VECTOR ARCHITECTURE
My research began by experimenting with different fluids studying their properties and how its interactions act as a trigger for a dynamic responsive tool. Advancing my research on fluids into digital to study the complex interactions that occur within a city, such as different types of infrastructural flows, crowds as fluids masses and program navigation, I started reading fluids as vector fields to choreograph this complex systems into the urban scale.

Anaglyphic processes are not really able to reconstruct full-color 3D images. Colors which are combinations of red-green (yellow);and red-blue (magenta) would reproduce. However, to get full-color photos or movies, a polarizing filter system (or an adapted Russian LCD shutter system) must be used. Polarizing filters steer the vibrations of light analogous to a Window blind. Two synchronized projectors are used, overlapping the images into an aluminum screen. The shutter system, on the other hand, switches back and forth rapidly for left- and right-eye images, synchronized to the image input, and alternating so fast that the eye cannot detect the changes. This is similar to how LCD shutter glasses work.

Using Zorn’s Lemma (which is equivalent to the axiom of choice), it can be proven that every vector space has a basis. It follows from the ultrafilter lemma, which is weaker than the
axiom of choice, that all bases of a given vector space have the same cardinality. Thus vector spaces over a given field are fixed up to isomorphism by a single cardinal number (called the dimension of the vector space) representing the size of the basis. For instance, the real finite-dimensional vector spaces are just R0, R1, R2, R3, …. The dimension of the real vector space R3 is three.
