Isometric 3D in 640x200 resolution, 4-color mode, from Tandy 1000 graphics in GW-BASIC. Running on the PC-BASIC emulator. It uses the PAINT (fill) command, via averaging the 4 points of the polygon, which is not necessarily flat, so this can break (and then paint the entire screen). Also, since PAINT needs a border color, you cannot use the same colors as the final line drawings. Therefore, you must draw the lines a different color, then PAINT fill, then redraw the lines.
