ShowFieldGlyphs

This module visualizes the data that makes up a Field. When possible and selected, the glyph takes its color from the data values that permeate the field.

Ports

This module has 6 input ports, 3 field inputs and 3 color map inputs. The only required port is the first field input port because that holds the data that is visualized. By default, ports will be set to primary input.

Secondary and Tertiary Ports
The secondary and tertiary ports can be used to scale vector parameters like width. Ex: When rendering vectors as a cone the orientation and length of the cone are determined by the primary field, but the secondary field can be used to change the radius of the cone.

They can also be used to assign colors based on data besides the primary field. Ex: If you want to render scalars in RGB, you can give a secondary input of a vector or tensor and set the coloring to RGB Conversion through the secondary input.

Color

By default, glyphs is displayed using the default color, which is editable from the GUI.

Color Map
If there is a color map and field attached to the selected input port, then the data in the selected field input is used as an index into the corresponding color map, and the glyph is rendered with the color at that point.

Type	Description
Scalar	Uses scalar value as index
Vector	Uses vector’s length as index
Tensor	Uses the vector magnitude of the 3 eigenvalues as the index

RGB Color Conversion
If there is a field attached to the selected input port, then the data in the selected field is converted into a color. The RGB color components are generated by the absolute value of vector x, y, z components:

   (R = |x|, G = |y|, B = |z|)

Type	Description
Scalar	Creates gray-scale mapping
Vector	Normalized vector creates RGB colors
Tensor	Principle eigenvector(normalized) creates RGB colors
