Animated topographic contour map: a slowly-morphing terrain height field rendered as crisp anti-aliased isolines with heavier index contours every Nth line, hypsometric tint bands between index levels, soft hillshade relief, and paper-fibre texture. Moving the cursor raises a smooth hill under the pointer and concentric contour rings bloom outward around it. Swiss cartography meets a Field Notes notebook.
Elevation tint ramp from lowlands to peaks (2-5 hexes). Keep the first color close to the bg paper so plains stay clean; later colors set the highland mood — warm tans/terracottas for vintage maps, deep greens for phosphor terminals, navy steps for nautical charts.
Contour line ink: first hex = regular lines, optional second = heavier index lines. One color auto-derives the index ink (darker on light paper, lighter on dark). High contrast vs bg = bold drafting look; low contrast = faint ghost survey.
The paper color the whole map sits on. Warm cream = vintage field map, near-black green = phosphor radar, deep navy = blueprint chart.
Backdrop opacity. 1 = opaque map sheet; 0 = transparent ghost isolines floating over the host section (only ink lines and faint tint bands show).
How fast the terrain morphs. Higher = ridges visibly reshaping, restless; lower = near-still survey sheet that only drifts over minutes. Keep <= 0.5 for hero backgrounds.
Number of contour elevation intervals. Higher = many fine tightly-packed lines (dense engineering chart); lower = a few sweeping lines with lots of open paper.
Every Nth contour is drawn heavier and bounds a tint band, like real survey maps. 5 = classic cartography rhythm; 0 = uniform lines with per-line micro tint steps.
Extra thickness of index contours. Higher = bold confident map hierarchy; 0 = all lines equal hairlines.
Base stroke width of all contour lines. ~1 = crisp 1-1.5px pen lines; higher = marker-like bold strokes; lower = ultra-fine etching.
Strength of the hypsometric fill bands between index contours. Higher = clearly layered colored elevation zones; 0 = pure line work on plain paper.
Hillshade strength (light from the upper-left). Higher = embossed 3D terrain relief; 0 = perfectly flat printed sheet.
Terrain zoom. Higher = more, smaller landforms crowded into frame; lower = one vast continental sweep with broad calm areas.
Domain-warp meander of the contour shapes. Higher = wilder serpentine coastline-like wiggle; 0 = smoother, rounder blob contours.
Paper fibre mottle and grain. Higher = tactile notebook stock texture; 0 = clean digital flat fill.
Cursor terrain-raise strength. The pointer grows a smooth hill and contour rings bloom outward around it, with slightly darkened survey ink nearby; 0 = no interaction, pure ambient map.
