1Overview
This interface is used to create a default model, or send a data layer (raster, vector, or image) to 3D visualization within DataNET's Cartesion View using Visualization Toolkit (VTK) rendering. Users can visualize data layers from DataNET, from outside web data services, or they can upload their own data for 3D visualization.The basic steps to create a 'Default Model' for 3D visualization include:
1) define a "site-scale" area of interest in the map display by drawing an analysis area (Title Toolbar > Draw Analysis Area > 'Rectangle' or 'Polygon').
2) make sure 'Globe View' is toggled off and open the 'Render VTK3D Data' dialog (Title Toolbar > 3D Visualization > Cartesion View...)
3) select the 'Default Model' option, and click 'Render'
4) after a few seconds to minutes of processing a window should pop up with a DataNET VTK3D Model that contains ground surface and bedrock layers, as well as available wells located on the site.
The basic steps to send a DataNET layer to the 3D visualization framework include:
1) select (check) a layer of interest from the Data Layer Library or user Workspace
2) define a "site-scale" area of interest in the map display by drawing an analysis area (Title Toolbar > Draw Analysis Area > 'Rectangle' or 'Polygon').
3a) make sure 'Globe View' is toggled off and open the 'Render VTK3D Data' dialog (Title Toolbar > 3D Visualization > Cartesion View...)
3b) (optional) Create a default model (see above) or load an existing DataNET VTK3D Model ('Uplaod' or 'Last Model') to modify.
4) select the 'Add Data' option and choose a layer name, webservice format (WMS, WFS, or WCS) and specify additional options (or use defaults)
5) click 'Render' and allow the 3D visualization to load (this may take a several seconds or longer, depending on the size/resolution of the data being prepared for 3D visualization).
Additional prompts will appear after clicking 'Render' if using a WCS Service (see more below).
In addition to creating a default model, or sending DataNET data, the 'Render VTK3D Data' dialog 'Capture Map' option can be used to capture the current display and send it to be draped on a specified layer (see the Screen Capture help page for additional details).
To load previous VTK3D models the user can:
1) Load the 'Last Model' from the server (saved to an individual user folder).
2) or 'Load Model' from a local saved *.mgnVTK file.
3) After loading, models can be viewed and edited. Model layers can be added or modified and/or displays can be changed before saving or publishing.
2WMS
Select the WMS Service to prepare an image of the layer for 3D visualization. Note that the image layer will be "draped" on a "texture" that represents the land surface in the 3D visualization (a vertical offset can be applied within the 3D Display interface). The land surface texture can come from a default model, from the global DEM (Digital Elevation Model) data stored on the DataNET Data Center, or, the user can utilize a WCS service layer to prepare a DataNET raster DEM layer and create the texture. (User may also upload their own "texture" from a DEM file; this option is handled in the DataNET VTK3D Model interface.)The Layer Name determines the layer over which the WMS image will be draped.
See the Send Data help page for additional information about WMS data parameters.
3WFS
If you want to render vector data (polygons, lines, or points) for 3D visualization, select the WFS Service. Similar to image 3D visualization, line and polygon vector layers will be "draped" on a "texture" that represents the land surface in the 3D visualization (a vertical offset can be applied within the 3D Display interface). Point data has a special interface that can be used to plots wells (see more on this within the DataNET VTK3D Model help page).In the case of lines and polygons, portions that extended beyond the bounding box will be "trimmed" (or not included) in the 3D display.
The Layer Name determines the layer used to store the vector information.
See the Send Data help page for additional information about WFS data parameters.
4WCS
If you want to prepare raster data (tiled/gridded data layer) for 3D visualization select the WCS Service. If the raster data is a DEM dataset, it can be used to create the "texture" for draping/overlay of additional image/vector layers.The Layer Name determines the layer used to store the raster and elevation texture information.
See the Send Data help page for additional information about WCS data parameters.
After clicking 'Render' for a WCS Service, an initial prompt with ask how you would like to use the data.
"1-Texture (elev. and image)" will create a complete layer, using raster values to create a 3D elevation texture, and also rendering raster values to create an overlaid raster map image with an associated legend.
"2-Elevation only" will create a 3D elevation texture but will not render raster values to create a colored raster map.
"3-Image only" will render raster values to create a colored raster map image with an associated legend, but will need alternativel handling to create an elevation texture for the selected layer.
If option '1' or '2' is selected, a second prompt will ask for a unit multiplier (so that all layers are consistant). This will typically be 1 (e.g., converting meter to meter, or feet to feet), or a conversion factor (e.g., 0.3048 for feet to meter, or 3.28 for meter to feet).
