algorithmic modeling for Rhino
Hello , please check picture first ,
It is simple , we always use Rhino curve G2 match , it is fast because G1 points are same distance to G0
Now I hope G1 points to G0 distance are different (Variable match ) , then how to count G2 points position ?
I tried a lot and I asked some rhino expert too but it seems extreme hard . ( at least for me )
I have wrote a GH definition for G1 same distance work , now if some one interested to challenge variable match , please just draw two 5 degree nurbs curve to test . :-)
I have no idea because I am poor in calculus math , but I hope to some one help .
Hello , Tom ,
To the point where second derivate of curve A at p0 equals second derivate of B at q0.
I understand it need math of "derivate" , Just I don't know how to write it as code or GHuser .. So at present , I use galapagos to get similar position of G2-B
You can find my email address ? when I get test , I will send my GH file (Curve Match) for your reference too . Thanks
Hello , Tom ,
Oh , you are ahead of me far away . :-)
No problem I just need small requirement , for example G1 G2 only .
Your Match curve is attractive , just I can not spend some weeks like you . I am quite busy on biz too .
AST.dll seems interesting , just same no time to touch too .
About ' the derivate of a nurbscurve ' , is it the same to use command "curvature" and mark the circle ?
Hello Tom ,
Wow , it seems that you play a lot software , for me , Rhino + Grasshopper is enough . I like G2 smooth only , G3 is not necessary to me me .
I studied advanced math in university too , just forgot after some years biz ...Now I find out I love grasshopper much .
I like to wait your unofficial astools :) you may send to winsionliang AT gmail.com ,
For mutual benifit , I will send my two definition of GH Curve match ghuser to you . Thanks Winsion
Hi , Tom ,
Here is my simple GH mach curve definition . the EX version has small issue but almost enough . :-p
My version is beta and beta too , haha~
Plane seems necessary to me because it can rotate the curve for all situation .
Pls notice G2 offset input is bool . (see pic)
For "use crossproduct of tan and cur vector and rotate for 0.5 pi" , it might be default value .
I will find time to see vector rotation as well as your module . Thanks
