Highlighting 3D Data

In the 3D view, the highlighting principle remains the same as in the other graphics: once samples are selected, they are consistently highlighted across all graphics using a contrasting colour. However, the 3D environment provides additional, more advanced selection modes accessible from the 3D toolbar.

• Select Above / Below / Left / Right: Select samples on one side of a line.
  • Press and hold the left mouse button, then move the cursor to draw a line.
  • Click again to finalise the line.
  • Samples located above, below, left, or right of the line segment are highlighted depending on the chosen mode.
• Select Rectangle: Select samples within a rectangular area.
  • Press and hold the left mouse button, then drag to draw a rectangle.
  • Click again to finalise the rectangle.
  • All samples inside the rectangle are highlighted.
• Select Inside / Outside Polygon: Select samples based on a custom polygon shape.
  • Click once in the 3D view to begin drawing the polygon.
  • Move the cursor to add vertices.
  • Click again to close the polygon.
  • Depending on the chosen mode, samples inside or outside the polygon are highlighted.

These different modes are compatible with the following shortcuts:

• SHIFT: Add the selected samples to the current selection.
• CTRL: Toggle the selection status of the selected samples.
  • If a sample was already selected, it is removed from the current selection.
  • If a sample was not selected, it is added to the current selection.
