Hi Jochen, thank you, it helped me with glyph. <div>But still for mappers, I need specify explicitly active scalar range regardless presetting scalar using <span style>SetInputArrayToProcess.</span><div>If I will compute some value for one input, it will not be updated automatically when I change the input.</div>
<div><div><div>I do understand that user can explicitly specify scalar range for mapping via lookup table, but range could be automatically obtain from input array to process scala range .</div><div>But I can not find way how to ensure it for mappers, perhaps it can not be configured like this... ?</div>

<br>
with SetInputArrayToProcess you set what array is to be used for the<br>
scalars, vectors, normals, and color scalars.<br>
<br>
"idx" stands for:<br>
<br>
0 == scalars<br>
1 == vectors<br>
2 == normals<br>
3 == color scalars<br>
<br>
So if you want your array "array1" to specify the color, then idx must be 3<br>
and "array1" of type vtkCharArray (with one component). If you want your<br>
array to specify the point normals e.g, then idx must be 1 and "array1" of<br>
type vtkDouble (with three components).<br>
<br>
(I use SetInputArrayToProcess to tell my glyph3D object which array to use<br>
for orientation and for scaling.)<br>
<br>
Port and Connection I set to 0 always. What it stands for I can only assume<br>
at the moment but won't tell, because it might be wrong. ;-)<br>
<br>
<br>
Hope that helps a little bit.<br>
<br>
with best regards<br>
Jochen<br>
