This also means the thickness changes depending on the angle.</div><div>I figured I can control the thickness by using sin (x+c) with c being an adjusting angle so that I get 1 for max thickness and 0 at an ending angle.</div><div>I think I can also control the displacement toward the rear based on the angle, too.</div><div>So all that's
left is the elliptic extrusion. Can someone give me an example, please?<br></div><div><br></div><div><br></div><div class="yiv864585918MsoNormal"><span style="font-family:"serif";"> </span></div><div class="yiv864585918MsoNormal"><span style="color: rgb(127, 127, 127);" lang="TR">Sincerely,</span></div><div class="yiv864585918MsoNormal"><span style="color:#7F7F7F;" lang="TR">Mira Lennis<br></span></div></div></body></html>
