hi, guys thanks for taking your time to reply
to SYmek, thanks for making the point really clear to me and is exactly the piece of info I am seeking for
to chrism, thanks for pointing that page to me, I came over that page once, and must be blind without notice the section on openCL and video card info before

I am sorry didn't make my question clear,,
on smoke solver advanced tab, there is use openCL checkbox connect to its inner microsovler to enable gpu calculation. on FLIP solver, there is not such option provide, thus If I like to use gpu, I have to edit the FLIP solver HDA and go inside to switch those microsovler one by one. Is there any reason, why default FLIP solver provide without use openCL option.
I guess, its not setup because not suggested?? I am not sure the reason, that's what I like to know. Thank you.
I am on ubuntu64 by the way

hi, the new h12 flip solver contains many microSolver with use openCL off by default without providing an option on flipSolverDop to enable it. Does it comes with any insight not to use it??

being really busy for the past few days, sorry for the late upload. for hardware, oglRop with high aa seems to be jitter-free. However, with aa, it seems to render as sphere?? Which is not that big issue anyway, or I can live with mantra for best quality.
Thank you guys for help

hi, tamte and rafaels, I am really thankful for your help.
and yes, like you said, the problem is due to hardware render and unantialiased issue, I test again with render as point via hardware(flipbook and ogl rop) and software. The software render does not show this problem anymore. The hardware render has those point particle jittering. I will try to post video clip of this when I get home. Is there any solution to this. I thought maya playblast works fine (not very sure!!) or I just have to use software render in this case.
guys, thank you again

In a simple setup as sphere for particle source, with gentle downward force -.3 for Y and a wind pop with subtle noise. Now the particle falls with turbulence like wind pattern. Flipbook this setup, the particle jitters while it moving slow.
It seems the downward force is fighting against wind force? any idea to get rid of this?
please see my file, any help is appreciate.

Hi, on partilce fluid object dop, there is the coordinate system tab.
on manual, it clearly states what every parameter dose, but how would I apply this in practice? I have searched both forums and found no answer. could anybody point me some direction in its use and how, please ..

hi, in geometry sop, by right clicking over any sop node. It could be save as rib in H10. It seems not working in H11 anymore. Although I can chose rib file format from file output filter. It however outputs as outputfile.rib.bgeo. Does this function get deprecate?
thank you

Technical Discussion » possible bug, sprite texture size and offset on H11?
- jorosy
- 47 posts
- Offline
hi, I have a long strip sprite image, and try to “frame” by sprite pop texture size and offset. It is a simple setup of location pop followed by a sprite pop.
It works fine on H10, but not on H11. Could someone please help me to confirm if this is bug.
the attatchment file include,
* sprite image file.
* both working and not woking screen shoot on H10 and H11.
* H11 setup file.
Thank you
—————————
H11 the sprite image does not response to sprite texture size and offset. It skews into square
—————————
same setup in H10, it appears normal

Thank you wolfwood for putting up that information.
Actually, I did came over that post before I asked.
I am not familar with api or c++ stuff, thus when I saw that number behind state, I thought it was memory address ??
Think I am wrong, if thaken out the ox code from number, it seems represents the pstate number.

wao, thank you Jesse for your time to post this, it is very helpful and clear to me now.
Am I allowed to follow up a question as how would you know which property works under different state, as jeff mention in above post.
It seems obscure for some properties under certain states.
thank you

hi, I am looking at help file on pop creep example, and found creep does actually change pstate.
and I have came across the following two threads, whcih seems the different pstate will have different attribute, property acts (inc force?) on pop
so, what does those two state means and what they are?
pstate 32768 (sliding splash example)
pstate 16 (turn pop creep stuck to 1)

the problem is solved, I got answer form od forum. That I just didn't realize gas match field, just match existing field without create one. So I use gas calculate to copy data and match field to match its size.

Hi, jeff, wao,,, thank you, thank you for your time to make this for me, that is really kind.
May I ask, wouldn't the collision dection to sop is more computational than just trying to re-implenment a closed boundary volume??, especially on millions of particle fluid. I am a newbie trying to make a throught understanding of all this. I think I am thinking in wrong direction.
