Hi Dominik,
How about splitting it into two simulations? You can source the fluid
from your desired location outside the sphere, when particles collide
with the sphere you kill them. Then in SOP's you build a new source from
the particles that die on the current frame, but slightly displaced by
the normal of the sphere, so they are inside. Then in the second
simulation you can source from those points and have this fluid collide
with the inside of the sphere.
The cool thing about this, is that it can work in any situation with any
piece of enclosed geometry :-)
Cheers,
Nick, be Nimble

Hi,
I started to work on the integration of Fabric Splice into Houdini:
https://vimeo.com/126371420
A kind of portable VOP graph if you will ;).
My free time on this project is very limited and I think it could evolve
into something very interesting. The github repo will be public very soon,
but if you are a developer with good Houdini knowledge and would like to
contribute just let me know !
Cheers,
Guillaume
Does anyone use Amazon's Houdini rendering? Is it still active? I have
searched and searched and searched the Amazon AWS website after signing up
and can find exactly no mention of Houdini or Side Effects.
http://www.sidefx.com/images/stories/news/HQueue_Cloud/hqueue_cloud_guide...
That document is wildly out of date, as are the ROPs when set to Cloud.
Is this still a thing?

Hi,
does anyone have experiance with importing openFoam simulation caches
into houdini for rendering?
if so any tips or advice would be greatly appreciated
thanks
Miles
I just read the article on the site and wow, what a career Janet!
What a luxury to be able to retire at age 50 ;-)
Enjoy whatever comes next.

bloody rich test format....geez

Here is chinny describing sticky key: pivot / snapping interaction
https://www.youtube.com/watch?v=8jWfwJtiysQ
So to rotate a cube 45 degrees about a corner leaving its center
unchanged:
I'd hold *C*, *alt* and* ctrl* to activate rotation, manipulate the
temporary pivot and snap to points
I'd *click once* on the corner i wish to rotate around then *release alt
and ctrl *as C remains depressed the app returns to rotation mode
holding *shift* i could then rotate around the *selected axis* in 15
degree
increments.
the whole operation is two mouse clicks and a few keyboard modifiers,
plus
the application reverts to my previous tool when i release the C key due
to
the entire operation taking place using sticky keys. Plus the temporary
pivot evaporates leaving my original pivot unchanged. All in im done in
about a second. and never take my eye of the element im modifying.
some really handy ones. ( these are misleadingly close to procedural
operations, but presented efficiently )
any transform ( which is always visible on the right ) can receive a
relative offset with math operators:
http://softimage.wiki.softimage.com/xsidocs/interface_SettingValuesforPar...
these are not permanent procedural expressions and they don't require
you
go hunting for a property page
so for 10 cubes all at random positions in X i could select the X axis
numeric transform and type 10+
they will all have 10 added to their X position transform
l(-5,5) would linearly arrange them from -5 to 5 based on order of
selection etc..
but the big point is these require no extra nodes, no opening panels,
nothing beyond what is always visible on the screen and 3 to five clicks
] + middle click = split edge with edgeloop
the viewport undo stack is independant from the regular undo stack: alt
+ z
ill just end up summarizing the documents if i continue down this path.
which can be found here by the way:
http://download.autodesk.com/global/docs/softimage2014/en_us/userguide/in...
Im by no means saying Softimage's approach should be seen as the
pinnacle
of what can be achieved or even that they warrant replicating, but the
core
commitment to* eliminating unnecessary clicking and maintaining focus on
the task at hand* by reducing the dependence on extraneous cluttered
panels
resonated with artists and technicians alike.
Craig: the uv tools in soft were workable, poly reducing
<http://download.autodesk.com/global/docs/softimage2014/en_us/userguide/in...>
features were pretty good, normal baking was nice ( ultimapper
<https://vimeo.com/10007237> go to 50min ) and attribute transferring
(gator
<https://www.youtube.com/watch?v=wcGwvc2VCkk>) in general was kind of
cool
for an artist friendly app, these are all pre ICE workflows and not
necessarily something houdini would benefit from.
Sorry i dont have softimage available anymore, i quit the facility that
purchased it, otherwise i would be able to provide more targeted visual
demonstrations.
dont a bunch of ex soft guys work at side fx these days?
