voxel velocity vs. emitter velocity
#1
Hi,

Since FumeFX is voxel-based, I understand that there is only one velocity vector for each voxel , let's call this velocity Vv. If an emitter intersects with a voxel and it emits smoke with velocity vector Ve, then how the final velocity is determined? in other words, how the emitter velocity affects the existing velocity? for example, if a voxel has a "large" velocity and then an emitter adds smoke with a "small" velocity, then would the final velocity be just a weighted average of both velocities? Also, is this related to "Free flow" in emitter properties?

Thanks,

Hello,

Each source adds velocity to the grid.
Free flow means that the fluid can flow through the source uniterruptedly.

Thanks for your reply...

Quote:Each source adds velocity to the grid.
does that mean : final voxel velocity = current voxel velocity + source velocity ??

Quote:Free flow means that the fluid can flow through the source uniterruptedly
as per flow "interruption", do you mean a source could collide with an existing fluid and interrupt its flow?

Thanks,

Hello,

The answer to both questions is yes.
If source is not a free flow, it definitely affects the fluid flow in the grid.
