Abstract: A computer-implemented is described. The method can include receiving, at a computing device having one or more processors, a first input from a first user. The first input can be indicative of a first avatar representing the first user. The method can also include receiving, at the computing device, a second input from a second user. The second input can be indicative of a second avatar representing the second user. The method can also include receiving, at the computing device, a third input from one of the first user and the second user. The third input can be indicative of a primary virtual environment for the first avatar and the second avatar. The method can also include outputting, at the computing device, a first video to the first user of the primary virtual environment. The first video can be representative of a first first-person viewpoint of the primary virtual environment.

Abstract: The invention is a composite of interdependent engineering methods for earthen fill engineering and construction. The invention includes the development, utilization, and correlation of actual, cumulative field compaction energies, unique to and based on field combination-specific variables of any combination but including all of the following: soil type, compactor type, lift thickness, moisture content, and soil amendment type and mix.
