Pipe Smoke Simulation

In this short post I am going to talk about how we used and inte­grated built-in XSI par­ti­cle sys­tem to make smoke sim­u­la­tion for our pipe smoker char­ac­ter in Vishka Studio’s cur­rent short ani­mated movie Baran.

Please notice that I’m not going to talk about dynam­ics here, I just want to talk about the look of smoke sim­u­la­tion here.

At first I started to look what XSI gave us to make smoke! After a short time I decided that there is no built– in appro­pri­ate fluid sys­tem — at least for mak­ing phe­nom­e­non like smoke– I’m not going to com­plain about XSI, but there are many smoke sim­u­la­tion tools in Maya, Hou­dini and plu­g­ins like FumeFX for 3ds max. Maybe the devel­op­ers of XSI just wanted to stick to the ani­ma­tion part of XSI which is the excel­lent sec­tion of XSI in my opinion.

I don’t want to stick so lim­ited num­ber of soft­ware because I’m at first a soft­ware engi­neer but there is some lim­i­ta­tion and dif­fi­culty in our process to export ani­ma­tions and, character’s mesh trans­la­tion between dif­fer­ent 3D plat­forms. So after some talk­ing with my tech­ni­cal super­vi­sor Mr. Ghobady we decided to make the entire sim­u­la­tion com­pletely in XSI.

The point was, we may have the same result as flu­ids do but with some tricks in ren­der­ing and simulation.

With much more par­ti­cle rate and smaller size we have the first step of mak­ing smoke. The ren­der­ing result is not much inter­est­ing but after apply­ing another built-in XSI tool –com­posit­ing Quar­ticBlur fil­ter– we have the final smoke result. Eas­ily

First try with default par­ti­cle parameters.

Sec­ond try with more par­ti­cle rate and smaller size.

The same sim­u­la­tion with applied Quar­tic blur.
