         per pixel down to 0.2’ per pixel
         Material Generated using World File Information

         Aerial Materials applied to various TINs
Material Creation
   Existing Structure
         Hand held Photos Taken of Buildings along Corridor
         Images Cropped and Compressed
         Some Buildings needed to have a Mosaic of Multiple Images
         Each face of each Building had an Image created
         Each face of each Building had a Material Defined
         Material were applied to 3-D Building Faces
Material Creation
   Other existing features

         Signs

         Gas pumps
         Evergreen Trees

         Etc. Too many to
         explain in a half hour
Material Creation

    Create material from sign face image in MicroStation
    Attach sign faces to elements
Material Creation
   Proposed Features

Predefined Materials
   MicroStation Defaults

         Vast selection of premade Materials

         Many options for changing
         appearances of Materials

   Premade Features
         Google 3D Warehouse
         – Sketch Up
         Online User Communities

         ArcVision RPCs
Animation
   Determine Area of interest

         Primary Focus of Animation Determined
Animation
   Create Camera Paths
      Area of interest determines Camera Target

      Target of Camera can be fixed or dynamic

      Camera path created with MicroStation Linear Element

      Speed of camera determined
      Many test runs made and path
      altered
Animation
   Create “Actors”

    Actors are basically all of the moving features

    Determine what items need to move
    Choreography of elements determined by Camera

    Single direction\speed Actors are easy

    Parametric Motion takes some skill

    Many renderings created

    Many actors Altered based on Test Renders
Create Animation
   Create Individual Frames

         Referencing Data over a Network

         Setup Distributive Processing
         Choreograph up to 32 individual computers

         Excessive number of Energy Drinks
Create Animation
   Combine Frames into a Video

         Add Individual Rendered Frames in to Video Software

         Replace Bad Frames with Corrected Frames
         Final Tweaks to timing of Video

         Create Animation Video
Create Animation
   Edit Video for Presentation

         Combine Finished Video Segments

         Create Titles and Transitions
         Add sounds

         Add music

         Create Final Video Product
Lessons Learned
   Hind Site is 20\20
         Camera View determines everything

         We created an entire Historic Village that was never seen
         The Survey Crew spent Hours collecting unused data
         Overall too much time was spent developing areas that
         never appeared in the animation sequences.
Lessons Learned
   More is NOT better – 200 photorealistic
    trees Vs. 1 rectangle.
         Tree Row consisting of a few hundred Trees
         Render the view 1 time
         Create a Material from Rendered Frame
         Add a Rectangle that will cover the Tree Row
         Apply Material to Rectangle
Lessons Learned
   Perforated tubes for sign posts Vs. Solid
    shape with image overlay.
     Too much detail lead to slow render times
Improvements in the Process
   Working with a finished Survey

      Save time - Time Spent Rendering not Surveying
                   Specialists in data collection work
                   much more efficiently that novices

      Better accuracy - Data collection is Survey Quality
                        Stereo Compilation is tricky business.
                        Novice Compilation data is Sketchy at best
Improvements in the Process
   Working with a finished Design

       In most cases if a Design is complete it could
          drastically reduce the time needed to put
          it in an animation.

       The calculations, slopes, day lighting, etc.
         takes time, especially when the person
         creating the 3D environment has never
         “Designed” any road in their life.
Improvements in the Process
   Corridor Modeling
    Corridor Modeling can create a product worthy
        of rendering and animation in mere
        moments.
    The program is relatively simple to use.
    Creates a 3D surface that can take advantage
        By Level Materials.
    (it should be noted that the Corridor Modeling
        templates do take a sizeable chunk of time
        to initially setup)
Improvements in the Process
   Feature Modeling
    Ability to create smarter cells – feature cells
    Multiple parameter sets for one feature cell

    Set values at time of placement
    Feature cells can be modified

    Easily changed to a different feature cell

    Materials already assigned
Improvements in the Process
   Warehouses and Libraries
       Stock Cells for existing Survey features
       Stock Images
       Stock Buildings
       Stock Cars
