Particle Tools Demo: Explosions and Time Freezing

smokris's picture

A Quartz Composition using Kineme Particle Tools and the new Explosion force in v0.2. Time freezes occasionally whilst the camera rotates around the universe.

Rendered using QuartzCrystal 1.2 which includes a new temporal supersampling (motion blur) feature.

Render Settings:

  • Framerate: 24fps
  • Spatial Supersampling: 4.0x
  • Temporal Supersampling: 32x
  • Resolution: 720x480 (prior to Vimeo's transcoding)

I really like it. Good effects, and nicely presented.

With texturing and a bit of post-process, this plugin could be really awesome :D

i am so frustrated i can't play with 3d properly in the planetarium context (see elsewhere), as this is just the kind of thing i was aiming for. imagine it all exploding around you!

Why can't you?

Why can't you play with this in a planetarium properly? I am building a planetarium over the next 2 years (in a larger community center) and am researching all of this for dome projection. I'm curious to know what problems you are having.

Very Impressive!

I'm not sure about the orange flash bits, but the particle stuff itself looks loverly...

Thanks, everyone.

Textured particles are on our todo-list. Coming sometime in the future. As long as time doesn't freeze in the meantime. Though I guess if it did we would have no real way of detecting it...

The orange flashes can be disabled --- they're just the 'default visual manifestation' of the explode effect, and I turned them on for debugging purposes. They also remind me a little of some of Charles Csuri's early work and/or the Vectrex, so I left them turned on for sentimental reasons :^)

Strangely enough I think Cwright wrote this :D It might be of some interest, it deals with the PBMesh plugin on this site.

There's no real way to change the color of the flashes, is there? When I apply color change it isn't taking...

smokris's picture
No, there isn't.

You're right --- the Force: Explosion flashes aren't responding to the color parameter. I hadn't tested that parameter, actually. I've made a note to fix that for a future release.

yep, but you can't get a 180deg fisheye in qc...

this is the thread i referred to as (discussed elsewhere)

explosion render

I was having fun messing around with settings.... I rendered this last night. This has motion blur applied... without it, the variety of colors in the particles are very distinct. The blur definitely gives it a "wet" look... splish splash.

I have a question... what does the "quartz crystal render" checkbox actually do? I have to admit that every time I have checked it, if I am in Quartz Composer, or Quartz Crystal, I have had either program totally lock up.

locks etc

it'll lock because it renders an incomprehensible number of particles, and unless you've got a fast video card, lots of ram, and a fast CPU, you're toast (the 1 minute of video took about a day to render on a relatively new MacBook Pro -- particleTools is not fast by any means yet).

the check box is part of the presently undocumented automatic inputs QuartzCrystal populates when it renders. I'll document those a bit more clearly when release-time comes around, but the e-mail I fired off you you contains a fair basic summary.

Don't use "embed url"

The video insert html doesn't seem to work?

I edited your post and got it to work --- keep in mind that you should enter the standard video-page url (not the "embed url" or the "fullscreen url"). It's easier than you think.
