generative modeling for Rhino
for the love of God what is the name of the slider that will accurately allow you to adjust the t value along a curve. Ive used it as recently as last night but cannot find it again... this is beyond annoying.
its not the node i need, but the slider you plug into the input "t" it visually looks something like a gradient and if you click into it it has prebuilt selections for zero .25, .5, .75 parameters.
note: i tired to rig a defacto version by taking the curve length multiplied by a slider value with a range of 0.0 to 1.0... lets say .57 and plugging that return into the t... to no avail
The component is "Point On Curve." (Curve Tab -> Analysis -> Point On Curve) If you want to do the same thing with the Evaluate Curve component, right click on "C" and select reparameterize. This will redefine the curve's domain between 0 and 1.
1) Right Click the C character and scroll all the way down, you will see and option that says: Reparameterize, check that ok,
2) then, drag and drop a numeric slider and connect it to the t input. Now you can control the Eval from 0 to 1, so, 0.50 would be the center or mid point of the curve.
Hope it helps...
jesus, it was staring me right in the face! thanks everyone, and for the tip to reparameratize the curve... i didnt know about that
