Ah, yes. Stereoscopic vision.

This is a follow-up to my previous article, in which we explored the choice of PCB placement in order to get an optimal visibility.

My previous analysis only covered the case of a punctual point of view. However, most people have two eyes, which provide a double point of view and could increase our coverage of space. It is to be pointed out that a point of space seen by one eye does not provide depth information to the brain, however let us assume that our image perception is smart enough to overcome this limit.

In the following simulation, we used a typical eye distance of 6 cm. To understand the different configurations, please refer to this article.

As you can see, the dispositions that seem to benefit the most of stereoscopic vision are modulo forests, particularly the ones where the repartition of PCBs seems the most uniform. The parallax effect is all the stongest when PCBs hiding each other are far away in the axis of vision. Modulo forests with k = 3 and 11 seem to be good candidates as the front portion of the cylinder is (almost) complete in both cases.
