Grasshopper

algorithmic modeling for Rhino

Hi there, i've been trying to do the following tutorial (http://diverg.co/blog/2012/02/17/adaptive-grasshopper-skin-part-1-2/) which looks pretty simple but i'm stuck at stage 4 already!!!

Has anyone completed this tutorial before or could someone show me how to find the centre points of the divided surfaces?

Hello Jamie you have everything correct.

like the tutorial describes ''To do this the number of divisions of the divide curve component needs to be set to 2. This returns the end points and the midpoint of each curve.'' so you have each three point start middle end in a list for all these curves (after explode). all these lists with the three point create a data tree ( a collection of lists)

so you need to do the following to access the middle point

this uses the list item component with index 1 (the middle point).

alternatively you can use instead of divide curve,  evaluate curve at t=0.5, don't forget to reparemeterise the curve input and to turn preview off for the previous components.

Ok thanks for the feedback Alex!

I'm currently stuck now on how to complete the next stage of the tutorial (http://diverg.co/blog/2012/02/24/adaptive-grasshopper-skin-part-2/). I've tried to contact the Author of the blog to see if i can get a copy of the completed script as I'm quite new to grasshopper and don't think there's enough information in each step for me to continue.

these tutorials have only description and sometimes some steps are considered not to be mentioned. why don't you try some other source of tutorials.

the following cover many topics
