read evs field read evs field reads a dataset from the primary and legacy file formats created by write evs field. .EF2: The only Lossless format for models created in 2024 and later versions .eff ASCII format, best if you want to be able to open the file in an editor or print it. For a description of the .EFF file formats click here. .efz GNU Zip compressed ASCII, same as .eff but in a zip archive .efb binary compressed format, the smallest & fastest format due to its binary form Output Quality: An important feature of read evs field is the ability to specify two separate files which correspond to High Quality (e.g. fine grids) and Low Quality (e.g. coarse grids a.k.a. fast).
import vtk import vtk reads a dataset from any of the following 9 VTK file formats. Please note that VTK’s file formats do not include coordinate units information, not analyte units. There is a parameter which allows you to specify coordinate units (meters are the default). vtk: legacy format vtr: Rectilinear grids vtp: Polygons (surfaces) vts: Structured grids vtu: Unstructured grids pvtp: Partitioned Polygons (surfaces) pvtr: Partitioned Rectilinear grids pvts: Partitioned Structured grids pvtu: Partitioned Unstructured grids Module Output Ports
import cad General Module Function The import cad module will read the following versions of CAD files: AutoCAD DWG and DXF files through AutoCAD 2021 (version 24.0) Bentley Microstation DGN files through Version 8. This module provides the user with the capability to integrate site plans, buildings, and other 2D or 3D features into the EVS visualization, to provide a frame of reference for understanding the three dimensional relationships between the site features, and characteristics of geologic, hydrologic, and chemical features. The drawing entities are treated as three dimensional objects, which provides the user with a lot of flexibility in the placement of CAD objects in relation to EVS objects in the visualization. The project onto surface and geologic_surfmap modules allow the user to drape CAD line-type entities (not 3D-Faces) onto three dimensional surfaces.
import vector gis The import vector gis module reads the following vector file formats: ESRI Shapefile (.shp); Arc/Info E00 (ASCII) Coverage (.e00); Atlas BNA file (.bna); GeoConcept text export (.gxt); GMT ASCII Vectors (.gmt); and the MapInfo TAB (.tab) format. Module Input Ports Z Scale [Number] Accepts Z Scale (vertical exaggeration) from other modules Module Output Ports Z Scale [Number] Outputs Z Scale (vertical exaggeration) to other modules Output [Field] Outputs the GIS data. Output Object [Renderable]: Outputs to the viewer Properties and Parameters
import raster as horizon The import raster as horizon module reads several different raster format files in EVS Geology format. These formats include DEMs, Surfer grid files, Mr. Sid files, ADF files, etc.. Multiple import raster as horizon modules can be combined with combine horizons into a 3D geologic model. Alternatively, a single file can be displayed as a surface (with surfaces from horizons) or you can export its coordinates (with export nodes) to use the values in a GMF file.
buildings The buildings module reads C Tech’s .BLDG file and creates various 3D objects (boxes, cylinders, wedge-shapes for roofs, simple houses etc.), and provides a means for scaling the objects and/or placing the objects at user specified locations. The objects are displayed based on x, y & z coordinates supplied by the user in a .bldg file, with additional scaling option controls on the buildings user interface.
read_lines The read_lines module is used to visualize a series of points with data connected by lines. read_lines accepts three different file formats, with the APDV file format the lines are connected by boring ID, with the ELF (EVS Line File) format each line is made by defining the points that make up the line, and with the SAD (Strike and Dip) file format, there is a choice to connect each sample by ID or by Data Value.
read strike and dip General Module Function The read strike and dip module is used to visualize sampled locations. It places a disk, oriented by strike and dip, at each sample location. Each disk is probable and can be colored by a picked color, by Id, or by data value. If an ID is present, such as a boring ID, then there is an option to place tubes between connected disks, or those disks with similar Id’s.
read glyph read glyph replaces the Glyphs sub-library that was in the tools library. It reads glyphs saved in any of the three primary EVS field file formats and allows you to modify the shape and orientation of the glyph to allow it to be used in various modules that emply glyphs in slightly different ways. These include glyphs at nodes, place_glyph,drive_glyphs, advector, post_samples, etc. Most modules EXCEPT post_samples will use the glyphs without chaning the default alignment. The supported file formats are:
