Environmental patterning

External geometry (also called integrated geometry or embedded geometry) can be described as a form of a-typical psychedelic geometry which differs from standard geometry through the way it is manifested. Instead of being independent from the external environment and floating in front of one's vision across a separate translucent veil, it is comprised of and embedded within parts of the external environment.

This results in certain textures such as grass, carpets, asphalt, tree branches and dense vegetation forming into extremely complex geometric structures that are comprised of the original material which they are manifesting from. These structures tend to be partially symmetrical in nature, but also include form constants, fractals and disorganized geometric patterns.

The experience of this component is distinct from traditional geometry as it does not occur within its standardized levelling system and therefore seems to be an entirely separate subjective effect. It is worth noting that this component may be the result of a synergy between symmetrical texture repetition, 3-dimensional textures and geometry.
