MFVec3f: [1,2,3,4,5,6] vs [[1,2,3],[4,5,6]]

[cecilemuller]

Single numeric value are expressed with a simple Number, but how should MFVec3f (and other MFVec types) be represented: a single long Array, or an Array of tiny Arrays ?

[cecilemuller]

While the second is more explicit, the first one (a single long Array) has the benefits:

• same as VRML and X3D
• less nested
• creating a single array has less overhead than creating many tiny ones, especially with large MFVec2f

Also WebGL uses Typed Arrays which is created using a single Array (although that's an implementation detail).
