Common Options

-R

Region. In 1-D this is xmin/xmax. In 2-D this is xmin/xmax/ymin/ymax. In 3-D this is xmin/xmax/ymin/ymax/zmin/zmax.

-I

Grid increment. Optional dimensions inherit from the first increment. In 1-D, this is dx. In 2-D, this is dx/dy. In 3-D, this is dx/dy/dz.

-F

Window taper functions for each dimension. Run blend --show-windows to list available names. In 1-D, this is xfunction. In 2-D, this is xfunction/yfunction. In 3-D, this is xfunction/yfunction/zfunction.

-T

Taper ratios for beginning and ending sides of each dimension. In 1-D, this is rx1/rx2. In 2-D, this is rx1/rx2/ry1/ry2. In 3-D, this is rx1/rx2/ry1/ry2/rz1/rz2.

-B

Blendfile input for multiple polygons/supports.

-C

Clobber mode for polygon overlap handling: first f, lowest l, last o, highest u, arithmetic average a, geometric average g, or product p.

-M

Monotone conversion method for non-xy-monotone polygons. Options include e, b, E, and B. Options e and b are only available for the monotone module and use the regular mathematical definition of xy-monotonicity, for nondecreasing vertices. Options E and B are the only available options for the window2d and window3d modules and use a stricter definition of xy-monotonicity, for strictly increasing vertices.

-N

Write polygons modified by -M by inserting _monotone before the file extension, for example south_america_monotone.txt for south_america.txt.

-V

Verbosity. Levels are quiet q, errors only e, warnings and errors w, timings, warnings, and errors t, informational messages, timings, warnings, and errors i, compatibility messages and all lower verbosity messages c, and debug messages and all lower verbosity messages d.
