*'''Intricate vs. simplistic''' - Geometry can either present itself as incomprehensibly intricate and complex in its appearance or simplistic, basic and comprehensible even at higher doses. For example, the geometry associated with [[dissociative]]s tends to be consistently overly simplistic in form while most psychedelics are significantly more intricate. | *'''Intricate vs. simplistic''' - Geometry can either present itself as incomprehensibly intricate and complex in its appearance or simplistic, basic and comprehensible even at higher doses.

*'''Algorithmic vs. abstract''' - Geometry can either appear to follow mathematical rules and logically consistent forms in its design (which often results in high amounts of fractals and semi-predictable shapes). In contrast to this, however, geometry can also be completely abstract or random in its appearance in a way that contains an infinite amount of completely unpredictable variety. | *'''Algorithmic vs. abstract''' - Geometry can either appear to follow mathematical rules and logically consistent forms in its design (which often results in high amounts of fractals and semi-predictable shapes).

*'''Non-immersive vs. immersive''' - Geometry can be manifested in front of one's face | *'''Non-immersive vs. immersive''' - Geometry can be manifested in front of one's face in a manner which feels separate and as if it was being presented on some screen without a distinct sense of size or distance attributed to it. In contrast, geometry can feel as if one is completely immersed in and surrounded by it with a distinct sense of attributed size and distance. | ||
*'''Consistent vs. progressive''' - Geometry can be manifested as consistent and steady in its intensity, complexity and visibility regardless of disturbances within the external environment. In contrast, however, it can manifest as progressive in its intensity which means that disturbances and sensory input such as bright lights, loud noises and distractions within the external environment will prevent or cut off the intensity, complexity and visibility from building up to its limit whilst darkness will cause it to steadily rise in complexity. | *'''Consistent vs. progressive''' - Geometry can be manifested as consistent and steady in its intensity, complexity and visibility regardless of disturbances within the external environment.
