Can anyone tell me how to calculate the parameter values of a curve edge at two endpoints, respectively? Below is the mesh data of a circle:<br /> <br /> # Major &amp; minor version<br /> 0 1 <br /> 1 # number of tags<br /> # Tags<br /> 5 mesh1 <br /> 1 # number of types<br /> # Types<br /> 3 obj <br /> <br /> # --------- Object 0 ----------<br /> <br /> 0 0 1 <br /> 4 Mesh # class<br /> 2 # version<br /> 2 # sdim<br /> 14 # number of mesh points<br /> 0 # lowest mesh point index<br /> <br /> # Mesh point coordinates<br /> 0.54004497593511991 -0.037779200720473034 <br /> 1 0 <br /> 0.70711341916808013 0.70710014314270009 <br /> 0.18343216591831446 0.25870137743794869 <br /> 0.24479262775166793 -0.3540242553652021 <br /> 0.70710014314270009 -0.70711341916808013 <br /> -0.25920024933402869 0.33623073487269922 <br /> 0 1 <br /> -0.20661414623779478 -0.28393003437540593 <br /> 0 -1 <br /> -0.56571912320796292 -0.0007310878671271309 <br /> -0.70710014314270009 0.70711341916808013 <br /> -0.70711341916808013 -0.70710014314270009 <br /> -1 0 <br /> <br /> 3 # number of element types<br /> <br /> # Type #0<br /> <br /> 3 vtx # type name<br /> <br /> <br /> 1 # number of nodes per element<br /> 4 # number of elements<br /> # Elements<br /> 1 <br /> 7 <br /> 9 <br /> 13 <br /> <br /> 1 # number of parameter values per element<br /> 0 # number of parameters<br /> # Parameters<br /> <br /> 4 # number of geometric entity indices<br /> # Geometric entity indices<br /> 3 <br /> 2 <br /> 1 <br /> 0 <br /> <br /> 0 # number of up/down pairs<br /> # Up/down<br /> <br /> # Type #1<br /> <br /> 3 edg # type name<br /> <br /> <br /> 2 # number of nodes per element<br /> 8 # number of elements<br /> # Elements<br /> 2 1 <br /> 1 5 <br /> 7 2 <br /> 5 9 <br /> 11 7 <br /> 9 12 <br /> 12 13 <br /> 13 11 <br /> <br /> 2 # number of parameter values per element<br /> 8 # number of parameters<br /> # Parameters<br /> 0.50000566589823847 1 <br /> 0 0.50000566589823847 <br /> 0 0.50000566589823847 &lt;------ How to obtain them? <br /> 0.50000566589823847 1 <br /> 0.50000566589823847 1 <br /> 0 0.50000566589823847 <br /> 0.50000566589823847 1 <br /> 0 0.50000566589823847 <br /> <br /> Thanks!
