Abstract: Computing devices for automatic placement and arrangement of objects in computer-based 3D environments are disclosed herein. In one embodiment, a computing device is configured to provide, on a display, a user interface containing a work area having a template of a 3D environment and a gallery containing models of two-dimensional (2D) or 3D content items. The computing device can then detect, via the user interface, a user input selecting one of the models from the gallery to be inserted as an object into the template of the 3D environment. In response to detecting the user input, the computing device can render and surface on the display, a graphical representation of the 2D or 3D content item corresponding to the selected model at a location along a circular arc spaced apart from the default viewer position of a viewer of the 3D environment by a preset radial distance.

Abstract: Computer-implemented methods and systems for replication of data between mirrored data sites are provided. An exemplary method may comprise receiving a data object at a mirrored data site, the mirrored data site including one or more data nodes. The data objects are replicated to the one or more data nodes internally. Then, a data object reference associated with the data object is generated. The reference referring to the data object is queued for transmission to all other mirrored data sites. The data object reference associated with the data object is transmitted to the other mirrored data sites. When the data object is received at each mirrored data site, it is replicated to one or more data nodes within the site. After transmitting the data object, the data object reference is discarded.

Abstract: Method of performing a 3-D seismic survey using a plurality of vibroseis sources, and an array of seismic sensors arranged within a survey area. Each vibroseis source emits a distinctive acoustic signal and each seismic sensor of the array is in a continuous state of readiness to detect reflected acoustic signals. The method includes assigning vibroseis points (VPs) to each vibroseis source, moving each vibroseis source to assigned VPs where the vibroseis source emits an acoustic signal, recording the emission time of the acoustic signal by each vibroseis source at its assigned VPs together with the geographic position of the assigned VPs, continuously listening for reflected acoustic signals using the seismic sensors and recording a time domain record of the reflected acoustic signals received by each seismic sensor. Reflected acoustic signals associated with emission of an acoustic signal by a vibroseis source at an assigned VP are then determined.
