I wonder how long it took Braben and Bell to iterate the design of the Elite radar back in 84, to display objects in 3D space?
Says the guy wrangling with FOV for a 3D space in a 2D game.
Does the attached screen top-right make intuitive sense to you? No, didn't think so.
Hint: heading is shown on the left and is 90 degrees. The coloured boxes in the targeting console are for the current plane/depth, cell density/colour indicates distance to solid rock.
