Isovalue—

Marching Squares walks each cell of a scalar grid, classifies its 4 corners against an isovalue into a 4-bit index, then looks up the line segments. Endpoints are linearly interpolated along edges where the field crosses the isolevel — giving smooth contours. Drag the metaballs; in Paint mode draw on the canvas to sculpt the field.
