The project simulates a flooding, due to a breach in the levee. The breach grows over time because of the amount of water that flows through the breach.
The project shows an area in the San Francisco financial district, created from an I3S Scene Layer and [[Project_Sources|OSM]] data. In this demo we will explore the contents of the 3D model, the used data to generate the model and add a map to analyze the different type of buildings.


===Analyse the project===
===Analyze the project===
# Click on the arrows in the project to get familiar with the boundary conditions in the model.  
# Zoom and click around in the project to inspect the 3D model.  
# Go to the Flooding Overlay (named ''Flooding'') in the Overlay bar. Play the flooding overlay and notice how the water flows for example, around the [[Culvert_(Water_Overlay)|Culvert]]. This overlay shows the [[Surface_last_value_result_type_(Water_Overlay)|Surface last value]] result type. Another interesting result type to study is the [[Surface_last_speed_result_type_(Water_Overlay)|Surface last speed]].  
# To see from which datasets the 3D model is constructed, [[How_to_add_and_remove_an_Overlay|add]] the [[Source_(Overlay)|Source overlay]]. An overlay is a 2D map rendered on top of the 3D visualization. The [[Source_(Overlay)|Source overlay]] highlights the used datasets in a map. First check the I3S San Francisco dataset. Notice most of the buildings in the 3D model are highlighted. This means data from the I3S Scene Layer is used to create these buildings.
# Go to the [[Base_types_result_type_(Water_Overlay)|Base types]] result type, zoom in on the breach location and play the overlay to see how the breach grows over time. The light red area is the active breach area, the dark red area is part of the whole breach area. This is the available space for the active breach to grow depending on the set [[Weather_(Water_Overlay)|simulation time]], the [[Breach_speed_(Water_Overlay)|critical speed]] and the [[Breach_width_(Water_Overlay)|breach width]].
# Uncheck the I3S San Francisco dataset and check the [[Project_Sources|OSM]] dataset. Notice that again almost all buildings are highlighted. This accentuates the effect that the {{software}} uses multiple data sources to create the 3D model. Take a look at the [[Project_Sources|project sources]] page to see all the (open) data we use to generate a new project.
# Take a look at the [[Surface_elevation_result_type_(Water_Overlay)|Surface elevation]] result type. This height data is used for the Water Overlay calculations. If you focus on the breach area, you can clearly see what the breach area does: lowering the terrain height so that water can flood the surface.  
# Click on the [[City_Overlay|default overlay]] to see the default 3D model without a map.  
# Click on the [[Areas|Area menu]] in the Current Situation tab and select the area: ''breach'' in the left panel. In the right panel, select the attributes tab, focus on the attributes and their meaning. Especially the attributes relating to the external area. Since the project area is quite small it does not contain the whole body of water (Ijsselmeer). With no additional settings only the water in the project area would be used as the amount of water which can flow through the breach. Since we would like a more 'realistic' model, the breach area is configured with external area attributes. These attributes enable the use of the Ijsselmeer's whole capacity, without having to create a large project. See the following pages for an explanation of the attributes: [[External_area_(Water_Overlay)|External area]], [[External_surface_level_(Water_Overlay)|External surface level]] and [[External_water_level_(Water_Overlay)|External Water level]].
# Click on the [[Current_Situation|Current situation tab]] on the [[Buildings]] button and select the building that is referred to with the arrow icon. In the right panel, the attributes such as the name of the building and its [[Function|function]] are displayed. Notice that this building has the function office, which is known from the [[Project_Sources|OSM]] dataset.
# Open the flooding wizard and take a look at the settings for the flood event, breach, culvert and output overlays.
# Select the Details tab and scroll through the different attributes and values. These attributes are called [[Function_Value|function values]]. Notice that some attributes have values and some attributes have a value of 0. These values are used in calculation models of [[Grid Overlay]]s.  
# [[How_to_add_and_remove_an_Overlay|Add]] the [[Function Overlay]]. This overlay can highlight one or more functions in the [[3D Visualization]]. When added, the overlay consists of a white map.
# We will now select the function we want to highlight. Therefore click in the right panel on the add button. A new panel pops up.

# The [[Function Overlay]] will now show the buildings with the [[Function|function]] hotel highlighted red.
# Zoom out a bit so that the whole [[project area]] is visible and click on the highlighted red buildings. Notice that a hover panel pops up which also contains some information about the building.

This page provides an overview and explanation about the Demo San Francisco project, available for all users.

About the project

The Demo San Francisco project is available for all users in the trial version and can be found in the main menu under Edit projects. The demo is a working project in which an I3S Scene Layer is used in the new project generation wizard to create the 3D Buildings. This project can serve to further explore the 3D model and its contents.

Demo San Francisco

Project of San Francisco in the Tygron Platform

The project shows an area in the San Francisco financial district, created from an I3S Scene Layer and OSM data. In this demo we will explore the contents of the 3D model, the used data to generate the model and add a map to analyze the different type of buildings.

Analyze the project

  1. Zoom and click around in the project to inspect the 3D model.
  2. To see from which datasets the 3D model is constructed, add the Source overlay. An overlay is a 2D map rendered on top of the 3D visualization. The Source overlay highlights the used datasets in a map. First check the I3S San Francisco dataset. Notice most of the buildings in the 3D model are highlighted. This means data from the I3S Scene Layer is used to create these buildings.
  3. Uncheck the I3S San Francisco dataset and check the OSM dataset. Notice that again almost all buildings are highlighted. This accentuates the effect that the Tygron Platform uses multiple data sources to create the 3D model. Take a look at the project sources page to see all the (open) data we use to generate a new project.
  4. Click on the default overlay to see the default 3D model without a map.
  5. Click on the Current situation tab on the Buildings button and select the building that is referred to with the arrow icon. In the right panel, the attributes such as the name of the building and its function are displayed. Notice that this building has the function office, which is known from the OSM dataset.
  6. Select the Details tab and scroll through the different attributes and values. These attributes are called function values. Notice that some attributes have values and some attributes have a value of 0. These values are used in calculation models of Grid Overlays.
  7. Add the Function Overlay. This overlay can highlight one or more functions in the 3D Visualization. When added, the overlay consists of a white map.
  8. We will now select the function we want to highlight. Therefore click in the right panel on the add button. A new panel pops up.
  9. In the new panel, select the category Leisure and select the Hotel function. Then click on apply.
  10. The Function Overlay will now show the buildings with the function hotel highlighted red.
  11. Zoom out a bit so that the whole project area is visible and click on the highlighted red buildings. Notice that a hover panel pops up which also contains some information about the building.

FAQ

  • How can I change the texture, color or shape of a 3D model?
You can change the look of most 3D models manually in the editor, only Landmarks are fixed in their appearances. You can select the model you would like to change in the project or from the list of present buildings, and change color and texture on the right side of the editor window. You can also change the shape of most models by using the brush functionality.

  • How do I import new 3D models?
You can upload most Geo file formats in the Tygron Platform with the Geo Data Wizard. This way you can let the Tygron Platform generate 3D models based on your imported data values. This can be done starting with generic 3D placeholder buildings up to photo-realistically wrapped buildings (SLPK/ i3s). It is advised to first read the following articles:
-Geo Data
-How to prepare Geo Data
-Custom Geometry
-SLPK
If you already have a specific 3D model you would like to use, the model needs to adhere to the following: Tygron Platform 3D model guidelines (PDF)
  • How do I delete 3D models?
You can select the model to be deleted, by clicking on it in the 3D Visualization or by selecting it from the list of buildings. You can then select to remove the building.

  • Why do some 3D models seem to float in the 3D Visualization?
If imported buildings float, usually the floor/ ground level attribute is not correctly configured in the Geo data file used for the import. When the building is already generated by the Tygron Platform, the most common cause is that the building is close to an edge or other difference in terrain elevation and due to rounding off of grid cells or height sectors the building (partially) floats.
