and for all the levels belowit. When for a volume the attribute FILL is > 1 (and the option SHAD is on), the ABS of its colour code must be < 8 because an automatic shading of its faces will be performed. ’FILL’ (1992) fill area -7,...,0,1,...7 (default=0) when option SHAD is ’on’ the FILL attribute of any volume can be set different from 0 (normal drawing); if it is set to 1, the faces of such volume will be filled with solid colours; if ABS(FILL) is > 1, then a light source is placed along the observer line, and the faces of such volumes will be painted by colours whose luminosity will depend on the amount of light reflected; if ABS(FILL) = 1, then it is possible to use all the 166 colours of the colour table, becouse the automatic shading is not performed; for increasing values of FILL the drawing will be performed with higher and higher resolution improving the quality (the number of scan lines used to fill the faces increases with FILL); it is possible to set different values of FILL for different volumes, in order to optimize at the same time the performance and the quality of the picture; FILL0 and
