Hi Virgina,
The OpenSceneGraph-2.3.x dev series has support for Vec3dArray etc.
Its used for loading large scale data such as whole earth shape files
where the precision is required.
There is a big but though, OpenGL hardware is designed around 32bit
floats so has to convert all 64bit floats into 32bit and this
conversion really stuffs up performance, so while Vec3dArray might be
useful for passing large scale data around its not good for rendering.
