Re: A Challenge
After several tries ending up in spectacular failure I think the best thing to do until an answer surfaces is scan a CD, I did and it looks rather real. Yet I will most likely try, try, and try again until I pass out on my keyboard, then wake up for school tomorrow with imprints of keys in my face, again...
Here was my only success. http://img406.imageshack.us/img406/7452/cd6iv.jpg A simple 12 faced model using a scanned image of an AOL CD and a OCA map. If anyone is wondering "How did you try so many times if he just posted this!?" I was talking to him before today. Got a little bit of a head start, but do not worry I don't plan to win this. Another picture. Here is a second picture. http://img486.imageshack.us/img486/5536/cd28ya.jpg Last edited by Morgan Gillespie : 21-05-2006 at 18:26. |

Re: A Challenge
Here's an idea to try (I don't have 3ds max installed on this machine nor the time lol, but maybe it'll give you something to work with):
Make a spline that is just very jagged and very thin and long. Then revolve that the 360 degrees. If you think about how a cd works, that's why you have those "rainbows". You can make this revolution a glass-like texture and if you use a renderer that will take into fact the way light splits through a prism (which is why the jagged edges will give you a rainbow) it should naturally create the effect you want and will react like a real cd would (since in practicallity your making one, including the surface texture). Good luck. |

A Challenge Indeed
Let me tell you right now that this is really hard and/or tricky.
I had this discussion before, with a guy named Andy Rak. We eventually came up with something that links the camera's axis with the CD material's coordinates, resulting in some spinning colors when the CD was turned a certain way. It was mostly gradient ramps. You can find it here: http://www.turbosquid.com/FullPrevie....cfm/ID/244497 I know that finalRender, as part of its finalShaders package, has a specific shader for this: http://www.finalrender.com/products/...PID=45&FID=390 Now, the tricky part is that I found one for sale that claimed to do it without any special renderers and stuff, just with normal max stuff. It looks pretty legit - maybe if we pool $39 we can find out. http://www.turbosquid.com/FullPrevie....cfm/ID/237227 |
