Great introduction to Grasshopper: http://grasshopperprimer.com/ and https://parametrichouse.com/

A complete overview of Grasshopper Components can be found here: https://rhino.github.io/

Exercise A:

Premise: design Design a parametric cup. Create a definition to control height, top &and bottom radius and wall thickness through sliders.

1. set Set basepoint in rhino and connect to grasshopper
2. create Create sliders for heithheight, top &and bottom radius and wall thickness
3. move Move (copy) the centerpoints centre points for the all circles but , except the lower outer radius
4. subtract Subtract the wallthickness wall thickness for the inner circles
5. create Create a loft (mind the order)
   loft type (O) set to "straigtstraight"
6. create Create the bottom inner and outer surface with "boundary surface"
7. join Join all surfaces
8. "bake"

Exercise B: Working with attractors

Premise: Control the diameter of circles by the proximity to an object

1.  Create Create a "rectangular" grid
2. control Control Size and Extend through sliders
3. create Create circles on the intersection points (p)
4. control Control the radius of the circles through the distance to a point set in rhino
   use a division or mapping to adjust the scale

...

1. connect a mesh from rhino
2. "deconstruct mesh"
3. "deconstruct face"
4. read out the edges through "list items"

Exercise D:

Creating 3D sine waves. Follow the grasshopper sketch to create either a sine or sinc wave in a 3D surface or solid.
