利用粒子模式模擬火災現象

Abstract

在電腦圖學的領域裡, 火焰的模擬一直是極具挑戰性的問題. 在本篇論文 中, 我們探討火焰的模型. 因為火焰是紊亂且不穩定的, 我們利用粒子模 式來描述火焰的形狀. 這個模型也模擬了從小火舌到巨大火焰的擴散過 程. 此外, 為了更逼真的視覺效果, 我們也模擬了火場中整體照明度的變 化情形. In computer graphics, the simulation of flames is still a challenging problem.We discuss the modeling of fire in this thesis. Since the fire is turbulent andnon-steady, we adopt the particle system for describing the shape of flame. Thismodel simulates the spreading process from tongues of flame to conflagration.We also give the variation of the global illumination in the fire-disaster areafor more realistic visions.
