Here you go... check the attachment. If you want the "z" value moving on the sprites... just go into the composition, and attach the "z output" that goes to the z input of the cube, to the z input of the sprite. (BTW, the mouse patch can be setup to do the same as a trackball with some javascript when connected to a 3D transform- and can even be rigged with math expressions if you aren't interested in the "inertia" functions, not getting more into that since your note is about the sprites always facing the viewer.)
Depending on where you are going with this, you may want to experiment with the various "blend" modes on the sprite patch, and see what is most favorable for your purpose. -George Toledo On Fri, Jan 23, 2009 at 2:22 PM, aienn <[email protected]> wrote: > hey listers, > I'm trying to recreate a simple (yet nice) PC screensaver in QC > structurally it's very much like a bundled example > have a look: > /Developer/Examples/Quartz Composer/Compositions/Conceptual/Noise - 3D.qtz > > there are proper 3D cubes in that example grid > but I need to have 2D sprites in their place that always face the user > and I'm not exactly sure what sort of renderer patch of use in place of > those cubes > and how to position them so they'll always face the user > > any ideas? > > a. > _______________________________________________ > Do not post admin requests to the list.
