Display sequence

Cross sections allow you to display many objects simultaneously as intersections or projections, in particular in Cross Section Views. A fixed display sequence is used to generate meaningful displays quickly. From back to front this is:

  • Canvas (the cross section canvas)
  • 3D seismic data or any voxel grids
  • 3D grids (geological and simulation models)
  • Polylines
  • Tri-meshes and 2D grids
  • Wells, logs and markers (only in the Cross Section View, not when displaying a cross section in the 3D View)

Co-visualization of two 3D grid models with seismic backdrop    click to enlarge

In the image above, a 3D grid is shown in solid mode with PHIE as the display property. A second 3D grid is shown in mesh mode. The colored vertical lines are intersections with fault planes from seismic interpretation.

Co-visualization of two different 3D objects is fully supported and one of the most powerful options when using cross sections. For example, with this tool you can QC the resulting 3D grid against the 3D seismic cube. In addition, you can set the transparency of the 3D grid model for easier visual comparisons.

There is one limitation in co-visualization of 3D objects: display of two or more 3D objects of the same type is not yet fully supported in solid mode; in 3D views it will result in display artifacts depending on the viewing angle, in cross-section views only one of the 3D object intersections will be visible. This means that it is not yet possible to display a second seismic volume as transparent overlay to a first one. For comparison of two 3D grid models, we recommend to display one grid in solid and the other in mesh mode, as in the example shown.
