OVERSCANUI KIT
no button at all a worn bezel with weight channels do not converge zero depth instrumented, full of smoke a field of real characters a camera looking out additive, so no shadow hairlines, no new shader no raster, so no scanlines

A range ring is not a circle. Pitch the camera and the ring on the ground becomes an ellipse on the glass. The screen circle a HUD would draw is sized to be right to the north, and the key prints where it really reaches north and east, measured by casting those points back onto the ground. The ground is laid out so that every distance FROM THE CENTRE is true, and the key says only those are. A stale track is dashed, says how old it is and draws no heading; a heading line is a real ten-minute lead at the reported speed; a track off the view or without a position is counted. Pitch stops at 45 degrees. Every track here is simulated.

What it refuses

Outlines asked for and never given; a source that never answers.
