This Geometry Nodes setup provides a group node for visualizing vector data between points, edges, or faces in Blender. It allows users to display geometry normals and tangents directly within the node tree for debugging and technical visualization. The node includes parameters for adjusting vector resolution, line thickness, arrowhead dimensions, and overall scale normalization. Users can define custom source positions, select specific destination points, and apply custom filters to control exactly where the visualization vectors are generated.
