Tristix Grids

All models and representations of tristix are finite subsets of an infinite tristix arrangement. The geometry of tristix models can be efficiently designed in 2-dimensions, as each axis has a repeating pattern that lays on the body-centered cubic lattice.

To start designing tristix, patterns can be drawn on a triangular grid (figure 107). There are infinite possible designs that can be used to create a tristix model, but it is good to start with simple polygons before moving on to more complex designs (figure 102).

Tristix can be made with a different pattern on each axis, but this will cause the arrangement to have less symmetry. Not all of the possible patterns create stable tristix arrangements that hold themselves apart in each direction. Comparing patterns using paper templates can be a useful way to save time and materials, but is not usually necessary for simple tristix investigations.

Moving along, in the next blog post we will dive even deeper into tristix geometry.
