Fuel Based Rocket Launch

Recommended Posts

I put together a fuel based version of the basic density based starter rocket launch scene.

This scene includes a couple of additions, that I have seen posted, here on OdForum, including Fencer's smoke drag, based upon distance from origin, and hand drawn velocity curves to encourage the smoke to travel along the curve shape.

The support nodes for the hand drawn velocity are shaded purple, in the DOP network.

Play around with the fit values on the gas wrangle to alter damping.

Increase popnet particle count to send more fuel into the system.

Increase popnet life to make fuel linger, longer.

Cool stuff!

2 Questions though. Why you use a Volume Source and gasenforceboundary for collsions? Shouldn't all this work by default? And is there a Reason you dont use OpenCl?

You'd think so, but in my experience, it does not all work by default. I wonder why they created the node (gasenforceboundary)...?

Open CL is memory bound and can fail in high memory usage scenarios. (Depends upon your hardware)

I made an attempt at "upresing" this fuel based rocket launch. Treating the original file as the a low resolution simulation does allow me to enable OpenCL. The uprezed version is on the right.

A 500,000 voxel low res source drives a 4,000,000 voxel upres.

Awesome, Thanks Atom for posting this.

I'm looking forward to digging in.
