generative modeling for Rhino
Hi, I'm trying to build a control point on the
field inside the sphere and beyond. I can not:(, please help.
hi alex, i don't understand the question would you expand it a bit. maybe include a sketch or a file please.
1,1,1 is the point on the sphere ?!
I can not understand why the point x = 1, y = 1, z = 1 (point2.bmp)
outside the sphere?
Why would it be inside?
a point at 1,1,1 is about 1.73 units away from 0,0,0. Since 1.73 > sphere radius of 1, it is outside the sphere.
Are all inside the sphere (or rather on the sphere, not sure if that counts).
they are in sphere surface domain :P
thanks Brian for the help, but 1,1,1 is the point on the sphere
the point x = 1, y = 1, z = 1 is neither inside nor on a sphere with an origin of 0,0,0 and a radius of 1. What is it that you are trying to do?
put a point 1,1,1 on the sphere
you can do a variety of things to put a point on a sphere, but you can never have a point at 1,1,1 be on a sphere with a radius of 1 at origin 0,0,0.
Use brep closest point to find the closest point on the sphere to 1,1,1
draw a line from the origin to 1,1,1 and intersect it with the sphere
use the evaluate surface component to create one or more points on the sphere
Brian, thank you for this example (BRep ). This elegant and beautiful solution. Thank you for your help.
