I have a class Vector. The first members I have typed into the class:

Scalar x;
Scalar y;
Scalar z;

Scalar is a typedef for double. There are several other members (data and code) I examined this class at runtime and discovered that the doubles are not packed tightly in memory, ie: &x+sizeof(Scalar) != &y. This expression evaluates to true. Is there a way I can ensure they are adjacent in memory? I want to be able to use the data in calls to OpenGL array routines, but would rather avoid converting each Vector to a struct PackedVert3{Scalar x,y,x;}
