1.1.2 Import continued.

"File / Import => 3D Scanner (Roland .pix)..." : This will load a ".pix" file from a Roland relief-surface digitizer. After a file is selected, the "Import Roland Scanner File" dialog appears. This dialog has four settings.

  • "Insert Scan Heights on Layer" : This determines which layer to insert the height values on.
  • "Insert Mode" : This setting determines how imported surface heights are assigned to the existing sculpture grid.
    Load" - the entire sculpture grid (all layers) is replaced by the imported data. This is similar to loading a sculpture ".vs3" file (from the "File / Load Relief" menu).
    Overwrite" - the imported data overwrites the current sculpture grid only within the XY coverage extents of the imported data.
    Merge" - similar to "Overwrite" mode, except that the imported data heights are added to the existing sculpture grid heights.

  • "Data Sampling %" : This value determines if the data is sub-sampled before conversion to surface heights. If, for example, the import grid measures 1200x1200, and the sampling is 50%, then every other point in the imported grid is skipped (making it, effectively, a 600x600 grid).

  • "Height Scale Factor" : This value is a scale factor that is applied to the scanned heights before loading.

In "Overwrite" and "Merge" insert modes, the placement of the imported data on the existing sculpture grid is determined by the current X and Y Data Coordinate scales. In "Load" insert mode, the X and Y Data Coordinate scales are set to the ranges from the imported file.

When a Roland .pix file is imported, the digitizer points are triangulated and gridded. The size of the grid on which the points are triangulated is determined by the size of the current sculpture grid (in grid points) before the file is imported. The aspect ratio of the final sculpture grid will be adjusted to match the imported surface.
