Measure

During surgeries new points are marked off from so-called points of reference with a pair of compasses for the orientation on the globe. Normally the points of reference are located around the pupil. Further points are created through the marking off of spherical distances and offer the possibility to carry out a real surgery in a better way. The SEE++ system offers this possibility by supporting two measurement procedures. On the one hand it is possible to measure any spherical distance on the globe with a virtual pair of compasses. On the other hand you can use the "Triangulation" function to simulate the marking off of two distances for drawing in new points of reference.

To access the measuring function select the entry "Surgeries->Measure" via the Treeview or via the main menu. Afterwards, move the curser over one of the two globes. If you now push the left mouse button, the curser changes its shape and shows the symbol of a pair of compasses.

If you pull the mouse over the globe while still pressing the left mouse button, a spherical line is drawn from the previously clicked point to the current position. At the same time the appropriate distances (spherical and Cartesian) are displayed in the status bar. The measured line can be modified until the left mouse button is released. Afterwards, the measured line is fixed and remains visible until a new measurement is carried out.

Furthermore, the distances in the status bar are displayed as long as the cursor is located inside the 3D-view over the globe used for measurement. By pushing the "ESC" button during the measurement it can be aborted.

As long as "Measure" is selected as the active surgery type, you cannot transpose muscle insertions (neither interactive nor non-graphical)!
