Abstract: A computer system that creates a deal space graphical user interface which is particular to each negotiation and displays on a 2-dimensional graph the degree of satisfaction for each side for all possible deal structures is provided. The deal space system provided shows how to simultaneously alter agreement terms to increase overall satisfaction for each side, making it easy for a user to see win-win tradeoffs.

Abstract: An object rendering system having a specialized algorithm is provided to convert a material and geometric description of an object to an X-Ray image of that object for use in medical applications and industrial non-destructive testing, thus to permit presentation of an object not the result of X-Ray in an X-Ray format. The system operates by considering that the object is composed of nested geometric solids, each defined by an enclosing surface, with the material property of each nested solid being defined in terms of an X-Ray mass-attenuation coefficient. Means for adjusting the mass attenuation coefficient of each of the enclosing surfaces is provided to permit each solid to be rendered independently.
