Embodiment Construction

[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Aiming at the problem of huge amount of data computation in three-dimensional modeling, the present invention adopts a layered and block method to solve this problem by establishing a multi-resolution pyramid and performing block processing. The purpose of adopting this strategy is to reasonably reduce the amount of data involved in terrain rendering, thereby reducing and simplifying the time complexity of the algorithm.

[0044] The reason why the present invention adopts layered block pyramid structure is:

[0045] refer to figure 1 , is a schematic diagram of data display in the embodiment of the present invention.

[0046] When the user's viewing angle moves from far to near, the range that the user sees will decrease...

Abstract

The invention provides a method and device for delaminating and blocking data in three-dimensional modeling, in order to solve the problem of large data computation amount during three-dimensional modeling. The method comprises the following steps: determining the lowest layer and the highest layer for data delamination, and determining the number of data layers, wherein the resolution of the lowest layer is lowest, and the resolution of the highest layer is highest; determining the number of data blocks on each layer and the size of each data block; and calculating the information forming the data block for each data block on each layer according to latitude and longitude information. By constructing a multi-resolution pyramid and carrying out blocking treatment, the method can be used for reasonably reducing the data amount for topographic plotting, thereby lowering and simplifying the time complexity of an algorithm.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a data layered and block method and device in three-dimensional modeling. Background technique [0002] 3D modeling is often used in the processing of geographic information data, and has application value in many fields such as oil field development and geological research. From the perspective of process, 3D modeling is a method of building a three-dimensional model in space; from the perspective of result, simply speaking, the established model has a sense of space and can see up, down, front, back, left, and right. Among them, "dimension" is the basic concept of geometry and space theory. Each factor that constitutes space is called one-dimensional, such as a straight line is one-dimensional, a plane is two-dimensional, and ordinary space is three-dimensional. Three-dimensional space is the so-called three-dimensional space, which is a space composed of t...
