How are you going to tell which slave to follow which master?

the fltk examples demonstrates creating a thread to pump messages for
FLTK, which I assume is also what you need to do to get messages from
X or to a Qt window

Cluster of points driving another cluster of points

[Olivier Jeannel]

I don't know how to do that :

Let's say I have a grid of 10 particles moving in a simultion (Master).

Let's say I create another grid of 100 particles (slaves).

I want those 100 particles to follow in position, rotation and scale the 10
master particles.
I don't want the slaves to get the position of the master, I want the
master to behave like the center of the slaves chunk/cluster.

Not sure I'm clear.

Update Referenced Material Library from any scene?

[David Saber]

Hi all!
In the doc it is said there should be a "master scene" in which all 
materials in the referenced material library should be managed. Is it 
possible to escape this requirement, and have any scene being able to 
update an external MatLib?

Thanks,
David

@ eric : Slaves are taking the closest master.
@ Simon no, one cluster of slaves is like "parented" to one master.
A sort of multiply by  matrix
The closest slaves particles get their SRT multiplied by the matrix of
their respective slave.

Re: Cluster of points driving another cluster of points

[Simon Reeves]

Or do you want all of the slaves to using the average position of all the
masters?

Re: Cluster of points driving another cluster of points

[pedro santos]

So for each point in cloud A you want the same corresponding(i) in cloud B
to be the scaling and rotation pivot? Do you additionally want it to be
position driver?

I don't know how you're applying the transformations, but basically just
center A ones on B ones: cloudA[i].position *-* cloudB[i].position ||| then
apply Scale and Rotation to cloudA[i ||| then cloudA[i].position *+*
cloudB[i].position
if it's just for scaling and rotation.

Images, images save lives :D


cheers

Re: Update Referenced Material Library from any scene?

[Rob Wuijster]

A master scene is kinda vital to a healthy production workflow, but imho 
you should avoid referenced material libraries.

They're flaky at best, and when things go wrong they go horribly wrong.

We tried a couple of times to use the feature, but every time ran into 
issues across scenes or renders.


but ymmv. ;-)

you can also use compounds now which can be handy
