plume shell :: Earth Volumetric Studio Help

plume shell

The plume shell module creates the external faces of a volumetric subset of a 3D input. The resulting closed volume “shell” generally is used only as a visualization of a plume and would not be used as input for further subsetting or volumetric computations since it is hollow (empty). This module creates a superior visualization of a plume as compared with other modules such as plume passing to external faces and is quicker and more memory efficient.

Info

The plume shell module may be controlled with the driven sequence module.

Ports

Direction	Name	Type	Description
Input	Input Field	Field	A field containing nodal data.
Input	Input Isolevel	Number	The value used for subsetting.
Output	Output Field	Field	A field containing a new unstructured mesh which contains the surfaces which are the external faces of a subset of the input.
Output	Status	String	Text containing the subsetting information.
Output	Plume	Renderable	A renderable object displaying the subsetted plume data.
Output	Output Sequence	Sequence	The generated sequence of states.

Properties

Property	Type	Description
Allow Run	Boolean	The Allow Run toggle will prevent the module from running when unselected.
Execute	Button	Forces the module to run.
Above Direction String	String	When the Subsetting Direction is set to Subset Above Level, the Direction String will use this string as its identifier.
Below Direction String	String	When the Subsetting Direction is set to Subset Below Level, the Direction String will use this string as its identifier.
Status Expression	String	The Status Expression sets the template which is used to generate the status string, and the title for each state of the sequence.
Use Sequencing	Boolean	Turning this on allows the sequences to drive the module instead of the positions.
Include Varying Surface	Boolean	The Include Varying Surface Toggle controls the visibility of the surface having varying data.

Data Processing

Property	Type	Description
Subsetting Component	Choice	The Subsetting Component is the nodal data value to use to subset the input by.
Subsetting Level	Double	The Subsetting Level is used to set the level for subsetting the input field.
Subsetting Direction	Choice: Subset Below level, Subset Above level	The Subsetting Direction choice allows the user to select which range of values to include in the output.
Output Nodal Data	Multi-select	The Output Nodal Data choice allows the user to select the nodal data to include in the output.
Output Cell Data	Multi-select	The Output Cell Data choice allows the user to select the cell data to include in the output.

Sequence Settings

Property	Type	Description
Current State	Choice	The current state to be passed to the script.
State Control	Choice: Slider, Combo Box, List Box	The State Control determines how the user will interact with the created sequence of states.
Allow Cycles	Boolean	Allows the state control to be cycled in CTWS files.
Sequence Generation Properties	Value generator	Generates the list of values for sequencing. Methods: Linear By Step (values from an anchor point at a fixed step size), Linear By Count (a fixed number of evenly-spaced values), User Entries (manually specified values), Per Log Decade (logarithmic spacing with a set number of values per decade).

External Faces

Property	Type	Description
Split Edges	Boolean	Split surfaces when the edge between two neighboring cells is sharp. This improves rendering in most cases.
Constant Surfaces Are Not Split	Boolean	When on, the constant surfaces in the resulting plume are not split. This gives them a smoother appearance in some cases.
Split Edge Angle	Double	The Split Edge Angle is the maximum angle allowed between two adjacent faces before they are disconnected to create visually sharp edges.
