WEEK 1 ATTRACTOR POINTS
This week the task was to create attractor points. In this image the attractor point with circles overlapping created a nice moire effect. Finally the circles were used to produce spheres.
The circles were then turned to spheres and applied to lofted curves.

Then two attractor points were used to give a more dynamic interaction of the sphere sizes

WEEK 1 ATTRACTOR POINTS - Colour
This surface was created by using two curves, dividing them, making biarcs between the points and lofting two surfaces from each arc.
The surface was divided and then a colour gradient was used to colour the points on the surface based on their distance from the attractor point. 6

WEEK 2 - Heatherwick Cathedral
A base surface was made with curves and then lofted and capped. in the centre of this a sphere was surface divided and then had lines built from these points. The original base surface was scaled to give a limit to the lines. Both surface were used to find the intersect of the curves with the surfaces.
Then curves were made from the inner points to the outer points. Finally they were piped.

WEEK 2 - Mesh
To experiment with mesh tools this shape was constructed in rhino and then referenced in grasshopper as a brep.
The brep was then meshed and the vertices were welded. Smooth mesh was then used to get this weir organic shape. The colourful shape was an experiment with the surface spray-paint tool. 10

WEEK 2 - Array, Offset
To experiment with the array and offset tool, I created a curve and then found its planarity and the array this curve on another curve. I then found the planarity of these curves and offset them and lofted between them. The offset data had to be flattened to make a frame surface with the loft tool.

WEEK 2 - Analyse surface
Experimenting with evaluating surfaces I came up with these forms. I used a range tool and a point component to create multiple points along the surface for the UV value of the eval-surface command. The surface was reparamatised to make the UV values on the surface go from 0-1. The first form on the left was made by evaluating the surface twice once with a range along the x axis and once with a range on the y. Then using the geodesic tool I made curves along the surface and lofted them. The form on the right and below was created by instead of creating a range of point on the y axis to evaluate on the surface I made a range on the Z axis. I then changed the y value to be 0.8 so the z points were almost reaching the other curve.

WEEK 3 IMAGE SAMPLER
This sketch was an exploration with the image sampler tool. I first made circles on a grid where the radius was dictated by the image sampler. I then tried spheres. I also tried moving the spheres in the z direction by the image sampler values. I then used this set of values to also define cones and extrude the circles.

Gradient Descent
These sketches were experiments in gradients descent and fields. The above two sketches were gradient descent just mapping the flow of a liquid over the surface. The next sketches were experiments in anenome and spin fields. By differening the strength and radius of the field and the numebr of fields many different sketches were created.

ALGORITHMIC SKETCHBOOK
The two sketches on the left that look like a huge swirling mass was created by putting a spin field on each random point that populates the surface. the other sketches were made with different spin fields with radius overlapping and not overlapping.

L-Systems
These sketches were an exploration on L-systems, beginning with basic patterns and then exploring more repetitions and different patterns. The stair like pattern was made by drawing the lines on a different axis to the orientation direction.

Week 5 - Albahar Tower
This sketch was an exploration of the technique of scaled panels such as those in the Albahar tower. We explored ways of dictating the scale level based on the orientation of the panels.
22
ALGORITHMIC SKETCHBOOK
These sketches took the same principle and applied it to different geometries. I also explored the effects of changing the orientation of the plane that I am using to manipulate the scale of the panels. Some of the sketches also changed the orientation of the panels themselves.

ALGORITHMIC SKETCHBOOK
This sketch is more like the Albahar tower in the way that the scale of the panels is dictated by a XZ plane so that the control of incoming light is achieved.

Week 6 - SAHMRI
This algorithmic sketch attempted to rebuild a basic version of the exterior facade of the SAHMRI building. It was interesting the way the data for the panelling had to be split to be able to manipulate it. I manipulated the way the panels pointed and how much they extended..
