Viewer Index+¶
Functionality¶
This node’s primary purpose is for display the index information of geometry and topology, it will draw the indices of Vertices
, Edges
, and Faces
Vertex indices are drawn on the locations of the vertices
Edge indices are drawn on midpoint of the Edge
Face indices are drawn at the average location of the Vertices associated with the face.
Additionally
the input geometry can be transformed using the Matrix socket.
the Node can draw arbitrary (non renderable) text into the 3dview at the location of incoming verts, edges and faces. If incoming data is shorter than number of elements the last element will be displayed on rest elements.
Because it can be difficult to read indices when there are many geometric elements visible there is an option to draw a small background under the text element.
Parameters¶
- Activate
Enabling the node.
- Draw background
Hide background around text.
- Draw bface
(using the Ghost icon in the Node UI) if you attach verts + faces, you can also hide backfacing indices from being displayed. Adding the faces information gives the node enough information to detect what can be seen directly by the viewport “eye” location.
- Draw object index
(available from N Panel) the Node can display the Object index associated with the element ( the first object, first index will be drawn as
0: 0
)
