介绍了钻井模拟器图形程序在压井作业中实现模拟火焰燃烧效果的技术和过程。在粒子系统的基础上,基于OpenGL的火焰模拟使得效果更真实,场景更逼真。模拟过程中采用BillBoard技术实现粒子立体影像,节约了资源,提高了运行速度;采用纹理融合技术,火焰粒子随时间的推移,发生颜色渐变和纹理变化,使得燃烧效果更加真实。 This paper introduces the technology and process of drilling simulator graphics program to simulate flame combustion in well killing operation. Based on the particle system, the flame simulation based on OpenGL makes the effect more realistic and the scene more vivid. The use of BillBoard technology in the simulation process to achieve three-dimensional particle images, saving resources and improve the speed of operation; the use of texture fusion technology, flame particles over time, the color gradient and texture changes, making the combustion more realistic.
