Digital Drawing Board Creates Objects in Stunning 3D Detail

http://gajitz.com/digital-drawing-board-creates-objects-in-stunning-3d-detail/ ETOS, or Electronical Tool for Object Sketching , is a tool for designers and architects that lets them see their creations in three dimensions without the need for 3D glasses.
A knot diagram of the trefoil knot In topology , knot theory is the study of mathematical knots . While inspired by knots which appear in daily life in shoelaces and rope, a mathematician's knot differs in that the ends are joined together so that it cannot be undone. In precise mathematical language, a knot is an embedding of a circle in 3-dimensional Euclidean space , R 3 . Two mathematical knots are equivalent if one can be transformed into the other via a deformation of R 3 upon itself (known as an ambient isotopy ); these transformations correspond to manipulations of a knotted string that do not involve cutting the string or passing the string through itself. Knots can be described in various ways.
