<h3>B.5: 3D Spectrogram Controls</h3>
The 3D Spectrogram controls are only visible when the 3D Spectrogram is being displayed.
<h4>B.5.1: Style</h4>
This dropdown determines how the 3D Spectrogram data is rendered.
- Points: The data are rendeded as points.
- Lines: The data points are connected by lines.
- Solid: The data are rendeded as a solid surface with constant illumination.
- Outline: The data are rendered as a solid surface with outlines of the polygons highlighted.
- Shaded: The data are rendeder as a solid surface with a combination of ambient and diffuse lighting. This requires OpenGL 3.3 or greater.
<h4>B.5.2: Color Map</h4>
This dropdown allows the selection of a number of pre-defined color maps that are used for rendering the 3D Spectrogram.
'Angel' is the default SDRangel color map.
<h2>3D Spectrogram Controls</h2>
The 3D Spectrogram view can be controlled by mouse/trackpad:
- Left button: Rotate
- Middle button: Pan
- Right button: Scale Z axis (power)
- Wheel/pinch: Zoom
Or keyboard:
- Arrow: Rotate
- CTRL Arrow: Pan
- '+'/'-': Zoom
- CTRL '+'/'-': Scale Z axis (power)
- 'r': Reset view to default
- 'f': Flat view (top down)

- _Graphics_: opens a dialog to choose graphics options.
- _Logging_: opens a dialog to choose logging options. See "Logging" paragraph next for details
- _FFT_: opens a dialog to run the `fftwf-wisdom` utility with a choice of direct and possibly reverse FFT sizes. It produces a so called wisdom file `fftw-wisdom` that speeds up FFT allocations. It is created at a default location and will be used at next invocations of SDRangel. See "FFT" paragraph next for details.
- _My Position_: opens a dialog to enter your station ("My Position") coordinates in decimal degrees with north latitudes positive and east longitudes positive. This is used whenever positional data is to be displayed (APRS, DPRS, ...). For it now only works with D-Star $$CRC frames. See [DSD demod plugin](../plugins/channelrx/demoddsd/readme.md) for details on how to decode Digital Voice modes.

When clicking on the Graphics submenu a dialog opens for setting graphics options.

<h4>2.4.1</h4>
Multisampling (MSAA) determines whether multisampling anti-aliasing is used to removed the jagged edges of lines when rendering 2D and 3D spectra.
The higher the number of samples chosen, the better quality the anti-aliasing will be, but higher values require more GPU processing and memory.
Changing this option will only take effect when spectrum windows are recreated (not just hidden then made visible again), so in some cases it
may be necessary to restart SDRangel to see the difference.
