前几天,将
"Target-Driven Smoke Animation" on the GPU投给了WWW.GAMEDEV.NET的每日一图.（Image of the Day ）。
http://www.gamedev.net/community/forums/topic.asp?topic_id=392793收到的评论还不错。摘其中一条：
It looks amazing. Definately something that has potential. I tried the link to your website, and it didn't work. I googled it, and it came up, but it was in chinese... is there an english version? Having google translate it didn't work out too well
--------------------------
My goal was to simulate the Navier Stokes equations using GPU and then extend that approach to implement "target driven smoke animation"(siggraph 2004) in 2D. Given a sequence of target images, the method can generate a smoke simulation in which the smoke is driven towards each of these targets in turn, while exhibiting natural-looking interesting smoke-like behavior.For 2D simulations on a 256X256, my animation runs at 30 FPS rate on the NVIDIA 6600GT GPU.
