i. Background, Zscale, Animate
The top section of 'Other Options' allows users to customize the background color of the 3D display, and turn on/off the 3D plot axes in the display ('Show/Hide Cube Axes').
Zscale controls the vertical exxageration of the 3D display. By default, an "intelligent" exxageration ratio, Zr, is applied based on the horizontal and vertial extents of the model. An input field is available to allow specifying a user-provided exxageration ratio, Zf (exaggerated elevation = Z*Zf where Z is the original elevation). Applying a Zf of 1.0 allows the user to view the original elevation (no vertical exxageration).
Users can animate (automatically rotate) the 3D display by clicking the 'animate' button. The speed of the rotation of controlled with the 'fps' (frames per second) input field (higher fps means faster rotation, and vice versa).
ii. Surface Offsets
Users can modify the Top and Bottom (Bot) surfaces defining the model (strictly speaking, for the top-most layer; deeper layers can be added from DataNet - see Add DataNet Laters below).
Top Offset and Bot Offset: These text fields are used to raise or lower the top and bottom overlay surfaces by an offset. A positive offset raises the surface; a negative value lowers the surface. By default, very small offset is applied to the top and bottom overlays (+0.5 and -0.5+, respectively).
Opacity sliders are available to control the top and bottom surface layer opacity.
iii. Update Enclosure
Users can add an enclosure (or "curtains") extending from the Top surface to the Bottom surface along the sides of the model. Click the 'UpdateEnclosure' button a first time to add the enclosure. Change the color with the color palatte tool and click the button again to update the enclosure color.
iv. TP Well Size
TP Well Line Width: This controls the thickness of boreholes that are being displayed as vertical lines (applicable when using the TP Well Only option for displaying boreholes).
TP Well Tube Radius: use this text field to increase or decrease the borhole tube (cylinder) radius (applicable when using the Tubing On option for displaying boreholes).
v. Add Water Table
Click this button to add the last simulated water table to the 3D model display, either as a solid-colored surface or as a rendered contour map (contouring options available).
Once added, a drop-down menu is available to select from the contour surface representation, or solid-colored options (solid surface, as points, etc.)
An opacity slider controls the water table surface opacity. A color palette tool is available for choosing the color of solid-colored representations.
Click the checkbox to show the legend for the water table layer.
vi. Add Layer Textures
Click this button to add groundwater flow model layers (i.e., computational layers) as 3D textures in the 3D display.
By default, the layers will be displayed following the main model Display Settings assigned in Domain Attributes window (e.g., contours and vectors and black lines - the default plan view display).
Users can choose to show the layers texturs as:
- solid surface with color picker
- points along the grid with color picker
- wireframe with color picker
- solid surface with wireframe with color picker
Also available are show/hide toggles (for all layers, or for individual layers), and a opacity slider.
vii. Add 3D Point Data
Clicking this button adds 3D point data (i.e., with elevation (Z) information) that was previously loaded into the Scatter Data Spatial analysis Data Table (either currently loaded, or the last loaded onto your MAGNET4WATER account folder).
Several styling options are are available for the user:
- control the number of breaks (sub-divisions) to apply to the data
- control the relative size of the spherical point data
- filter out values below or above a specified minimum or maximum, respectively
- control the specific colors and sizes assigned to values in a certain range/bin
viii. Add Velocity Data
Click this button to add the last simulated groundwater velocity vectors to the 3D model display. Note that the model providing velocity data must have 2 or more computational layers (i.e., the vector data must be 3D).
Users also have the choice to load a saved velocity data file (.uvw extension). After running a groundwater flow model, save tthe velocity data file for uploading to IGW-NET at a later time:
- Run Simulation
- Analysis Tools > Analysis > Post Analysis > Magnet GW
- Download Others >> (expand options)
- Check box next to '3D Velocity' and click 'Apply'. This downloads a .zip folder containing the .uvw velocity file.
Note that files downloaded from a Premium IGW-NET account will be encrypted and, if to be used in an external program, need to be decrypted with the same IGW-NET Premium account: Analysis Tools > Utilities > Decrypt Files
Velocity Draw Options
MaxV controls the maximum length of the velocity vectors (number-of-pixels-long).
CutoffV sets the upper limit of velocities to display. Check the box next to 'Exclude V>Vcut' to hide velocities above the CutoffV value.
Arrow Head Factor: this controls the relative size of the arrow head and arrow shaft within the 3D display. (Increase Arrow Head Factor to make the heads and shafts larger/thicker, and vice versa.)
Skip-X / Skip-Y : The density of velocity vectors is determined by the number grid cells to skip before drawing another velocity vector, both in the X (W-E) and Y (N-S) directions. Use the text boxes provided to control this (see Skip-X and Skip-Y).
Slicing: Check this box create cross-sectional views of the 3D velocity vectors, allowing for analysis of velocities across different planes. Control the slicing in the X-, Y-, and Z- directions using the Slice-I, Slice-J, and Slice-K input fields, respectively (i.e., cell index values along which to create the cross-section(s)). Separate multiple cross-sections in a single direction using a ",".
Blanking: Check this box to remove/obscure ("blank") certain areas of the velocity field, allowing to isolate specific data points or to focus on particular aspects of the model. Control the area to be blanked with the starting indices (Is, Js, Ks) and ending indices (Ie, Je, Ke) in the X-, Y-, and/or Z-direction.
Equal Length : check this box to make all arrows the same length and size, regardless of the groundwater velocity they represent.
ix. Add Particle Data
Click this button (and follow the on-screen prompts) to add the last particle tracking simulation to the 3D model display. Note that you must first have created a .PTLS file on the server (see below).
Users also have the choice to load a saved particle tracking data file (.ptls extension).
CREATING A .PTLS FILE: First, go to Domain Attributes menu (Conceptual Model Tools > DomainAttr), Simulation Settings tab, and check the box next to 'Save PTK results'. After running a groundwater flow model with particle tracking, save the particle tracking results: Other Tools > SaveModel > Latest Particle Results. This downloads the .ptls file from the latest model to your local machine.
Particle Controls include show/hide toggle, color picker, particle sphere size, and an opacity slider.
Pathline Controls include show/hide toggle, and a color picker.
x. Add Well Location
Click this button to add wells from the last simulated groundwater model, or from wells that are currently loaded into the Scatter Data Spatial analysis Data Table.
Well screen elevation information (well screen top elevation, or Zf, and bottom elevation, Zt) should be provided in the Data Table or in the Well Input Options interface (for wells from models). If Zt and Zt are not provided, the well screen will be centered at a distance from the surface that is two-thirds the depth of the aquifer at that location.
xi. Add DataNet Layers
Click this button to add raster (WCS) data layers from a previously constructed DataNET 3DVTK model in the same area as the IGW-NET 3D model. A prompt will ask if you want to load an existing DataNET 3DVTK model, or load the latest from the server.
If no existing DataNET 3DVTK model is available , you can first open a 'Child' (linked) DataNET page and create a new DataNET 3DVTK model:
1 - In IGW-NET, go to: Analysis Tools > Data Explorer > DataNET
2 - after Child DataNET page is loaded, switch to DataNET browser tab and sign into your MAGNET4WATER account.
3 - Open the DataNET Layer Library: Data Layers > Search Library
4 - Find and select raster (WCS) data layers to be used in the 3D model
5 - Go to: 3D Visualization > Cartesian View (X,Y,Z) > Build & Edit Data Layer Model
6 - In Render VTK3D Data plot, select 'Add Data' option and then click 'Render'
After the DataNET 3DVTK model is rendered in DataNET, you can go back to IGW-NET and now click 'Add DataNET Layers' to import the layer(s) from DataNET. (You can also click 'Download Model' in DataNET VTK3D Model interface, and then load this file inside IGW-NET after clicking 'Add DataNET Layers'.)
DataNET Layer Options
Click 'Hide/Show' to toggle the layers on and off in the 3D display.
Click More Options to customize the DataNET Layers:
- Rename or delete the Layer
- Add or remove Layer "Base" (side curtain and min. elevation surface)
- Add/remove and customize the color of an enclosure (side curtain) between 2 DataNET Layers
- Overlay type (solid color, colored elevation map, or local image draping), overlay opacity, and overlay vertial offset.
- Return to default rendering ('Defaut color' button)
If a ELEV (elevation) map overlay is selected, users can check the box next to 'Legend' to add to the 3DVTK legend dissplay.
