Embodiment Construction

[0056] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] At present, when dividing the grid of the water body in a more uniform way, that is, dividing the grid of the water body with a coarse grain size, if there is a prominent terrain at the boundary of the water body, the abrupt change point may be inside the triangular grid, and it will not be possible to The outstanding terrain is recorded, so that the details of the boundary cannot be simulated, resulting in a large gap between the drawn water body map and the actual figure.

[0058]Based on this, the water body vi...

Abstract

The invention provides a water body virtual visualization method and device in to the technical field of water body drawing. The method comprises the following steps of firstly, drawing an initial triangular mesh of a water body to be visualized; selecting a to-be-refined area from a visualized water body, then conducting triangular mesh refining on an initial triangular mesh corresponding to theto-be-refined area, subjecting the refined triangular mesh to treatment operation, acquiring the virtual visual water body, wherein the treatment operation comprises one or more of the following operations of three-dimensional operation, rendering operation, fluctuation effect drawing operation and water body illumination operation. The technical problem that in the prior art, the difference between the drawn water body graph and the actual graph is large due to the fact that a coarse-grained division mode is adopted is solved.

Description

technical field [0001] The invention relates to the technical field of water rendering, in particular to a method and device for virtual visualization of water. Background technique [0002] At present, when drawing the water body grid of rivers, lakes and reservoirs, it is often divided in a manner similar to uniform division. Specifically, when drawing, a single grid is used as a unit to draw, and the area of ​​each grid is compared with way to draw the grid. [0003] However, when drawing, a method similar to uniform division is often used, that is, a coarse-grained division method. No matter where in the water body, the number of divided grids is similar. However, there may be prominent terrain at the boundary of the water body. Then there will be points with sudden changes in elevation inside the grid, and it is impossible to use interpolation to estimate the elevation of the points with sudden changes in the interior, so that it is impossible to simulate the details o...
