I just hacked a quick Euler method.<BR/><BR/>However the rigid body code worked quite a bit better...... <BR/><BR/>As for 10k+ particles.... Yea I would think that a good sim would need 100k or more. With mulitcore support this should not be a huge problem. <BR/><BR/>Its also not all that optimized yet.bobhttps://www.blogger.com/profile/03594261943657857572noreply@blogger.comtag:blogger.com,1999:blog-15340997.post-41863510922973022682008-05-23T06:48:00.000Z2008-05-23T06:48:00.000ZFunny - it took me months to notice that the effec...Funny - it took me months to notice that the effector "Soft" actually does something!<BR/><BR/>I don´t get the sphere I played with to do a jump, - but it deforms well (Sphere is "copied" and rebuild out of particles then).<BR/><BR/>Cool - thanks Deltor.<BR/>And I started to do a glass fill animation again.

For the simple reason that I have other things to do and I don't want to release the code till version 1. But after that, then anyone can organize something like that. <BR/><BR/>I don't expect lots of animations or anything, but if we look at blender you will notice that the fluids are not used as much as people claimed they needed it. Its really a simple fact that physics based fluid flow according to the equations of motion, not according to artistic merit. It makes it less practical than people think. <BR/><BR/>But any pokes of "I am/want to use this" will help a lot. <BR/><BR/>Sorry its taken so long. But its not ditched and if i do ditch it I will release all the source code (GLP2 probably--and computable with AoI) so that someone else can "try" to pick it up.bobhttps://www.blogger.com/profile/03594261943657857572noreply@blogger.comtag:blogger.com,1999:blog-15340997.post-41739227991503268682008-05-13T12:32:00.000Z2008-05-13T12:32:00.000Z> I took the silence to mean that not that many fo...> I took the silence to mean that not that many folk are using/want to use it.<BR/><BR/>D'oh! This isn't the reason why I, personally, was silent. However, I can understand you. :/ "No bothering" could be taken as "no interest".<BR/><BR/>Ok, if you'd like some pressure to be applied, I'll do so. :D I really like your plugin so far and I'd really like to see further development. I agree with Harald (as he said many times before) that physics are a huge enhancement for AoI.<BR/><BR/>I'm afraid that the current plugin is still a bit too complicated for most users - and so they prolly lose interest (and self-confidence ;)) pretty fast.<BR/><BR/>The reason why I haven't done much fluid images/animations in the past is that it really takes a long time to render a high quality fluid. I don't know how/if this could be improved, but it would be something that'd make your plugin certainly much more attractive - especially to new users!<BR/><BR/>Also, the "mesh collision detection" feature is what I'm waiting for. Don't know if that's the correct term for it - I mean that you do not need to convert obstructive objects to subdivided TriMeshes anymore. I remember that this was planned some time ago. :) And again, this makes things a lot easier und thus more attractive for new users.<BR/><BR/>Of course, the "objects made of water" mentioned above, would be very nice, too!<BR/><BR/>In conclusion: Please don't abandon physics! They're worth it. :)<BR/><BR/>Greetings,<BR/>TroYAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-15340997.post-64343043913955205582008-05-12T14:22:00.000Z2008-05-12T14:22:00.000Z>>Please by all means, apply pressure.Hydrodynamic...>>Please by all means, apply pressure.<BR/><BR/>Hydrodynamic pressure if you want that! :)<BR/><BR/>I like playing with the simulation tool - though I must admit I had a quad core PC that I gave back after 14 days, and since then I´m back on my old athlon. This is only half the fun. I do hope that it pays to get a core duo or quad - doesn´t matter if AMD or Intel - in terms of fluids - for pure rendering the quadcore is/was fun with AoI.<BR/><BR/>So I do hope to see a "summer of code" by you - with features like multicore support and maybe those "objects made of water" which is nice - because you don´t need to fill those things up before.<BR/>(I loose often more water than I get in - which depends on the time step if I remember the manual right)<BR/><BR/>Greetings to vienna<BR/>HaraldAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-15340997.post-49333362184574954552008-05-03T09:30:00.000Z2008-05-03T09:30:00.000ZUnfortunately not.

Also quite a few folks have had quite serious bug issues. <BR/><BR/>Everyone said they are better off than with CVS and its distributed so thats good. <BR/><BR/>But the level of support and devlopment that git has received has made it a hard tool to beat.

I found Darcs then (not sure if git existed then) and haven't looked back (except with a smug grin). I read about git with interest about 2 years ago, and figured that it was probably meant for larger projects than AOI plugins.<BR/><BR/>Sounds like I should look at git in a bit more detail...<BR/><BR/>Hopefully we'll see some new code coming out of your git repository in the nearish future :o)<BR/><BR/>Cheers!<BR/>NikAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-15340997.post-9440112211649364512008-03-29T14:21:00.000Z2008-03-29T14:21:00.000ZGood to see you back in buisness deltor!HaraldGood to see you back in buisness deltor!<BR/><BR/>HaraldAnonymousnoreply@blogger.com
