Multiple Viewer Index nodes

[Durman]

Problem statement

It seems multiple nodes does not work correctly with multiple objects.

the matrix is only applied to the first object in the second idxviewer.

i am reluctant to call it a bug, because i intentionally coded it this way. I'll agree that maybe it is unexpected/inconsistent behaviour

sverchok/nodes/viz/viewer_idx28.py

Lines 197 to 201 in 78ef71e

	# ensure they are Matrix() multiplied
	for obj_index, verts in enumerate(input_stream):
	if obj_index < len(geom.matrix):
	matrix = geom.matrix[obj_index]
	input_stream[obj_index] = [matrix @ v for v in verts]

I see. Then it is vectorization problem (similar to this #3908). What was the intention to code it in this way?

I think we have convention of auto matching objects number inside nodes.

What was the intention to code it in this way?

whatever the reason was, I think it makes sense to change the behaviour to conform to current vectorization practices - i am happy to change it.

[zeffii]

same can be done for edges/faces -but- i like a debug tool to be as minimal as possible, inventing data is not minimal. The primary use case is for single object input, constructing geometry from scratch.

it's tempting to revise the node further

• text alignment
• quick-scale font
• index range selection
• element selection (as per Custom text on edges and faces (Viewer Index) #4566 )
