🖋️ Line Art, Inking & Linear Rendering Taxonomy

A working glossary of 864 line-art and inking terms across 23 categories, plus a live style demonstrator — pick a term and watch it render on an actual figure instead of just reading a definition. Many of these terms overlap; a single illustration might combine a variable-weight brush contour, open light-side edges, feathered shadow transitions, spotted blacks, and engraved texture. A useful description formula: drawing mode + contour system + line quality + weight system + tonal method + black treatment + medium + stylistic tradition + production finish.

About this page

This taxonomy covers everything from basic drawing modes through line weight, hatching, medium, and entire stylistic traditions (comics, manga, technical drafting, children's books). Every term gets a full definition. Use the search box inside any glossary section to filter across all 864 entries at once, or jump straight to a category from the sidebar.

About the 👁 icons. ~190 terms — the ones that describe a genuinely vector-representable rule (line weight, contour behaviour, hatching pattern, black treatment, highlight system) — carry a 👁 button next to their name. Click it to jump to the live demonstrator and see that treatment rendered on an actual figure, live, with no image generation involved. Near-duplicate terms that would render identically (e.g. "Monoline", "Uniform line" and "Mechanical monoline") share one swatch — the glossary still lists all three, but the preview shows the one shared result.
Terms without a 👁 icon are text-only, deliberately. Most of this taxonomy describes things a flat vector demo genuinely can't show honestly — physical medium grain (charcoal dust, drybrush texture, risograph misregistration), print-process artifacts, or entire cultural/historical style families (Art Nouveau, ligne claire, gekiga). Faking those with a generic filter would misrepresent them. This page has no image-generation backend and no build step, so visual coverage is intentionally limited to what clean SVG code can faithfully render — read the definition for everything else.

1. Fundamental Drawing Modes

Contour drawing — describes the visible boundaries of forms.

Outer-contour drawing — emphasizes the exterior silhouette.
Interior-contour drawing — includes folds, anatomy, facial features, seams, and surface divisions.
Blind contour — drawn while looking primarily or entirely at the subject rather than the page.
Modified contour — slow observational contour drawing with occasional checks of the page.
Continuous-line drawing — the tool remains on the surface for most or all of the image.
Single-line drawing — an entire subject or composition is formed from one uninterrupted stroke.
Economy-of-line drawing — uses the fewest marks necessary to communicate the subject.
Gesture drawing — fast, energetic marks describing movement, rhythm, balance, and weight.

23. Compact classification template

A line-art style can be classified by answering these eight questions. Use it to describe a style you're looking at, or to write a precise AI-image prompt instead of reaching for a vague style name.

QuestionAnswer options
What defines the form?Full contour, selective contour, silhouette, implied edge, mass, or lineless value.
What is the line weight doing?Uniform, tapered, calligraphic, depth-weighted, light-weighted, or mechanically standardized.
What is the stroke character?Clean, smooth, rough, dry, scratchy, wobbly, gestural, geometric, or decorative.
How is tone created?Hatching, crosshatching, feathering, stippling, texture, mechanical tone, wash, or solid black.
How are light and shadow divided?Heavy shadow-side contour, open light-side contour, full black masses, white-line highlights, or continuous tonal rendering.
How is depth communicated?Overlap, line-weight hierarchy, atmospheric thinning, perspective, contour density, or color coding.
What medium controls the mark?Brush, nib, technical pen, pencil, marker, scratchboard, printmaking process, raster brush, vector, or generated contour.
What production system shapes it?Comics, animation, publishing, poster printing, technical drafting, scientific plate work, screen production, or digital display.
