  1. dont use the builtin eyeball offset at all, use the materials transform property.
  2. ok, i have now compiled a v13 version for both, Zevel and puZh. i have also fixed a glitch that occurred with Zevel for some time now which positioned one cp wrongly for loop-splines. get the updated files at this url: http://www.kci-group.com/z/ please delete any old version of puZh/Zevel from your HXT folder, since i have changed the plugin names, so they will not overwrite!
  3. i have had a report of puZh not working with v13. i have just gotten v13 myself, so i'll very soon check out these troubles and hopefully fix them! thanks for your report!
  4. hmm .. i guess there must be different approaches to this. filling the field with particles would resolve many of the issues, but how will this simulate 2 differently colored fluids mixing with each other? would each particle have a color and that would "rub off" onto neighbouring particles? any time you have is greatly appreciated! i'll try to do much of the a:m related coding, but as i've said, i dont think i can code much of the actual simulation. for the models: i have successfully read transformed model data before, but still i'm not sure if thats enough ..
  5. hmm for some reason the markup wont work in this forum .. anyway - i'd like to use some open source software, because i doubt anyone here has the ressources to develop a comprehensive cfd implementation. and since there are a LOT of implementations out there, i was hoping someone would have stumbled accross something useful. you are right, most of the implementations i've found are geared towards engineering .. i've read a few papers about cfd, and some claim they get great looking results from a relatively coarse grid. others are using flexible grids (octtrees), but i'd be interested in some numbers. is a 100x100x100 grid a coarse grid for a bowl of water? i'm not sure if interpolation is feasible. for a particle based solution yes, but for a density bitmap i dont see how that would work out, unless the interpolation would use the navier stokes equation itself. if the simulation rund in realtime, it should be possible to solve every sub-frame .. unless the equations become instable for very little change .. anders, maybe we could team up on this project? as you'll see in the materials forum, i've already conducted some experiments with rendering volumetric data and i am quite pleased with the results so far. another problem is: how can we "feed" the solver with scene data from a:m? for the surface water plugin i did a while ago, it was relatively easy: i simply shot rays (perpendicular to the water surface) into the scene to detect any changes that would occur. a cfd solver would need the volumes of every a:m object intersecting with the simulation field plus the object motion vectors. but even only getting the volume data might be difficult, as there is no easy way to tell if a certain position lies inside an object or outside of it.
  6. anyone knows a good CFD software for win+mac? i'm searching for a good CFD solver. i'd like to create an interface between a:m and the solver, but as of yet i didnt have as much luck .. OpenFOAM looks very good, but they say its only feasible to be used on unix flavours. ideally the software should be a c++ library package to solve cfd problems, to avoid too much hassle for the a:m user. also: i currently have not much of an idea how those simulations work. how fast are the calculations? what grid sized will produce good results? how well do these simulations perform for sub-frame advances (multipass!)? anyone has wishes or ideas for the a:m integration? if someone can shed some light on these questions i'd be grateful, and maybe this brings us one step closer to cfd in a:m!
  7. it quit my internet explorer once yesterday too
  8. i like most of the changes, but the forum somehow lost my password .. i had to go through the "forgot password" process to set it again.
  9. this solution would upheld the anonymity rule, but i think it would defeat most of the purpose. but maybe this would work: the contest forum threads could be "anonymous" threads until the contest is closed. i'm not sure, if the forum software supports this feature or if it could be added, but it seems pretty straight forward to do: in the modules that handle - index.php?showtopic=XXX - index.php?act=Post the names, signatures, email buttons, avatars etc. of the posters should just not be shown, if the thread is set to "anonymous". if its too difficult to add a property to the thread, the description could be set to "anonymous" by the creator. when he wants to "un-anon" his threat, he can just edit that to say something else.
  10. i aggree, anonymity usually is a plus for contests. but when favourism comes into play, i think it doesnt help much that the name isnt added to the image, as someone could just send out some mails like "hey, go there and there and vote for my pic, its the 3rd row down, 2nd pic, the yellowish ball." of course i could be wrong about that, but as i have experienced this great hash community, i think (most) people are mature enough to be fair.
  11. some facts (afaik anyway) to start with: - hash contests sometimes have low participation - it is policy that contest entries are not to be shown before voting i think this could be improved by allowing WIP threads for the contests. -> responses from the community to the wip could keep the artists' interest alive and make them go the whole way. -> quality of the entries could even be improved since the artist would get early criticism for the project. -> contest deadlines could be prolonged if there are many active wips, but few final submissions.
  12. well, he's only got vampire TEETH (probably false teeth, but from a real vampire). i wouldnt go as far as saying that whole keekat is a vampire. and i think the picture clearly prooves that.
  13. hey! for all you people out there favouring The Dark Side over any christmas any time, here is a little seasonal treat: Vampire Vampire allows you to change the Diffuse Color and the Transparency of a material when seen in a mirror. Just set the Opacity, Color and Tint percentage you want to have in the mirror, drop the material on your vampire and you are done. http://www.kci-group.com/z/vampire.htm also check out keekat's new cool vampire teeth! Vampire is Freeware. have fun + post some pics using it here!
  14. will there be any statistics about the "preferred system" or hardware profile or is it just to improve support?
