I created a working 3D line-drawing algorithm that uses only fixed point numbers and integers. This will be used once the z-stage is up and running.

By my skills in fine craftsmanship and creative prowess, I have cut these two rectangles into this piece of black paper:

This will be used for the aperture demonstration photos.

We got the z-stage!

Possible way to control digitally through USB with an Arduino:
Arduino USB Shield

We looked at occlusion effects from a two different angles, vertical and horizontal. Variation could be seen when the mirrors were vertical, but when the mirrors were horizontal, there was very little variation…

Glass about centered

Most variation we got (glass rotated 30 degrees)

Here are some pictures of occlusion control. Unfortunately, they are not very bright…

The main effect seems to be a change in brightness when viewed from different angles, as expected.

Still working on the automation of speed and acceleration tests…

This week, we looked into changing the occlusion with a piece of glass attached to a rotating stand. Here are some results:

This week was spent mostly working on code for velocity and acceleration testing and automation.

We can crop the ruler out of images now:

Ruler:

No ruler:

And we can make particles move in the path that we need for testing.
