Classic Mercator Procedural Live Wallpaper
Antique maritime world chart showing accurate continental coastlines, nautical rhumb lines, and the solar day-night terminator. Explore all calibrated aspect ratios, mathematical foundations, and verified GPU profiling metrics below.

Calibrated Aspect Ratios
Select your display setup for aspect-calibrated bounding boxes and camera projections:
Standard Widescreen (16:9)
Center-weighted radial projection, 16:9 bounding box, standard camera frustum optimized for horizontal workstation and desktop displays.
Ultrawide Desktop (21:9)
Extended horizontal FOV (Field of View), panoramic particle distribution, and expanded lateral viewport clipping planes.
Super Ultrawide Dual-Monitor (32:9)
Double-frustum projection matrix, dual focal symmetry centers, and continuous lateral flow preventing seam distortion across dual-display spans.
Vertical Portrait & Mobile (9:16)
Vertical aspect layout with top-to-bottom gravity/flow vectors, column-oriented particle density, and tall perspective projection.
Mathematical Foundation & Algorithm Breakdown
Maps spherical Earth coordinates $(lat, lon)$ to planar coordinates using the conformal Mercator projection $y = \ln(\tan(\pi/4 + \phi/2))$. Solar sub-stellar coordinates compute the sinusoidal day-night terminator curve.
