Intervals for 3d display

Calculating the spherical spline interpolation of the loaded signals to fill the areas between the sensor positions on the head model with interpolated valuesdepends on the currently definied intervals. Therefore intervals must be defined before activating the mapper (see the general intervals page).

Only the slider setting the currently displayed interval/time point remains active and can be used to "scroll" through the active signal (please note that on windows, this is considerably slower than on unix type operating system, because the linear algebra library is currently not well optimized for windows).
