for visualizing the normals of a geometry, there are two functions in OSGGeoFunctions.h: calcVertexNormalsGeo(Geometry *geo, Real32 length); calcFaceNormalsGeo (Geometry *geo, Real32 length); In general you'd have to build a geometry that shows the lines, the tutorial on the wiki (<http://opensg.vrsource.org/trac/wiki/Tutorial>) has a chapter on those and the files Source/System/NodeCores/Drawables/Geometry/Util/OSGSimpleGeometry.{h,cpp} have examples.
