  1. Looking for some help to get up to speed on how to write in the HDK properly and efficiently.
  2. High Resolution Explosion

    Wow this is a really cool thread. I'm looking forward to combing through this.
  3. Hey guys, Any quick pointers on how to access dop data from HDK. I'm trying to track down switchvalue data in a dop sim and add it to field data. with a custom gas microsolver.
  4. Realistic Dynamic Fracturing with Bullet

    Wow. Excellent work everyone. Thanks for sharing!

  6. Seriously thanks so much guys

    For those don't know bit coin is an amazing way to send payments around the globe. The transaction fee is next to zero and the transaction happens in seconds. Google for your favorite exchanges! Looking forward to the next bulletSOP dude! -Andrew

    I would do this with bullet and spring constraints. Then have a soft RBD transformer so the edges stick together.
  9. BulletSOP 2.0.11

    Hey Milan, Are you interested in accepting bitcoin as payment? You could have an address under your posts to take donations for people who relaly like the plugin. Super easy to send money around the world and no transaction fees.
  10. Activate the pieces in sops. They should only apear for a frame. Then use a RBD fractured object createing objects on every frame. Fell me?
  11. gas explosion

    I have been working on this for 3 weeks and have some pretty solid break through's. I'm definitely looking forward to contributing to this. One of the major ones to break up smooth bubble effects cause by high divergence is to use the laplacian of a the normalized heat field as a control field for turbulence. This allows you to put turbulence on the boarder of the heat. Dive into that turbulence node and multiply the out vector of the noise by a clamped dot product. Basically eliminating the downward values into the turbulence. Will post an example file soon as I can. Another one that is super handy. Advecting an additional field and dissapting it off quickly and using it for a control field in some violent turbulence. Diffusion and dissipation are key. Diving into a Gas vortex boost and adding a noise field to the radius of the blur nodes.This provided an interesting non uniform break up. I think its a heavy hit to ram though. I'm trying to edit a turbulence node to have a noise turbulence driving the size of my frequency so I can have a non uniform turbulence size throughout my fields. I hate seeing turbulence patterns. Drives me nuts. 2 substeps min. Its a pretty big hit, but it improves the quality of my sim's immensely For a explosive blast I use particle emission. I was think about some of the things mentioned in this post earlier today. I'm going to try using a high velocity particle emitter with this slow burn technique. I'm also considering boosting up the combustion otl to drive various parameters with fields. Ignition temperature could be controled by a custom field, as well as smoke emission. So. Many. Possibilities. Freaking endless. Speaking of particle emission, I came across a handy tip that puts meta balls on them, uses a gas field vop meta vop node to look it up. Super clever, havnt tried it yet though. But it seems like it would be quite a bit faster for particle emission. Houdini is absolutely amazing the control it gives you.I really wish I could share my current work! Old school, I always appreciate your thorough and informative posts. I'm really interested in the advected particles to transfer attributes over into various fields. So much potential here. Much Simulate. Very Fire. EDIT: Here is an example of the bubble field I'm working on. I had a sop solver version that had way more features but stumbled across a bug where the field would return a solid 1 in every voxel. https://dl.dropboxusercontent.com/u/3403330/BubbleField%20Example.mp4
  12. Blows me away that houdini doesn't ship with a bary bind.
  13. FLIP smorganic/sheeter effect?

    Very cool stuff
  14. BulletSOP 2.0.9

    Hey Milan, Here is an exmaple scene of where pin constraints would come in really handy. Maybe I'm doing something wrong. But my clustered pieces are acting way to stiff. I also have the stiffness set to zero. https://www.dropbox.com/s/4n15vta410jrhc7/01_Nuke_v73_Example.hipnc Again, Great work, -Andrew

    Wow this thing is absolutley amazing. I am blown away. A couple things. It would be nice if there were more constraint types. H13 has a pretty slick workflow. It seems like you have a super constraint? It would be ncie to have types. Like Spring, Glue, and Pin, with controls to restrict movement so we can get a hinge. But maybe you have this already. Regardless I can't wait to get my stuff up on vimeo. Super awesome plugin you have here. Are we able to plug in friction attributes? This is so fast man. Holy crap. So fast. So freaking fast. Ill have more feedback for you. And a donation! Pretty amazing man.
