hm, OpenSG is normally more geared towards rendering, but of course you
can create meshes dynamically. You can do that either directly by
creating a Geometry and filling its properties (see
Source/System/NodeCores/Drawables/Geometry/Util/OSGSimpleGeometry.{h,cpp}
for examples) or use the GeoBuilder which has an interface similar to
OpenGL immediate mode (see
Source/System/NodeCores/Drawables/Geometry/Base/OSGGeoBuilder.h, both in
the OpenSG 2.0 source tree).
Hope it helps,
Carsten
