Various visualization capabilities of VAPOR GUI can be set in the Visualizer Features panel. This panel is viewed by clicking "Edit Visualizer Features" from the VAPOR GUI Edit menu.
The following are controlled in this panel:
Settings that apply to all visualizers:
- Scene stretching: Specify X, Y and Z scale factors, that will result in a stretching of the scene. This only affects the appearance in the visualization, does not alter the data presented or the flow integration, etc.
- Spin animation: By default spin animation is turned off. Check this and the scene will spin when the user drags and releases the left mouse while moving in the scene. The default can be changed (so that spin animation is on by default) in the User Preferences panel, click Session Defaults.
- Shader reloading: Click this button to cause all the shaders to be reloaded. This is useful for shader developers.
- Visualizer name: Specify a textual name for a visualizer, if the current name is not desired.
- Axis arrows: Check the box "Show X,Y,Z (R,G,B) Arrows". When enabled, red, green and blue arrows are displayed in the X, Y, and Z directions respectively. The arrow location can also be specified, relative to the bottom-lower-left corner of the current region.
- Axis annotation: When enabled, axes are annotated with tic marks and text. The overall font size, number of digits and tic width can be set. For each axis, the minimum and maximum value along the axis (in user coordinates) can be specified, along with the number of tic marks, tic orientation, axis color, number of digits, and tic size along each axis. Axis annotation can be suppressed for an axis by specifying zero tic marks. Under axis annotation properties, a check box "Annotate with Lat/Lon" can be used to specify that horizonatal axis annotation be shown as latitude/longitude degrees (for some georeferenced data). This feature is available for the following map projections: Lambert Conformal Conic, Mercator, longitude/latitude, and cylindrical equidistant.
- Time annotation: When enabled, the current time step can be displayed in the scene, or time stamps, if available, can be displayed. The color, position, and text size for this annotation can be specified.
- (obsolete) terrain surface display: This option is replaced by the capabilities of the Image panel.
- Color bars: Color bars can be displayed for various renderers, based on the transfer function used by those renderers. The position and size of each color bar can be specified, and the text size, number of digits, number of tic marks, and background color can be specified for all color bars. The position and size of each color bar is specified in values between 0 and 1, relative to the horizontal or vertical sizes of the visualizer window. A title or description of each color bar can be displayed below it. At most one color bar can be displayed for each type of renderer (Flow, Contours, 2D Data, Probe, DVR, and Isosurface). A color bar is only displayed for the current (selected) renderer instance, and only when that instance is enabled.
- Data values outside data grid (with layered data) [obsolete; only available prior to VAPOR 2.3]:
- When using layered data (e.g. WRF-ARW data) the data grid may not specify all the values that are in the VAPOR Cartesian data grid; for example atmospheric variables such as QCLOUD are not defined below the terrain. However, when the data is displayed in VAPOR GUI, values below or above the data grid may appear. By default variables are extended above and below the data grid; however this is not always appropriate. For example, variables that are used in flow integration should usually be 0 below the terrain.
- The values above and below the data grid can be set here to any constant value, or to extend up or down.
