This application allows the achievement of the stereographic projection for one or so poles of faces given by their respective spherical coordinates f, the arch that measures the separation from the North pole of the projection sphere and q, the arch that measures the separation from one reference meridian, arbitrary but here conveniently chosen.
Mode of use
Initially enter the value of the arch f in degrees, from 0o to 360o, by clicking on the numbered buttons sequentially. When the angle on the respective display coincides with the desired value, click on button a. This will store the value. If there is a typing error, click in the circle at the left and type the correct number (attention, this will delete all numbers previously stored).
Following enter the value of the arch q in degrees, as described in the previous paragraph.
To send the stored coordinates to the stereographic projection diagram, click on button b. Now enter the coordinates of the next pole, respecting the limit.
To start a new job, click on the circle.
Limit
Up to 99 angles f and 99 angles q can be entered to represent the same number of poles of faces in stereographic projection with this application. If the limit is not respected, the panel will change red. In this case, just click in the circle to clean and execute new job.
Simple suggestion
Enter the spherical coordinates inherent to the cube faces in two orientation twisted of 45o.
