A computer program for visualization of three dimensional surfaces is described. The surface is generated from a set of two dimensional slices of a three dimensional object. A three dimensional binary object is generated by selecting a suitable gray level window. The cubic voxel approach has been used for description of the object. The boundary surface is tracked from the user specified starting point. The options for specification of spin and tilt angles lead to visualization of the other side of the object. Surface shading is carried out based on the direction of the surface normals. The two dimensional gray level image is then displayed on the computer terminal.
