WEEK 1 SOUMAYA TASK EXAMPLE:
4
VERSION 1: The length of the normal lines were decreased as well as the radius of the sphered. The original curves forming the loft were rotated in the x and z axis.
VERSION 2: The slider for the normal points extruding from the lofted surface was changed to zero and the radius of the spheres was increased to cover the surface.
5
WEEK 1 SOUMAYA TASK VERSION 3: The sphere geometry was changed to a cone which was attached to the end of the normal points to face perpendicular to the shape. The curves forming the 3d vase were then rotated to twist the form.
6
VERSION 4: The cones were replaced with cylinders and the density of the loft division points was increased to form the ruffle effect.
7
VERSION 5: Surfaces were added to the 2D circles placed on the divided loft points. The loft surface was then offset by 5 units.
8
WEEK 1 SOUMAYA TASK
VERSION 6: The original loft was removed and the scale of the three curves was adjusted and rotated.

WEEK 2 SOUMAYA TASK 2
This task involved creating a grid of points and setting an attractor point (see grid above. This size gradation effect radiating from the point was applied to the surface of the Soumaya task, meaning that the spheres furthest from the attractor point would be the biggest.

WEEK 3 REMAPPING TASK 12
WEEK 4 IMAGE SAMPLER This weeks task was to map an image onto a rectangular grid using circles that vary in size depending on the amount of black or white in the pixel.

WEEK 6 MESH RELAXATION
Item Index: 8763; 2946 500; 6783 244 Vector Loads: Y: 0 Z:-1
This task involved re-arranging a Kangaroo mesh component to achieve different results. Different variables were changed to produce curved and jagged drooping shapes. For example, in some outcomes the line and anchor strength were modified to increase the slack in the dropped arcs and the square mesh was triangulated.
