Instructions

On the Model menu, point to Triangle Attributes, then click Colour by Attribute.

Follow these steps:

1. Choose how you want to select the triangulations:

   • Apply to triangulations loaded in Vulcan - Apply the colours to all triangulations that are currently loaded in Vulcan.

   • Apply to triangulations found in selection file - Apply the colours only to triangulations that are listed in the selection file and that are in your current working directory.

     1. Select the Alternate tri folder check box and select a directory name from the drop-down list or click Browse to select a different folder.

   • Apply to selected triangulations - Apply the colours only to triangulations that you have specified in the Path column.

     1. Select the desired triangulation file(s) from the file list, which shows all available files in the current working directory. You can select files from a different location by clicking Browse..., or use the buttons to go to the last folder visited, go up one level, or change the way details are viewed in the panel, respectively.

        To highlight multiple list items at once, use the left mouse option in combination with the Shiftkey (this is for items that are adjacent in the list; for non-adjacent items, use the Ctrlkey and the left mouse option).

        Tip

        To filter file names using wildcard characters, type in a pattern in the Wildcard field using * for a multi-character and ? for a single-character wildcard.

        If you would like to use a previously created selection file (.sel) containing a list of desired triangulation files to load, choose Selection Files (*.sel) from the Files of type drop-down list.
