Affine view (left)
Slice view (right)
Left: standard affine algebraic mesh of V in the chosen chart, clipped
by Max radius. Right: V ∩ S_c traced by predictor-corrector continuation,
rendered as TubeGeometry. The slice's projection into the affine pane
is overlaid as bright LineSegments when the toggle is on. Drag canvases
to orbit; scroll to zoom; shift-drag to pan.
