GRIDREVOLVE Revolve and extrude a 2D grid.
[ GRID ] = GRIDREVOLVE( GRID, N_CR, LZ, N_REV, R_OFF, TH_XZ, I_JOIN ) Revolves and extrudes a 2D GRID to generate a 3D grid. N_CR is the number of cell rows in the revolved direction, and LZ the length/offset height in the zdirection. N_REV specifies the number of revolutions, and R_OFF the radial offset of the original input grid. TH_XZ optionally prescribes an initial angle of the input grid plane (default pi/2). (I_JOIN is optionally a flag to enforce joining the two ends, default I_JOIN = LZ==0 & N_REV==1).
grid = gridrevolve( circgrid(), 20, 0, 1, 2 );
grid = gridrevolve( rectgrid(3), 100, 10, 3, 2 );
grid = circgrid(); grid = delcells( grid, 'x>=0' ); grid = gridrevolve( grid, 20, 0, 1, 1 );
