Tom Posted July 1, 2008 Share Posted July 1, 2008 Hello- Does anyone know how to create a kaleidsocope image, through rendering (or otherwise) ? Something similar to the attached jpg? I was hoping there was some sort of AM render effect that might work, or something that would at least create part of a kaleidoscope section....... that could then be x flipped. I was looking at my After Effects filters and they have something which says it creates kaleidoscopes but is more a "Tiling" sort of thing that looks cheesy anyway. Thanks for any suggestions!

NancyGormezano Posted July 1, 2008 Share Posted July 1, 2008 Most likely Johnl3d will chime in here eventually - as he was doing something similar: http://www.hash.com/forums/index.php?s=&am...st&p=271412 essentially I believe - he placed objects inside a 100% ? reflective sphere/cube and set the number of reflection levels to some number of your choice (default =2) when rendering Quote Link to comment Share on other sites More sharing options...
Paul Forwood Posted July 1, 2008 Share Posted July 1, 2008 Try constructing a 100% reflective cylinder and then experiment with different arrangements of flat mirrors in the centre. Add some coloured particles and some rotation. Maybe try using Newton Physics with small coloured beads. You could also try fluids for a bit more fun. Just add a light to one end of the cylinder and a camera to the other. Oh. Post some results please. ------------- Edit: Better to use a flat sided cylinder rather than a round one. Edit: Hmmm. I just tried that and it didn't work. Quote Link to comment Share on other sites More sharing options...
Luuk Steitner Posted July 1, 2008 Share Posted July 1, 2008 This website shows how a real kaleidoscope is made: www.kaleidoscopesusa.com/makeAscope.htm It's pretty easy and you should be able to get similar results with CG mirrors. Quote Link to comment Share on other sites More sharing options...
johnl3d Posted July 2, 2008 Share Posted July 2, 2008 did a quick attempt with a animated material on a sphere with a triangular mirror tube stuck into it with a light inside the tube along with the camera with the view clipped by a model disc with a hole in it. kal.mov layout Quote Link to comment Share on other sites More sharing options...

Hoo Hoo - fabulous John! (but..ummm...huh? you stuck a whatsis in a whosis ?) Quote Link to comment Share on other sites More sharing options...
johnl3d Posted July 2, 2008 Share Posted July 2, 2008 see diagrams for a hint .. model tritube.zip this should be easy even for the artists to understand...like NG.... Quote Link to comment Share on other sites More sharing options...
Admin Rodney Posted July 2, 2008 Admin Share Posted July 2, 2008 I haven't had a chance to look at John's project so have no way of determining how different my approach may be. I suspect John's is closer to building a real kaleidoscope whereas this method is a straight out cheat. I would use patch images driven by a sequence of images to drive the kaleidoscope. Especially if you are just wanting to create the image you first posted. The image is basically just a repeat of the same image multiple times around a common origin. If you were to lathe a fairly simple cone from a 2 CP spline then either flatten that or set a camera up to view it correctly applying a image to the Group should work pretty well. (16 cross sections in your image... or is that 15?) Consider transparency Consider flipping Normals Consider Rotating individual patch images Consider multiple layers of sequential images applied to the same Group Edit: Attached is an example of the basic idea first image (left) is the basic image used second image (middle) shows the geometry used to create the results third image (right) shows the results Quote Link to comment Share on other sites More sharing options...
Tom Posted July 2, 2008 Author Share Posted July 2, 2008 Many thanks to all the contributors and John's animated Kaleidsocope was awesome!!!!! This was supposed to be for a book cover design and since there was a short deadline I wound up modeling and rendering one of the 16 "petals" and then I recreated a kaleidoscopic mask by hand in Photoshop for the printers. Thanks again...the forum is an amazing resource. Tom Quote Link to comment Share on other sites More sharing options...
Paul Forwood Posted July 3, 2008 Share Posted July 3, 2008 Nice example, John! I finally worked out the problems that I was having by turning off all the lights, and shadows, and setting the subject matter to 100% ambience. Not quite the effect that I was after but... it's not needed now anyway. Quote Link to comment Share on other sites More sharing options...
