Hi Antoine,
I'm not sure where you might have got the idea that Vec4 uses doubles,
the typedef in include/osg/Vec4 is:
typedef Vec4f Vec4;
And Vec4f most definitely uses floats.
All of Vec2, Vec3 and Vec4 all are typedef'd to Vec2f, Vec3f and Vec4f
respectively as OpenGL hardware has up till very recently only been
capable of handling floats.
Robert.
