Command line

complexplorer render <func> [options]   # a 2D or 3D image
complexplorer stl    <func> [options]   # a 3D-printable STL
complexplorer list   [--tag TAG]        # browse the preset catalog
complexplorer gallery [options]         # a reproducible asset bundle

Every command takes a function the same way: either preset:<id> from the catalog, or an expression string such as 'z/(z**10-1)', which is evaluated safely — it is parsed, not evaled.

render

complexplorer render preset:pole_flower_10 -o flower.png
complexplorer render "z / (z**10 - 1)" --domain annulus:0.2:3 -o flower.png
complexplorer render "z**3 - z" --mode riemann --scaling arctan -o relief.png
complexplorer render preset:square --mode 3d --show

Option	Meaning
--mode {2d,3d,riemann}	flat portrait, analytic landscape, or Riemann sphere
--domain	rect:RE:IM, disk:R or annulus:IN:OUT
--cmap	phase, or phase:6 for six sectors
--scaling	modulus scaling for 3d and riemann, e.g. arctan
--resolution	samples per axis
--output, -o	write to a file
--show	open an interactive window instead

stl

complexplorer stl preset:pole_flower_10 --size-mm 80 --resolution 200 -o flower.stl

--size-mm is the printed size of the longest axis, --scaling defaults to arctan, and the mesh is repaired and checked for printability before it is written. See the physical workflow for what those checks mean.

list

complexplorer list
complexplorer list --tag singularity-detective

Prints the catalog: seventeen presets, each with its id, title and tags. The tags are how the catalog is sliced — canonical, poles, branches, ornament, transcendental and others.

gallery

complexplorer gallery -o bundle/
complexplorer gallery --tag ornament -o ornaments/
complexplorer gallery --preset identity square sqrt -o three/

Renders a preset selection into a self-contained bundle: a portrait and a card.json per preset, plus a top-level index.json manifest. The manifest is byte-stable — identical for the same selection and library version, on any platform — which is what makes it usable as an interchange record rather than just a folder of images.

This is the library's own gallery generator. The documentation gallery on this site is produced by examples/showcase.py, which adds the curated tour on top of it.

A note on consoles

Output degrades rather than crashing on a console that cannot represent a character — a preset title such as z³ - z on a legacy Windows code page will show an escape rather than ending the command in a traceback.
