This is a multiple-value field found in TextureCoordinate2. MFVec2f can contain any number of two-dimensional vectors.
[ 0 0, 1.2 3.4, 98.6 -4e1 ]
The MFVec2f field is written as one or more pairs of floating point values separated by whitespace. Again, as with other multiple-valued fields, when more than one value is present, all of the values are enclosed in square brackets and separated by commas.
Example Use
The following code fragment is from NoName_7.wrl.
TextureCoordinate2 {Point [ 0.000 0.000,0.000 0.000,1.000 0.000,...}
