5.1, Table 5.1

Replace Table 5.1 with the following:

Insert the following new field types after 5.8 and renumber the remaining subclauses:

5.9 SFMatrix3d and MFMatrix3d

The SFMatrix3d field specifies a 3×3 matrix of double precision float elements. An MFMatrix3d field specifies zero or more 3×3 double precision matrices. Each SFMatrix3d field is encoded as nine ISO C double-precision floating point values (see ISO/IEC 9899) separated by whitespace. The first three double precision floating point numbers represent the top row of the matrix. The second three double precision floating point numbers represent second row of the matrix. The last three double precision floating point numbers represent the bottom row of the matrix.

EXAMPLE

5.10 SFMatrix3f and MFMatrix3f

The SFMatrix3d field specifies a 3×3 matrix of single precision float values. An MFMatrix3d field specifies zero or more 3×3 single precision matrices. Each SFMatrix3d field is encoded as nine ISO C single precision floating point values (see ISO/IEC 9899) separated by whitespace. The first three single precision floating point numbers represent the top row of the matrix. The second three single precision floating point numbers represent second row of the matrix. The last three single precision floating point numbers represent the bottom row of the matrix.

EXAMPLE

5.11 SFMatrix4d and MFMatrix4d

The SFMatrix3d field specifies a 4×4 matrix of double precision float elements. An MFMatrix3d field specifies zero or more 4×4 double precision matrices. Each SFMatrix3d field is encoded as sixteen ISO C double-precision floating point values (see ISO/IEC 9899) separated by whitespace. The first four double precision floating point numbers represent the top row of the matrix. The second four double precision floating point numbers represent second row of the matrix. The third four double precision floating point numbers represent the third row of the matrix. The last four double precision floating point numbers represent the bottom row of the matrix.

EXAMPLE

5.12 SFMatrix4f and MFMatrix4f

The SFMatrix3d field specifies a 4×4 matrix of single precision float values. An MFMatrix3d field specifies zero or more 4×4 single precision matrices. Each SFMatrix3d field is encoded as sixteen ISO C single precision floating point values (see ISO/IEC 9899) separated by whitespace. The first four single precision floating point numbers represent the top row of the matrix. The second four single precision floating point numbers represent second row of the matrix. The third four single precision floating point numbers represent the third row of the matrix. The last four single precision floating point numbers represent the bottom row of the matrix.

EXAMPLE

5.16

Append the following new field types as the last two field types:

5.21 SFVec4d and MFVec4d

The SFVec4d field specifies a four-dimensional (4D) double precision vector (or a three-dimensional homogeneous vector). An MFVec4d field specifies zero or more 4D double precision vectors. SFVec4d's and MFVec4d's are encoded as four ISO C floating point values (see ISO/IEC 9899) separated by whitespace.

EXAMPLE

<field name="point="
type="MFVec4d"
value="1.000000000001 42 666.35357878 0.5748998763, 7 94 0.100000000007 1.11111111111"/>

is an MFVec4d field, point, defining a double precision vector value.

5.22 SFVec4f and MFVec4f

The SFVec4f field specifies a four-dimensional (4D) single precision vector (or a three-dimensional homogeneous vector). An MFVec4f field specifies zero or more 4D single precision vectors. SFVec4f's and MFVec4f's are encoded as four ISO C floating point values (see ISO/IEC 9899) separated by whitespace.

EXAMPLE

<field name="point="
type="MFVec4f"
value="1 42 666 13.5, 7 -94.7 0 3.678"/>

is an MFVec4d field, point, defining a single precision vector value.
