3d scanner next image
Tomas
My idea is to take photos of bones (scapula, femur...) from different angles, run them through a software which will somehow combine them and make a 3D object in space, that i can rotate and add annotation (tags?, description for different parts of bone)
I am not a programmer and i need something easy.
Do you have any ideas? :)
Answer
photos are 2d. you can get depth, but not 3d. you need a 3d scanner like a next engine 3d scanner they run $3000. the web site is pretty cool, it will show you how to scan and print. the printer in the web site is is a year old and now they have much better printers with more options on materials available.
for software you will need a program like Solidworks. it is #1 right now for 3d. it is what Pixiar animation use and many large companies. there are other programs, but after my research for myself most will not talk to the scanner. down side is cost and you need a pretty big system to run it.
then if you want you can send it to a 3d printer for a few dollars you will get a actual 3d sculpture. there are several 3d printers, but after looking at many the 'shapesways gallery' they can print in plastics, metal, ceramics.
this stuff is super cool. this should lead you in the right direction. these printers have only been available for public about a year, but they have been around since the 80s.

What can I use to cast a mold from stone without hurting the stone?
disciple
I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!
Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.
Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)
