Image Renderer

Description

The Image Renderer displays a georeferenced image that is automatically reprojected and fit to the user’s data, as long as the data contains georeference metadata.

The Image Renderer may be offset by a height variable to show bathymetry or mountainous terrain.

Basic Controls

This renderer contains a subset of Vapor’s standard renderer controls: the Variables, Appearance, and Geometry tabs.

The Image Renderer’s Appearance tab does not contain a transfer function since it is not rendering any variable with color or opacity.

Specialized Controls

Georeferenced images may be selected for rendering in the Appearance tab. Vapor comes bundled with two georeferenced image products: NaturalEarth, and BigBlueMarble.

If an image contains transparency, this transparency can be toggled with the Ignore transparency checkbox. Vapor’s BigBlueMarble contains transparency over its ocean regions so that sub-surface ocean models may be viewed alongside land masses.
