, setting the target object region into a transparent channel format, and obtaining a picture sequence with a channel format; shielding the frame animation picture sequence by the picture sequence with the channel format to obtain a target objectimage sequence only retaining the image of the target object area, wherein the target object image sequence is in one-to-one correspondence with the frame animation picture sequence; and when the frame animation picture sequence is played, determining a target object area of the frame animation picture currently displayed by the three-dimensional virtual sand table according to a corresponding relation between the target object image sequence and the frame animation picture sequence, and adding a dynamic effect on the target object area. According to the embodiment of the invention, the dynamic effect of the target object in the three-dimensional virtual sand table can be accurately displayed in real time.

Description

technical field [0001] The invention belongs to the technical field of electronic sand table, and in particular relates to a method, device and terminal equipment for dynamically displaying objects in a three-dimensional virtual sand table. Background technique [0002] 3D virtual sand table, also known as 3D digital sand table or 3D electronic sand table, is a 3D electronic model based on basic geographic information data, model data, attribute data, and graphic data and established by various 3D simulation methods. It is used in urban planning, military exercises, engineering design, agricultural planning, environmental governance and other fields. [0003] Among the existing 3D virtual sand table display technologies, it is an excellent 3D virtual sand table display technology because it can display high-precision images and has low requirements on the performance of the operating system when the sequence frame animation display method is adopted. The sequence frame anim...
