Dam not only has a large capacity to alleviate water shortages, especially during the dry season, which improve hydroelectric capacity, but also plays a major role in the river ecosystem. The dam has a significant effect on the improvement of our aquatic environment and the protection of the ecological system.
Dam not only has a large capacity to alleviate water shortages, especially during the dry season, which improve hydroelectric capacity, but also plays a major role in the river ecosystem. The dam has a significant effect on improving our aquatic environment and protecting the ecological system. This article addresses the three-dimensional model of dams and discusses OpenGL modeling, lighting, material, model transformation, perspective transformation technologies for Achieve visualization of the dam, Display the dam through concrete examples.
It has been thousands of years for humans to conserve the water resources of the dam. At the end of the 20th century, there have been 240 countries in which about 75 flood control countries are mainly dependent on dams, and 90% of electricity comes from hydropower. Without a doubt, dam building, hydroelectric power have become an important part of social civilization. The construction of dams can not play a single role, except for flood control, irrigation, shipping, tourism, aquaculture, etc., the most important aspects are water supply and power generation. It is one of the important roles for morden dams to control floods and then convert them into available water resources. In particular, the contradiction of water resources in modern society is very visible, therefore the construction of dams is very important to solve water problems.
For example, in China, freshwater resources are scarce. The ecological environment has been devastating as a result of natural disasters. On the one hand, flooding occurs frequently; on the other hand, drought is also severe. Therefore, the fundamental solution of these problems are inseparable from the construction of a number of dams to increase the regulatory capacity of natural water resources . For this reason, research on a rapid three-dimensional visual simulation of prey is considered quite significant.
In recent years, computer systems, the continuous development of input and output graphics devices and computer graphics software, which create a condition for computer-aided design. The Open Graphics Library (OpenGL) is a high-performance, cross-platform 3D graphics software development system that provides strong design capabilities in two- and three-dimensional graphics. There are many factors in OpenGL for curves and quadratic drawing surfaces, such as the NURBS Curve. It is in this work that we can visualize the dam by OpenGL technology.
