Numerical modelling techniques in geotechnical engineering have advanced considerably in recent years ashave methods of obtaining the required input data. A major challenge remains in ensuring optimal viewing ofthree-dimensional data to allow efficient interpretation of results by the expert user and also to facilitateimproved understanding and communication to the client and non-specialist.This NSERC Engage research will attempt to provide state-of-the-art geovisualization tools for viewing data ingeomechanical modelling codes. In particular, Mixed and Virtual reality hardware (Microsoft HoloLens) andsoftware will be used to allow interactive viewing of three dimensional mixed reality holographic images ofnumerical modelling input and output data. A range of three-dimensional geotechnical scenarios will beaddressed from the simple holographic viewing of geological structures using stereographic analysis methodsto improved understanding of block failure kinematics using limit equilibrium wedge analyses. Input boreholeand surface geometry data for more complex three-dimensional slope analysis methods such as the newSlide3D and RS3 will be interrogated holographically and the results of stages in analyses presented usingmixed reality time-lapse-video capabilities. Voice activation of holographs will allow the user to step throughgeotechnical analyses to allow major improvements in communication and understanding.Virtual reality methods will also be explored to allow the user to view model input and output in a virtualimmersive environment. Working with Rocscience software engineers the SFU geovisualisation researcherswill attempt to provide a paradigm shift in geomechanical model presentation with potential major benefits tothe user community.
