Addition command line parameters

In addition to the VtkCubeplot commands, the following controls are available within VtkGocadplot. Further, the user can provide on the command line:

vc

Whether (1) or not (0) to view the surface

vn2

Whether (1) or not (0) to view the contour

ncv

Number of contours to display

cc

Whether (1) or not (0) to display color line with its own color

smooth

Whether (1) or not (0) to smooth the surface

nis

Number of laplacian smoothing to perform

CONCLUSIONS AND FUTURE WORK We built both a cube viewer and a surface viewer using the VTK library. To make these viewers more effective research tools, several additions need to be made.

• Geophysical data sets are generally very large. Due to this, SEP has a long background in developing parallel algorithms. One of the next steps in the development of the VtkCubePlot and VtkGocadPlot therefore will be to take advantage of the parallel capabilities of VTK with MPI.
• The ability to interactively slice through the cube rather than requiring slice selection at initiation.
• The ability to pick and store locations within the space.
• The ability to have an interactive list of multiple objects (planes, triangulated surfaces, lines) which can be displayed and/or not displayed interactively.
• The ability to modify objects such as triangulated surfaces.
• The ability to do texture mapping (e.g. velocity surface model with seismic amplitudes overlayed).
• The ability to annotate in the 3-D environment.
• Arbitrary number of cutting planes, and orientation for each plane, currently only 3 cutting planes are supported and only the time plane has arbitrary orientation capabilities.
• Texture mapping of the seismic data over the GOCAD surfaces.
