Hi all. I'm into 3D Modelling and Rendering as my hobby and I just have to post this image I made for no reason at all other than it cheers me up ever time I see it. If it can do the same for you then it's worth posting.
This is not a drawing, it's an actual 3D world populated with objects that all have their own influence on everything else. A computer simulated breeze bows from more than one direction just like a breeze in the real world.
So the smoke is not something I setup to blow in a specify direction. It's blowing where it should go according to the simulation and the parameters of the 3D world I set.
