help with rendering images

ok i know that PB can make games and all, that is take resource files, pictures, 3d graphics and render it on a screen to make a world. now, in my PHD research, we cut sections of tissue 1/1000 of a millimeter thick. what i want to be able to do is take a picture of those sections as a TIFF file, and then reassemble them into a digital model of the tissue. since PB could open the file, draw it on the screen, and give it an actual thickness, isnt it possible to take maybe 100-150 of them, open them, assign a thickness, and draw them all on the screen to render a "world" actually inside the tissue. then youd be able to "walk" around that world like a game character would like in "restriced area". isnt that game just a bunch of image and graphic files all drawn together to make a world. cant you do the same thing with my tissue sections? any ideas?

a 3d world consists of connecting polygons that make up an object that has volume. 2d Images do not have volume as they are 2d (height + width). You should look into using voxels, that is volumetric pixels, that is used in the medical field for what you describe. Also Directx 9 supports Volume Textures, something you might want to look into.

anyway, those images *have* depth, as every slice has a certain thickness, one could create objects with a height parameter, size the same as slice thickness, vertical location depending on slice number
