Elbeem Fluids + Cycles motion blur
Closed, ArchivedPublic

Description

Hey,

This patch provided motion blur using elbeem bluids in cycles. The implementaiton is similiar to the Blender Internal render (using the speed vectors of the simulation as indication where and how much to blur).
I have had this patch laying around for quite some time and never had time to commit this.

Maybe someone likes to catch this up and bring the patch up to par with blender git head!

(I'm still upgrading + installing my system)

There is no patch attachted? :)

Sorry!

You should also note, that Cycles devs could complain about the location where I put my code ;-)

Can you upload the patch here https://developer.blender.org/differential/diff/create/ this allows developer to easily review the code?

Not sure how much useful this is, fluids are very likely to change topology, does this behave correct with such cases?

As I said, this replicates the bevahiour of the elbeem motion blur from blender internal. Nothing more, nothing less.

Elbeem generates speed vectors for every vertex for every mesh for each frame. And that you can use for motion blur (as it is already present in BI for 6 years or more).

I changed the patch to "archived" to reflect what I stated in my initial post.
This is not for review but for archieve.

Ehrm, it's kinda actual patch which has potentials. Why to archive it? And why not to move to differencial?

although I have no time and not enough knowledge to do it it would definitely make sense to update this patch. Thanks Daniel for providing it to make it possible.
