12.6.1. Volume Rendering: Geometry Tab

The Geometry tab has the following settings:

Domains

Where the Volume Rendering will be calculated.

Variable

The name of the variable to be used in determining the transparency of the object.

Range

Range enables you to plot using the global, local, or a user specified range of a variable. The range affects the variation of transparency used when plotting the object in the viewer.

  • The Global range option uses the variable values from the results in all domains (regardless of the domains selected on the Geometry tab) and all time steps (when applicable) to determine the transparent and opaque values.

  • The Local range option uses only the variable values on the current object at the current time step to set the transparent and opaque range values. This option is useful to use the full transparency range on an object.

  • The User Specified range option enables you to specify your own transparent and opaque values. You can use this to concentrate the full transparency range into a specific variable range.

Boundary Data

You can specify the use of Hybrid or Conservative values. For help on the use of Hybrid or Conservative values, see Hybrid and Conservative Variable Values in the CFX Reference Guide.

Transparency Scale

Sets calculation of the object transparency with either a Linear or Logarithmic scale. By default, the scale is Linear.

Transparency Map

The name of the color map to use when rendering the transparency of the object.


Note:  You can create your own transparency map by clicking the map editor icon  . It is possible to invert the transparency gradient (making larger data values more transparent), but using an inverted transparency gradient with a user-specified range of values may cause "holes" to appear in the plot.


Resolution

The number of plane cuts per axis. The larger the number of plane cuts, the finer the resolution in the volume rendering.

Transparency Factor

The factor applied to the overall transparency of the plot. Values can range from 0 (fully opaque) to 1 (fully transparent).
