Surface triangulation

Triangulation of a surface meansTriangulation: cylinder, surface x 4 + y 4 + z 4 = 1 {displaystyle x^{4}+y^{4}+z^{4}=1} Triangulation: cylinder, surface x 4 + y 4 + z 4 = 1 {displaystyle x^{4}+y^{4}+z^{4}=1} , POV-Ray imageTorus: triangulated by the marching methodTorus: polygonized by the cutting cube method Triangulation of a surface means
