abstract
The theme of this paper is based on the drawing and application of OpenGL
3D graphics. First of all, this article has a brief introduction to OpenGL, OpenGL
refers to the open graphics library, for the interactive three-dimensional graphics
development provides a good convenience. In addition, Also introduced the
OpenGL features and OpenGL3.1 new features. The second part introduces the
status of 3D simulation, three-dimensional simulation can reflect the real world
realistically, which leads to the topic of drawing and applying 3D graphics based
on OpenGL. The following is a detailed description of the three-dimensional
graphics rendering process: the establishment of programming environment, set
the basic library, add the corresponding function and drawing graphics. The last
part of this paper introduces the application of OpenGL in 3D simulation,
including the simulation of the real terrain of the key technology, simulation of
terrain generation process and the significance of three-dimensional simulation
application. 3D simulations can be applied to many scenes to simulate real scenes
to cope with various real situations.
