Wireframes
Use the Input tab of the Import Wireframes form, to import a third-party triangulation file and save it as a Micromine wireframe (triangulation database) file.
In addition to importing wireframe data, this function has other uses. For example, you might want to reposition a wireframe by moving it 500m to the East, or apply a grid transformation to the points in a wireframe. In such cases you can Wireframes , process the exported file, and then convert it back to a wireframe using File | Import Wireframes.
Input File Type
Choose the type of Input file from the drop-down list provided:
| Input File Format | Description |
|---|---|
| DXF | Import triangles represented by the 3DFACE command in a DXF file. |
| VULCAN | Import a *.00t triangulation file that has been generated by Maptek's Vulcan software. Compressed file formats (Version 8 and later) and earlier file formats are supported. |
| ASCII | Requires a space separated text file in 3 parts - a header line with the number of points and number of triangles; the coordinates of the points; and the triangles, defined by the point numbers of their vertices. |
| DATAMINE BINARY | A binary triangulation file with a *tr.dm file extension. |
| A corresponding points file *pt.dm must exist in the same location. | |
| DATAMINE TEXT | A text-based triangulation export file with a *tr.* file extension. |
| A corresponding points file *pt.* must exist in the same location. The file will usually have a .txt file extension. | |
| SURPAC | A .dtm file that has been generated by GEMCOM's Surpac software. Surpac DTM files contain three-dimensional images. |
| MICROMINE | When you set the input type to MICROMINE, the function is expecting two files. The first, a triangles file, must contain records with identifiers for the three points in each triangle. The second, a points file, contains the X, Y and Z coordinates for each point. In each case you must define the names of the fields in those files. |
| PLY | 3D polygonal models developed at Stanford University and stored in ASCII file format. A PLY file consists of a header followed by a list of vertices and then a list of polygons. The header specifies how many vertices and polygons are in the file, and also states what properties are associated with each vertex, such as (x,y,z) coordinates, normals and color. The polygon faces are lists of indices within the vertex list. Each face begins with a count of the number of elements in each list. |
| RAW | Adam Technology 3DM Analyst Mine Mapping Suite (*.raw) data files containing geometry and texture coordinates in binary format. |
| OMF | An Open Mining Format project file (binary) with a *.omf file extension. |
Support for trisolations in Surpac DTM files is provided. If you are not importing as a single wireframe, a prefix and a numeric ID are used to uniquely name each trisolation. The import of wireframe attributes in Surpac files is not supported.
File name
Double-click or use the Browse button to navigate to the location of the file containing the triangulated data you want to import.
Triangles and Points files
If you selected MICROMINE as the input file type, enter the type and name of the Micromine file that contains the wireframe triangle definitions. Each record represents a triangle by listing the Point Ids (as defined in the Points file) for the three vertices.
