Convert Voxels to Vector Voxel

Use the Voxels to Vector Voxel option (geogxnet.dll(Geosoft.GX.VoxUtils.ConvertVoxelsToVectorVoxel;Run)*) from the Voxel > Conversions menu, to assemble 3 voxel files into a Vector Voxel model.

Voxels to Vector Voxel dialog options

[X|Y|Z] or [U|V|W] voxel	The 3 Geosoft input voxel files to be assembled into a vector voxel (see Application Notes). Script Parameters: X/U -> ConvertVoxelsToVectorVoxel.INPUTVOXELX Y/V -> ConvertVoxelsToVectorVoxel.INPUTVOXELY Z/W-> ConvertVoxelsToVectorVoxel.INPUTVOXELZ
Cartesian	The above voxel files are the mutually orthogonal X, Y & Z components of the field in the standard Cartesian coordinate system. This is the default. If selected, the Inclination & Declination fields are disabled. Script Parameter: ConvertVoxelsToVectorVoxel.CARTESIANROTATED (0:Cartesian)
Rotated	The above voxel files are the U, V, W components of the rotated coordinate system, defined by an inclination and declination. If selected, the Inclination & Declination fields are enabled. Script Parameter: ConvertVoxelsToVectorVoxel.CARTESIANROTATED (1:Rotated)
Inclination (degrees)	The direction relative to the horizontal plane. Script Parameter: ConvertVoxelsToVectorVoxel.INC
Declination (degrees)	The azimuth direction on the horizontal plane. Script Parameter: ConvertVoxelsToVectorVoxel.DEC
Output vector voxel	The output Geosoft vector voxel file Script Parameter: ConvertVoxelsToVectorVoxel.OUTPUTVECTORVOXEL

Application Notes

A vector voxel is a voxel model represented by 3 scalar values at each voxel point. These values define the 3 scalar components of a vector. A vector voxel model is displayed in the 3D viewer with directional arrows; the size and colour of which are indicative of the magnitude.

A vector voxel can be assembled from its 3 components in the standard Cartesian coordinate system, or a rotated coordinate system. In the standard Cartesian coordinate system, the scalar components are denoted as the X, Y, & Z component voxels. The X component is analogous to Easting, the Y component analogous to Northing and the Z component direction is upwards positive. In the rotated coordinate system, the projected components are denoted as U, V, & W. The U component is positive in the direction of the specified inclination and declination, the V and W components are perpendicular to each other and to U.

If a 3D Viewer is open when running the conversion, the output vector voxel will be displayed in the 3D Viewer window. Otherwise, the output voxel will be displayed into a new Voxel Viewer window. If the output voxel does not display, open the 'Advanced Settings' dialog (Project > Settings > Advanced) and under the Voxel Settings section, check if the 'Display Created Voxels' option is set to "True".
