cyclical data detected, l parametre is recursive

the definition always worked very well with the refered object in rhino, and i kept changing the shift value to see different effect. i didnt do anything else to the definition and the object, but the definition couldnt generate anymore the result suddenly when i chose the boolean as false as i always did, but if i chose true, it worked but not the effect i want. and all the components are grey,means that it works ? but without result! and i found blow the message of cyclical date dected, L…See More

Matthew Sederberg replied to yewei's discussion problem of paneling the converted tspline surface

"Yewei, As far as I know, paneling tools only work on topologically rectangular areas. Since this t-spline does not have a rectangular topology (you had some star points in it), that is why the entire surface can't be paneled at once. Matt"

"even the violet surf couldnt be loaded in Gh, But why? it's been explored!! i upload also the definition of panel tool from the manual of gh primer here."

"thanks matthew! i see....sign... i supposed that when ts srf converts into nurbs, the ts srf turns normal ... since i have lost the model with tsplines srf,so i set the U,V interval with the same parametric, and the panels are joined completely on…"

Matthew Sederberg replied to yewei's discussion problem of paneling the converted tspline surface

"Hi, you can use the tsSetSurfaceLayout command to see how the T-spline surface will be split up into rectangular NURBS surfaces. You can change this layout to better suit what you are trying to do. Unfortunately, grasshopper and Rhino don't…"

problem of paneling the converted tspline surface

hi all,only want to apply the panelling tool to the cutted surface made by tspline.but gh didn't recognise the whole surface as a single surface. like when using _curveonsrf command, it reads the one surface as pieces of srf components. but how to set the interval in this case???i am sure someone has met this problem, any suggestion and idea is appreciated. many thanks.See More

a question about extract item from sub-branch

ciao!!i have 7 isocurves extracted on which i definite the points with a certain interval .and i hope that the 1st interpolated curve connecting the 1st point on the 1st isocurve, the 2nd point of the 2nd isocurve...till the 7th point of the 7th isocurve (of course wrapped). and the 2nd interpolated curve connecting the 2nd point on the 1st isocurve, 3rd pint on the 2nd isocurve....till all the points finish.and if there are no enough points on one isocurve, that isocurve will be ignored. i…See More

Evolver for minimal surface! any ideas and helps!

hi all,i followed the post of http://grasshopper3d.ning.com/forum/topics/minimal-surfaces?id=2985220%3ATopic%3A22138&page=2#comments and found that there mentioned rhinomembrane and evolver, for rhinomembrane is not free and i don't know how long will be the demo, so i want to try my luck with evolver, but after i have installed it, i found that it should use OpenGL/GLUT…See More
