Project 2b

For this week, I felt draw initially to the attractor point example.  Going through this example, and beginning to understand how the effect was achieved, I wanted to explore how to get this effect with even more points and on a three dimensional object.

With this initial exploration, I was interested how a grid of cubes could be made, with there spacing dependent on a factor of the initial grid spacing, and how attractor points could effect the level of extrusion of these cubes.

Interested by the effect of manipulating multiple geometries, I wanted to take this effect and try and apply it with data extracted from an image.  I discovered that through an image sampler definition, data based on the RGB value was able to be extracted and used to determine the amount of extrusion of a cube.

With this method I was able to take the image of the painting used in past weeks, and use that data to determine the height of a field of cubes.  Further interested by this application, I wanted to see if i could make this definition further manipulable, applicable on an organic surface.

After some trial and error, I was able to take any surface, divide it based on slider values I determine, and extrude holes that vary in radius based on an image.  Certain things like creating a normal plain at each point, and splitting the surface based on extracted curves from a cylinder had to be developed in order to achieve the desired effect.  One thing that I would like to do, is to try and remake this definition more efficient.  This current attempt became very heavy to work with.
