4D Display page
The 4D Display page of the Variable Properties dialog box offers a range of 4D display settings. The performance of the 4D window is affected by the specifications of your computer and the graphics card and its drivers.

|
Sample visualization size |
Specifies the Sample visualization size method.
A further setting related to sample visualization size is Constrain the minimum size to the sample height. Select this setting to stop samples near the transducer from becoming too small to see. |

|
Ping visualization technique |
Specifies a techniques for Ping visualization. Each technique has an impact on 4D window performance. Disks (low quality) requires less computer resource. Spheres (high quality) requires more computer resource. |

Background |
Specifies the fill for the 4D window background. Backgrounds include:
|

|
Water surface |
Specifies how the water surface is displayed and can provide perspective cues. Water surfaces include:
|

Down sample pings for display |
Select this setting to resample pings (down sample) for the 4D window. The setting can improve the performance of the 4D window when the variable contains a high number of samples per ping. The aims is to improve the visual display of data and this resampling is not meant for data accuracy with respect to calculations. |
4D display limits
Display limits, with respect to Echogram mode, are used to display selected samples. Automatically set or Manually set limits are available. This setting can crudely exclude the display of samples in the ring down zone and/or samples below the acoustic bottom.
