Objective:
I would like to plot a relief surface from a raster grid in the 3D Viewer. I would also optionally like to drape a different colour image over the relief surface.
Resolution
To display a relief surface in the 3D Viewer in Oasis montaj or Target:
- In the 3D Viewer go to Add to 3D menu > Relief Surface.
- Browse to the Surface relief grid and the Colour image/grid you would like to use > OK.
Those two parameters can be set to the same file if you wish to display a single grid as the relief surface and colour the relief surface with the same grid.
You can also exaggerate the Z scale if you want the changes in elevation to be more noticiable:
- In the 3D Manager, select the relief surface plane.
- Under Plane Options, increase the Scale value.
Note that the values in the Z axis will change by a factor of the value entered for Scale.
