After a few lessons of grasshopper, I am quite amazed about what and how grasshopper works.
Repetitive tessellation, in particularly. I understand this could be done on rhino, however it takes
quite awhile it get it tessellate accurately while grasshopper we could just do it instantly with the best results.
I did some pattern study on how could simple geometric shapes tessellate and form an overall visual effect
on illustrator and then try translating it into grasshopper definition.
Took me quite a while to figure out, and realised that I could tessellate 2D instantly
(vector > grid >hexagonal). Then to enhance it I gave it a slight raise for point z, to make it look 3D-ish
(allowing all 6 points to meet at the centre and create individual surface.
Thus it turns out to be like the above, a very subtle 3D tessellation done using hexagonal shape.
Creating the definition in grasshopper.
I did some simple info graph and categorizing the steps hope it helps for future references.
