This page outlines the process for creating a 3D animation using QGIS. QGIS version 3.34.1 has been used for this example.

<li> Open the 3D Map View to view the 3D depth results and terrain.
<br>
<br>
'''Note:''' The "2D Contour Color Ramp Shader" rendering style option sets the symbology of the results to replicate the symbology in the current 2D map view. For this example, the depth results in the 3D map view reflects the depth map output symbology.

==Create a 3D Animation==
A 3D animation is based on a set of keyframes (camera positions at certain times). To create an animation:
To create an animation, refer to instructions published on the QGIS website: [https://docs.qgis.org/3.34/en/docs/user_manual/map_views/3d_map_view.html#creating-an-animation Creating an animation]. ▼

<li>In the 3D Map View, toggle on the 'Animations' tool [[File: QGIS_3D_Animation_animation_button_01.png|20px]]. This opens the following widget:<br>
<br>
[[File: QGIS_3D_Animation_player_widget_01.png]]<br>
<br>
<li>Click 'Add Keyframe' [[File: QGIS_3D_Animation_add_keyframe_button_01.png]] and enter a time in seconds. This will add the time to the Keyframe dropdown box:<br>
<br>
[[File: QGIS_3D_Animation_keyframe_dropdown_box_01.png]]<br>
<br>
<li>Use the navigation tools to move the 3D map to the desired position for the current keyframe time.
<li>Repeat steps 2 and 3 to add as many keyframes as required. QGIS will generate scenes using the 3D map's positions/rotations at set times, and it will interpolate them in between the keyframes.
<li>To preview the animation, click 'Play', or use the timeslider.
