Planes The stereonet program supports planes in a number of different formats, and you can show either the pole or the great circle. You can create planes by clicking twice on the interactive surface of the stereonet. Click and drag outside of the stereonet to instantly see the plane in three dimensions. You can also edit the color and opacity of the plane.

Lines Click on the interactive surface of the stereonet to add a new line, the line will automatically show up in three dimensions. You can change the color and orientation of the line at any time.

Rakes The stereonet program supports rakes through the input of a plane and an orientation (rake) in that plane. The orientation is converted automatically to a line with a trend and plunge, but still remains veiwable as a rake. Create any type of planar geologic fault, as well as fault-bend-folds and blind-thrust faults. Choose the orientation visually and pick the direction and magnitude of the slip vector on the fault plane.

Small Circles The stereonet program supports small circles by inputing the trend and plunge of the cone as well as the radius. The small circle is viewable in three dimensions, and is great for teaching what a small circle is!

Group Data Data can be imported through a simple text box option, where you can copy and paste straight from Excel or any text editor. The stereonet program detects delimitations of tabs, commas, or spaces, so you can use whatever you want! The data can be exported to Excel or other stereonet programs by selecting data in the program and clicking the 'Copy Data' icon; then select the data type you want.

Rose Charts Orientation data can be shown through a rose diagram, and simple statistics on the orientation of the data are calculated in a similar way to Open Stereo.

Histograms Histograms of data orientation can be produced in one click. The plots are (of course) interactive, so you can hover over the binned data to see how many elements are in each bin.

Interactive and Three Dimensional The stereonet is a three dimensional representation of data, the stereonet program in Visible Geology attempts to remind you of this by creating everything in a 3D context. Create an element, then rotate up to see what it means in three dimensions. This is an excellent tool to learn what a stereonet is, and how to use it.

Functions Calculate the intersection of two planes. Calculate the plane that passes through two (or more) lines, rakes, or poles. Easily measure angles by clicking and dragging on the interactive stereonet.

Educational Context This stereonet was built from the ground up with education in mind. The stereonet program acts like a piece of paper but has the added bonus of a third dimension!

Continuing Innovation The stereonet program in Visible Geology is not a finished product, and new features (like contouring!) will be added soon. If you find some bugs, please submit them through the feedback form, and I will fix them right away.
