Readers


The ParaViewGeo readers are probably the most useful plugins for the mining and geoscience industries.
These readers allow importing data from most mining and geological modeling and visualization software into ParaView.

The ParaViewGeo readers supports the following formats:
  • Datamine Files (*.dm)
  • DrillHole SQLite database Files (*.dhd)
  • ESRI Shape Files (*.shp)
  • Geo-Referenced Image (*.jpg, *.tf, *.png)
  • GoCad ASCII Files (*.gp, *.ts, *.pl, *.vs, *.vts, *.vo, *.sg)
  • Minesight Resource Files (*.msr) [No longer available]
  • Map3d Block Data (*.inp)
  • Point Set Files (*.psf)
  • SOT EPS Triangle Files (*.setr)
  • SOT Result Files (*.sof, *.SOT, *.Output, *.File)
  • Vulcan Data Files (*.00t, *.sfg, *.srg, *.bmf, *.isis) (win32 only) [No longer available]
  • Line Network Reader (.lnr)


DataMine Reader

The Datamine Reader allow importing datamine binary files (*.dm) into ParaView. This reader can read DataMine points, perimeter, wireframe, drillholes and blocks.

The properties to import from the DataMine file easily be selected in the user interface:



Point Set File Reader

The Point Set File Reader (*.psf) can read a character separated file containing points and properties. User can specify any separator (for example comma). Each line must contain at least the x,y and z coordinates of a point as well as any number of properties. The file must also contain a header line that helps the user selecting the parameters of the file.

The user interface allow the user to select the fields to use for x, y and z coordinates and the properties to import from the file:





Line Network Reader

The Line Network Reader (*.lnr) allow importing a comma separated file containing lines into ParaView. This reader can render simple lines as well as ventilation networks depending on the selected parameters. The user interface of this reader look as follows:



Arrows: Using  an arrow property allows displaying arrows that shows the direction of the lines (e.g. the direction of the ventilation flow in a ventilation network). The size of the arrows is proportional to the value of the selected Arrow Property on the corresponding line. The size of the arrow can also be scaled using the Arrow Scaler property. The following screenshot show a simple ventilation network where the arrow property was used:


It is also possible to render the lines as tunnels by checking the With Tunnels option. The diameter of the tunnels are proportional to the Arrow Property value and to the specified Arrow Scaler factor:


If the arrow property is set to none, the lines are rendered as simple lines:


Properties can be imported for the lnr file by selecting them in the user interface under the Properties menu:


Another interesting feature of line network reader is that when an Arrow Property is used and some Properties are imported, string properties are created to allow visualizing text on the top of each arrow. For each line, a string copy (label) of each imported property is created and placed on the top of the corresponding arrow:



Using the selection inspector, it is then possible to visualize these labels on the network:
