A compositional visualization system comprises a sensor to collect contextual information, a particle generator to generate a first stream of one or more types of particles, and a detector to receive a second stream of one or more detectable products. The second stream is generated by interaction of the first stream with the environment. The system further comprises computer-executable instructions to cause the system to transform the received second stream into compositional data, and merge the compositional data with the contextual information to generate a merged digital representation. The merged digital representation can be displayed at one or more devices and can also be used directly to drive autonomous robotic systems.
