Hi, Could anyone tell me the degrees of 'Bspline' and 'Spline' on Gmsh?
I just learned how to approximate a circle with Bezier curves: http://www.tinaja.com/glib/ellipse4.pdf Could we do the same thing with 'Bspline' on Gmsh? (Yes, I'm aware of 'Circle' and 'Ellipse' on Gmsh.) Apparently, the following 'Bspline' does not look like a circle... //----- Point ( 5) = { 0.0000, 1.0000, 0.0000}; Point ( 6) = { 0.0000, 0.0000, 0.0000}; Point ( 7) = { 1.0000, 0.0000, 0.0000}; Point ( 8) = { 0.0000, 1.0000, 0.0000}; Point ( 9) = { 0.5518, 1.0000, 0.0000}; Point (10) = { 1.0000, 0.5518, 0.0000}; Point (11) = { 1.0000, 0.0000, 0.0000}; Circle (102) = {5,6,7}; Ellipse (103) = {5,6,7,7}; BSpline (104) = {8,9,10,11}; Physical Line (202) = {102}; Physical Line (203) = {103}; Physical Line (204) = {104}; //----- Regards, Shin
