Improved geomechanical model visualization and interpretation using a combined mixed reality-virtual reality approach

岩土工程中的数值模拟技术近年来取得了长足的进步，因为它已经有了获得所需输入数据的方法。一个主要的挑战仍然是确保三维数据的最佳视图，以便专家用户有效地解释结果，并促进与客户和非专业人员的理解和沟通。这项NSERC Engage研究将尝试提供最先进的地理可视化工具，用于查看力学建模代码中的数据。特别是，混合和虚拟现实硬件（微软HoloLens）和软件将用于交互式观看三维混合现实全息图像的数值建模输入和输出数据。从使用立体分析方法对地质结构进行简单的全息观察到使用极限平衡楔形分析提高对块体破坏运动学的理解，将讨论一系列三维岩土工程场景。为newSlide3D和RS3等更复杂的三维坡度分析方法输入的井眼和地表几何数据将以全息方式进行查询，并使用混合现实延时视频功能呈现分析阶段的结果。全息图的语音激活将允许用户逐步通过岩土分析，从而大大改善通信和理解。还将探索虚拟现实方法，使用户可以在虚拟沉浸式环境中查看模型输入和输出。SFU地理可视化研究人员将与Rocscience软件工程师合作，尝试在地质力学模型展示方面提供一种范式转变，为用户社区带来潜在的重大利益。

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.
