rdg Posted April 25, 2007 Share Posted April 25, 2007 Hi, here is another puzzle part for my current WIP 'RDG Pandora' [1][2]. The aim of this work is to investigate the interplay of dynamics and other stuff I learned the last months. The is part is called RDG Snake Eyes. This setup ensures that dropping cubes stop their motion facing the 'right' side up. I fetch the orientation of the boxes using a dynamicsCHOP. The channels are reversed and then converted into constants. That way I can pre-re-rotate the boxes in SOPs and apply the motion using a dynamictransform. Number of cubes sets the number of cubes to be dropped. To vary their motion their Z velocity can be changed. Pressing the button 'update simulation' caused the chops to be updated or snapped. And voila - snake eyes again. Well almost every time.

rdg Posted May 3, 2007 Author Share Posted May 3, 2007 (edited) I tried to replace the boxes with my folding cube. But there were some problemes as I merged the rig into my simulation and I got strange offsets. I guess this can be explained with different coordinate systems. To get closer to the solution I simplified the setup again: http://proforma.preset.de/tai-chi-hou-dini/pandora/20070503/ mp4 only: http://proforma.preset.de/tai-chi-hou-dini...0070503/p_7.mp4 The boxes open now smoothly. The current question is: How do I create/rename channels on-demand to match my cube number to offset/strech the opening times of the boxes.

rdg Posted June 20, 2007 Author Share Posted June 20, 2007 a new approach to color releasing: flipbook: http://proforma.preset.de/tai-chi-hou-dini/rdg-rc_01.mp4 and a whole bunch of new particle questions. to be solved in the future.

rdg Posted June 21, 2007 Author Share Posted June 21, 2007 (edited) thank you, jason. Now I tried to stamp the colors to the floor. The more hits/collisions the more intensive the color. The concept gets illustrated - but still a long way ahead: Flipbook: http://proforma.preset.de/tai-chi-hou-dini/rdg-rc_02.mp4 Is it possible to access the $JUSTHIT in a VOP POP - probably. I remember a thread where somebody explained howto access attributes form previous frames in pops. Edited June 21, 2007 by rdg Quote Link to comment Share on other sites More sharing options...
rdg Posted June 25, 2007 Author Share Posted June 25, 2007 some cubes don't need colors: Animation: http://proforma.preset.de/tai-chi-hou-dini...-cg_03_0001.mp4 Some unstructured comments: http://forums.odforce.net/index.php?showto...amp;#entry37066 Quote Link to comment Share on other sites More sharing options...
rdg Posted June 25, 2007 Author Share Posted June 25, 2007 but some colors help to see things that don't happen: Flipbook: http://proforma.preset.de/tai-chi-hou-dini...-cg_04_0001.mp4 Quote Link to comment Share on other sites More sharing options...
