I have been working on final adjustments to my exhaust sim for speeding up the initial velocity and having it slow down as it lingers in the air. I have been experimenting with the POP drag node in the popnet, but it seems to be evenly applying drag to even the newly spawned particles. I want to find a way to have a decay rate where each particle will slow down over time or possibly a volume to pass through to control the speed of the particles. I did not make much progress in terms of this but the over all feel of the sim seems to be a little better. I plan to finish this by the end of class 8 so that I can spend the time between then and next class doing preliminary reference research for the turbo flames sim.
My pyro net has has the turbulence and drag removed as they were causing more of the particle smoke balls to pop through the smoke. I will probably add them back in later after I handle the speed issue of the smoke.
Not much has changed in the popnet either but I did add POPdrag which seems to handle the particles a little better than the drag force node did.
Currently, not much has changed in terms of the structure and look of the exhaust but possible solutions have been found and research into these solutions will happen during class 8.
