…and the tolerance level when the sand is coloured white. To adjust these settings, it is easiest to assign a DEM tool as above, and then save the current tool setup by selecting “Save Input Graph” from the “Devices” sub-menu of the Vrui system menu. This creates a text file with the settings for the DEM tool inside. After adjusting the settings, the complete tool setup can be loaded back…

The following is one of those saved ‘input graphs’. Where and what exact syntax must be inserted to adjust the tolerance of the white band (the colour indicating where the sand matches the target DEM)? I want to make the system more tolerant. By default it is impossible for users to ever build a DEM-matched 3D terrain that is completely white (with all blue and red areas eliminated). Please advise:
