Glyph

This filter produces a glyph at points or cell centers in an input data set. The glyphs can be oriented and scaled by point or cell attributes of the input dataset.

The Glyph filter generates a glyph (i.e., an arrow, cone, cube, cylinder, line, sphere, or 2D glyph) at each point or cell in the input dataset. The glyphs can be oriented and scaled by the input scalar and vector arrays. If the arrays are point-centered, glyphs are placed at points in the input dataset. If the arrays are cell-centered, glyphs are placed at the center of cells in the input dataset. A transform that applies to the glyph source can be modified to change the shape of the glyph. This filter operates on any type of data set. Its output is a polygonal dataset.

To use this filter, select the Orientation Array to orient the glyphs and the Scale Array to control glyph scaling if desired - each array can be set to 'No array' if orientation or scaling is not desired. When scaling by a 3-element vector array, the Vector Scale Mode can be set to either 'Scale by Magnitude', which scales glyphs according to the vector magnitude, or 'Scale by Components', which treats each component as a separate scaling factor in the corresponding dimension, i.e., the first component is the scaling factor in the x-dimension, the second component scales the y-dimension, and the third component scales the z-dimension. An overall constant Scale Factor is applied following the scaling controlled by other properties of this filter.

The Glyph Mode property controls which points in the input dataset are selected for glyphing since in most cases, glyphing all points in the input dataset can be both performance impeding as well as visually cluttered.
