Similar shapes Squircle



a squircle (blue) compared rounded square (red). (larger image)


a shape similar squircle, called rounded square, may generated separating 4 quarters of circle , connecting loose ends straight lines. such shape similar not identical squircle. although constructing rounded square may conceptually , physically simpler, squircle has simpler equation , can generalised more easily. 1 consequence of squircle , other superellipses can scaled or down quite easily. useful where, example, 1 wishes create nested squircles.



various forms of truncated circle


another similar shape truncated circle, boundary of intersection of regions enclosed square , concentric circle diameter both greater length of side of square , less length of diagonal of square (so each figure has interior points not in interior of other). such shapes lack tangent continuity possessed both superellipses , rounded squares.
