摘要:
针对经典粒子系统火焰模拟的真实性和实时性的关键问题,给出了一种新的基于粒子系统的火焰绘制算法,粒子属性的初始化由发射器确定,并对粒子的颜色、位置、生存期等属性的更新进行了优化,粒子的运动变化由低压点控制,粒子由四角面片表示,结合纹理映射技术进行三维火焰渲染,纹理采用分时间段映射来模拟火焰的燃烧过程,实验证明该算法模拟火焰的运动和外观效果真实,在普通的PC平台上利用标准图形系统即可获得实时的绘制速度.
Abstract:
Aiming at the key problems of the realism and real-time simulation of the classical particle system flame, a new flame drawing algorithm based on the particle system is given, the initialization of the particle attribute is determined by the emitter, and the update of the color, position, lifetime and other attributes of the particle is optimized, the movement change of the particle is controlled by the low pressure point, the particle is represented by the four-corner patch, combined with the texture mapping technology for three-dimensional flame rendering, and the texture adopts time-divided mapping to simulate the burning process of the flame. Experiments show that the algorithm simulates the movement and appearance of the flame, and real-time drawing speed can be obtained by using the standard graphics system on ordinary PC platforms.
