philnolan3d Posted September 16, 2009 Report Share Posted September 16, 2009 I don't know anything about trucks or their tires, but I thought it might be fun to make one in 3DC. So I looked around and found some that look cool. These are Dick Cepek Crusher tires. So far I have one strip of tread and need to array it around with either Wrap or Axial.

Contributor Tony Nemo Posted September 16, 2009 Contributor Report Share Posted September 16, 2009 You nailed the detail. Now it's counting skulls? Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 You mean the number of skulls to go around? I just counted, 21. Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 Rut roh... Slight problem, duplicating this with axial 21 times creates 110 million triangles. Normally my computer starts to choke at around 25 mil. Quote Link to comment Share on other sites More sharing options...

Normally my computer starts to choke at around 25 mil. Yeah, I ran into that issue too. With axial symmetry or the warp-tool one can easily create files which can not get exported by any means (at least on my Laptop). Saving raw mesh doesn't work and also Quadrangulation runs out of memory. Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 Yeah I'm working on trying to reduce the number of tri's on the one strip. It was I think 6.8 mil for the one strip, I've got it down to 5.3 now. Quote Link to comment Share on other sites More sharing options...
Advanced Member JamesE Posted September 16, 2009 Advanced Member Report Share Posted September 16, 2009 Haha, that's crazy! I hope you work this out though. Looking forward to seeing it put to use. Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 I actually got the idea after seeing this guy's tires. He used polygons though. http://forums.cgsociety.org/showthread.php...age=1&pp=15 Quote Link to comment Share on other sites More sharing options...

Phil, maybe it would be possible by making the tyre as a raw shape and then use "tools" with axial to remove one set of cavities after the other.

philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 I don't know how well that would work. Some of the details are pretty intricate. Quote Link to comment Share on other sites More sharing options...

Agree, this might be a problem. Also your voxel count will further increase the moment you make the tyre complete. But in any case it looks great.

philnolan3d Posted September 16, 2009 Author Report Share Posted September 16, 2009 I'm thinking maybe I can do an array of 3, then gradually duplicate and rotate it 7 times, making 21, and maybe it will be easier to gradually work my way into it. It might not turn out as precise, but it should be good enough. Quote Link to comment Share on other sites More sharing options...

It might not turn out as precise, but it should be good enough. For the profile pieces you have now this could work, but what will happen when you ad the baseshape of the tyre to them? Will you get the full voxel count which should be 120 to 130 mil? I hope you are succsessful. Quote Link to comment Share on other sites More sharing options...
Member MozzUK Posted September 17, 2009 Member Report Share Posted September 17, 2009 What about re-topoing the one section, baking a displacement map (or a normal map for that matter) and then using that all the way round? Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted September 17, 2009 Author Report Share Posted September 17, 2009 Well part of the point was to challenge myself. Maybe that could be done as a last resort, but it kinda feels like cheating. Quote Link to comment Share on other sites More sharing options...
Advanced Member Ratchet Posted September 17, 2009 Advanced Member Report Share Posted September 17, 2009 What about re-topoing the one section, baking a displacement map (or a normal map for that matter) and then using that all the way round Yeah , very good idea. Make the tire without the detailled section; make one section to bake it on the tire. Or use less detailled sections ? for more simple tires. Depends on your goal : presentation or game. For game players won't take too much attention to tires ,specially when the car is running ! Quote Link to comment Share on other sites More sharing options...
