The combination of BFC with blocking-off some cells to fit extra geometrical features, may bring the number of practical advantatges. In this case the sphere and cylinder will be "drilled-out" in the beam of asteroidal cross section. ENDDIS PLANTBEGIN real(twopi,littler) littler=1.0;twopi=2.0*3.14157 RG(1)=TWOPI ** Calculate BFC star-shaped gridXC=:LITTLER:*FLOAT(J-1)/FLOAT(NY)* COS(RG(1)$ *FLOAT(I-1)/FLOAT(NX))**3 YC=:LITTLER:*FLOAT(J-1)/FLOAT(NY)* SIN(RG(1)$ *FLOAT(I-1)/FLOAT(NX))**3 ZC=5*FLOAT(K-1)/FLOAT(NZ) ** Drill the sphere MARK=SPHERE(1.,0.,0.,4.0,0.6) ** Drill the cylinder MARK=XYCIRC(1.,0.,0.,0.3) REGION(,,,,9,20) The use of SPHERE, XYCIRC and other geometrical functions is similar to cartesian cases. The difference is that arguments must be specified in terms of reference cartesian coordinate system. The latter is of routine use for all BFC problems. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< PLANTEND ************************************************************ Group 1.
