Figure 9From: Visual data mining based on differential topology: a surveyFirst list of singular fibers for stable functions V → R2for a 3D bounded domain V : those in this list appear along curves in the range [[15]]. Both the black dot and the black square represent a point: however, the former one is in the interior of V, while the latter one appears on the boundary of V. Void squares represent tangencies with the boundary ∂ V.Back to article page
