On net I found this text
Description: We are currently in the market for several 3D artists who can creatte solid watertight models of characters (fantasy and sci-fi). These are to be very high res, using as much detail as possible with absolutely no textures. The final files should be saved in .stl or .slc format and still retain a smooth, life-like appearance.
The link of this page is here
I don’t know what these formats are?
can any one please tell me.
