4/30/2023 0 Comments Stereonet3d![]() The Wireframe option is the default, and will display the 3D hemisphere with a translucent surface which displays the contours and poles, but allows you to see through the surface inside the hemisphere (e.g., to view planes, vectors). ![]() The 3D Stereonet option has 3 settings: Wireframe, Fill, Hide. It does not affect the display of data on the 3D hemisphere. It also determines the display of the Vector Projection and Plane Projection options. In the 3D Stereonet Plot View, the Stereonet Options > Projection option ( Equal Angle or Equal Area) determines the display of the 2D Stereonet which is displayed in the 3D Stereonet Plot View. However, if you select Display Settings > 3D Display Options > 3D Stereonet > Hide, this will hide the outer surface of the hemisphere, and the display of all planes viewed from outside the sphere, gives an impression of the 3-dimensional rock mass jointing, as you rotate the sphere. In general, the display of Grid Data Planes will fill the entire hemisphere with overlapping planes. The Grid Data Planes checkbox will display the planes of ALL planar data in the main Dips data grid. The Major Planes checkbox will display User Planes and/or Mean Set Planes on the 3D hemisphere. You can plot Major Planes and / or Grid Data Planes. Planes are displayed inside the 3D hemisphere as semi-circular planes which intersect the hemisphere at the plane orientation. The Terzaghi Weighting checkbox will apply the bias correction weighting to vector contours, and mean set planes on the 3D hemisphere. The colour of the 3D vector points can be customized with the Display Settings > Stereonet Colours > Pole Vectors option in the Sidebar.Ĭontours can be displayed on the 3D hemisphere by selecting the Plot Options > Contours checkbox and choosing a contour type: Vectors (pole vector or dip vector), Intersections, or Column (quantitative data column, selected in the Contour Options dialog).The display of the vector points can be toggled on or off by selecting the checkbox for Pole Vector Display or Dip Vector Display in the Sidebar Plot Options.The vector points are displayed as small spheres on the surface of the hemisphere. The 3D sphere can display either pole vectors or dip vectors, according to the currently selected Pole Vector Mode / Dip Vector Mode. 3D plotting and display options are available in the Sidebar as described below.The North direction is indicated by an arrow on the circumference. The 3D plot can be rotated for viewing at any angle by clicking and dragging with the left mouse button.Select the 3D Stereonet Preset option from the toolbar or the View menu.This is a valuable educational and analysis tool which provides an alternative to the traditional 2-dimensional stereonet.ģD hemisphere showing contours, poles, mean planes, and 2D equal area projection This allows you to see the raw orientation data, before projection onto 2D. The 3D hemisphere can be rotated for viewing at any angle. The 3D Stereonet allows you to plot poles, planes and contours on a 3D hemisphere view, which is the basis for generating a 2D stereonet. ![]() Traverse Information Import Rules and Limitations.
