Rose- Week 5

Rose Week 5:

• 3D Web Scenes
  • More intuitive to interpret than 2D maps
  • Enables fasters communication
  • More interesting and engaging
  • Important for design, simulation, many industries
  • A critical component of VR and AR
• Visual effects
  • Photorealistic(real world)
  • Cartographic(representative)
• Viewing modes
  • Global
    • Global Coordinate System(WGS84): can display above the ground features, can be enable to display under the ground features
  • Local
    • Projected Coordinate systems: Can display above and under the ground feature
• 3D view: four main elements
  • Surfaces: provide ground elevation
  • Features: situated one, above, or below the surfaces
  • Textures: provide exterior or interior covers of your 3D features
  • Atmospheric effects
• Web scenes
  • Equivalent to web maps in 2D
  • Essential for 3D apps ArcGIS platform
  • Collection of layers, environment settings and slides
• Scenes services/layers
  • Scalable cache of graphics, styles, and attributes
• I3S(indexed 3d scene)
  • Open specification for scene layer 
• Layers in web scenes 
• 2D layers
  • Feature layers: can display in 3D symbols
  • Map image layers, vector tile layers, raster tile layers, image layers
• Scene service/layers
  • Can hold large volumes of features in an open format(i3s0 that is suitable for webs streaming
  • Leads features progressively, starting from coarse representations and refines them to higher detail as necessary for close-up views
• Web scene layers
  • 3D object scene layers, building scene layers, integrated mesh scene layers, point cloud scene layer, point scene layers, voxel scene layer
• Virtual reality(VR)
  • Uses headsets or multi-projected environments to generate 3D views, sounds, and other sensation that simulate a users physical presence in virtual or imaginary environment
  • Users are immersed “inside” the maps, and can “look” and “move” around the artificial world and even interact with virtual features or items
• XR
  • Refers to all real-and-virtual combined environments and human-machine interactions, generated by computer technology and wearables, where the X represents a variable for any current or future spatial technologies. Includes AR, VR, and MR
  • MR is merging of real and virtual worlds to produce new environments and visualizations, where physical and digital objects coexist and interact in real time. AR takes place in the physical world, with information or objects added virtually, like an overlay
  • VR immerses you in a fully virtual world without the intervention of the physical world
  • MR does not exclusively take place in either the physical world or virtual, but rather a hybrid of AR and VR
• Metaverse
  • A network of #D virtual worlds focused on social connection
  • The COVID-19 pandemic has accelerated the interest in developing metaverses
  • GIS professionals can play important role in building metaverses
• ArcGIS GeoBIM
  • Bridges gap between GIS and BIM using a web-to-web client integration approach by connecting ArcGIS with Autodesk Construction and BIM 360
  • Provides a solution for exploring BIM, engineering documents, and project management issues in a geographic context

An app that I would create applying this type of knowledge would be possible layouts and structures to a dorm room based on the furniture that is provided in order to find the best setup to fit your needs without constantly rearranging it by hand.
