value_type | _v [3] |
General purpose float triple for use as vertices, vectors and normals. Provides general math operations from addition through to cross products. No support yet added for float * Vec3f - is it necessary? Need to define a non-member non-friend operator* etc. Vec3f * float is okay
typedef float osg::Vec3f::value_type |
Data type of vector components.
