glyphs at cells

The glyphs at cells module is used to place geometric objects (glyphs) at cell center locations. The glyphs can be scaled, rotated and colored based on the input cell data. If the input data is a vector, the glyph can be scaled and rotated to represent the direction and absolute magnitude of the vector field. In a scalar data field, the objects can be scaled based on the magnitude of the scalar. Arrow glyphs are commonly used in vector fields to produce visualizations of the vector field.

Ports

Direction	Name	Type	Description
Input	Input Field	Field	The field to use for placing glyphs.
Input	Input Glyph	Field	The field to use as a glyph.
Input	Z Scale	Number	The factor for vertical scaling.
Output	Output Field	Field	The subset field.
Output	Output Object	Renderable	A renderable object to display.

Properties

Property	Type	Description
Z Scale	Double	The Z Scale is the vertical exaggeration to be applied to the output object.
Allow Run	Boolean	Determines whether the module is allowed to execute.
Execute	Button	Accept all values and places glyphs.

Glyph Settings

Property	Type	Description
Glyph Type	Choice: Generated, Input Glyph, Directed Line	The Glyph Type choice allows the user to select the source for the created glyph. Both the Generated and Directed Line options are created internally. The Input Glyph option requires the Input Glyph port to be connected.
Generated Glyph	Choice: Sphere, Cube, Cone, Cylinder, Polygon, Disk, Point	The Generated Glyph choice allows the user to select the type of glyph that is automatically generated.
Sphere Subdivisions	Integer	The number of subdivisions to use for spheres. Larger numbers create more detailed sphere representations.
Glyph Resolution	Integer	The resolution for generated cone, polygon, cylinder, and disk glyphs.
Include Glyph Data	Boolean	The Include Glyph Data will notify the module to keep data from the Input Glyph field as data for the output.
Primary Axis Factor	Double	The scale factor for the primary axis of the glyph.
Secondary Axis Factor	Double	The scale factor for the secondary axis of the glyph.
Heading Dip	Double	The Heading and Dip values are used to align the glyphs to a constant orientation.
Roll	Double	The roll of the glyph along its primary axis.

Property	Type	Description
Orient By	Choice: Cell Data, Constant	The Orient By option determines how the glyphs are oriented. The Cell Data option uses the specified cell data vector component to define the orientation. The Constant option uses the specified heading, dip and roll for all glyphs.
Cell Orientation Component	Choice	The Cell Orientation Component determines which cell data component is used to rotate and align the glyphs. This data component should be a vector.
Datamap Range	Double	The Datamap range refers to the min and max values that are used by the datamap. This does not change data values from the file.
Size By	Choice: Cell Data, Constant	The Size By option determines how the glyph sizes are determined. The Cell Data option uses the specified cell data component to define the sizes. The Constant option uses a constant size defined in the Glyph Size setting for all glyphs.
Glyph Size	Double	The Glyph Size value is used to scale the glyphs in all directions. The default is automatically computed based on your input data.
Cell Size Component	Choice	The Cell Size Component control determines which cell data component is used to size the glyphs.
Use Log Data	Boolean	The Use Log Data toggle will force the size of the glyph to be based on the log10 of the selected data.
Priority	Choice: Maximum, Minimum	The Priority of the glyph will reverse the scaling so that the smallest sample values have the largest size.
Minimum Scale Factor	Double	The Minimum Scale Factor scales the sample values with the least Priority.
Maximum Scale Factor	Double	The Maximum Scale Factor scales the sample values with the greatest Priority.
Reverse Direction	Boolean	The Reverse Direction option flips the direction of the input glyph by 180 degrees around the Z-axis.
Size For Vector Data	Choice: Use Vector Magnitude, Use Vector Components	The Size for Vector Data allows the user to change the method behavior when sizing by a vector data component.
Magnitude For Zero Length	Double	Magnitude for Zero Length is the vector magnitude at which the glyphs will be zero size. This establishes the minimum level for taking log values since the log of zero is undefined (minus infinity).
Include Center Data	Boolean	The Include Center Data toggle will tell the module to include the center point of each glyph as a cell data component. This allows the user to probe onto the glyph and return its center instead of the position on the outside of the glyph.
