Now I’m doing my master thesis in Siemens using C++ and python. Before that, I just finished my practical project in the university on “B-Spline curve surface fitting ” under our open-source framework CONRAD(JAVA). I will soon commit the code to Github. I’m quite familiar with Splines and other geometry modelling concepts; Also I’m quite comfortable with C++ since I’m using it on a daily base for my Master thesis from last October. Therefore, your topics seem to fit my interest and capacity perfectly.<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'><o:p> </o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>About the topic:<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>The project tasks sound clear to me. But I have some problem with accessing your source code. Could you please kindly give me some tutorial? Also, it seems you already have the BSplineGeometry class. I assume you already have the basis functions of B-splines so the splines can be easily built given the knot vector and the control points. I have some thoughts on “small projects to get started”. Some functions that can be implemented:<o:p></o:p></span></p><p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1;background:white'><![if !supportLists]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'><span style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>Evalution at a certain parameter (de Boor Algorithm)<o:p></o:p></span></p><p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1;background:white'><![if !supportLists]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'><span style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>Knot addtiton and deletion (Boehm Algorithm)<o:p></o:p></span></p><p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1;background:white'><![if !supportLists]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'><span style='mso-list:Ignore'>3.<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>Fitting to a list of points(global or local interpolation)<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'><o:p> </o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:10.5pt;font-family:"Arial",sans-serif;color:#222222'>Thanks for your time and hope to hear from you soon!<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
