3D Polygon Mode

3D-Polygon mode allows you to view models of the cave’s passage walls in stereo mode. In 3D-Polygon mode, the Viewer uses the Left, Right, Up, and Down passage dimensions to create polygons that approximate the appearance of the passage walls. Because the image is stereo, the wall lines appear to be three-dimensional.

Options. You have the option of having the Viewer compensate for missing passage data and placing a centerline down the passage. These options are controlled in the Passage Wall Modeling window.

Performance. 3D-Polygon mode is slower than other modes, because 12 times as many lines are drawn. It is usually best to enable this mode only after you have located the part of the cave you want to examine.
