anoop Posted September 7, 2010 Share Posted September 7, 2010 Hi, I am a newbie to Houdini and new to this forum.. How can I fracture objects or a grid using a image?...for doing RBD simulation.. http://i278.photobucket.com/albums/kk111/Hello4114_2008/GlassShatter.png regards Anoop Quote Link to comment Share on other sites More sharing options...
TheUsualAlex Posted September 8, 2010 Share Posted September 8, 2010 Hi, you might be able to use Trace SOP for something like that depending on your situation. Trace SOP can still create a "gap" between those edges that may not be desirable if it's close up... Quote Link to comment Share on other sites More sharing options...
fxrod Posted September 8, 2010 Share Posted September 8, 2010 Actually, I use those gaps to my advantage for things like concrete, asphalt, etc. Whenever objects in the real world are fractured, you lose material at the fissure. If you use the trace SOP, make sure you then fracture the "grout" material. These smaller pieces can add some nice detail. Quote Link to comment Share on other sites More sharing options...
CeeGee Posted September 8, 2010 Share Posted September 8, 2010 You can also try this setup using TraceSOP Scene file from Montreal Houdini user group http://www.trinix.ca/mhug/tutorials/2008_09_18_blastcode_shatter.zip Quote Link to comment Share on other sites More sharing options...

chippey Posted September 10, 2010 Share Posted September 10, 2010 I'm kinda a houdini newbie, but I'm curious about this and playing with ideas along this line too. Is it possible to fracture already existing geometry based on an image? I've got an .obj with its own set of UV's mapped, and a painted set of cracks on that UV set. I found the trace SOP, but it only seems to want to generate new geometry on a plane. Is there a way to fracture my existing obj based on an imaged mapped to its UV set? Cheers!
