Navigation Settings

At the top level of Vapor’s control menu, there is a top-level tab called Navigation, which contains settings that help users identify and visualize where they are in the scene. The Navigation tab is composed of an Annotation tab, and a Viewpoint tab.

Annotations

In the Annotaitons tab, users can add Axis Annotations, Time Annotations, and 3D arrows that indicate which direction the X, Y, and Z axes are oriented in. Users can also control whether they want to render bounding boxes that indicate the extents of their domain.

Animation

Currently in development.

Viewpoint

The Viewpoint tab contains tools that let the user apply global transforms to datasets that they have loaded. This is similar to how individual renderers can be transformed, but in this case the transform applies to all renderers in a dataset.

Projection strings can also be modified if a dataset is georeferenced.

Finally, camera position and direction values are displayed here and may be changed numerically for convenience.

Off Screen Rendering

Sometimes users will want to produce snapshots or animations at a higher resolution than their current display. A rendering can be captured at 4k, or any user-defined resolution by modifying the Framebuffer Settings section of the Viewpoint tab. Simply check the “User Custom Output Size” checkbox, and enter the width and height of the image sequence you would like to capture.
