Fig. 5From: Towards additive manufacturing oriented geometric modeling using implicit functionsThe shapes of these areas are defined by the C2-smooth implicit function \(B_{\Delta,\delta }^{(3)}(x,y)\) corresponding to the level value of less than 0.5. The underlying control polygon for constructing \(B_{\Delta,\delta }^{(3)}(x,y)\) is specified using the same set of vertices P0,P1,⋯,P8. All these shapes differ only by the δ values, which are δ=0.05,δ=0.15,δ=0.25,⋯,δ=0.55, respectivelyBack to article page
