70 A multiple-value field that contains any number of 4x4 matrices.
71 SoMFMatrices are written to file as sets of 16 floating point numbers
73 separated by whitespace. When more than one value is present, all of
74 the values are enclosed in square brackets and separated by commas; for
75 example, two identity matrices might be written as:
76 [ 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1,
78 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 ]

83 void setValue(float a11, float a12, float a13, float a14,
84 float a21, float a22, float a23, float a24,
85 float a31, float a32, float a33, float a34,
86 float a41, float a42, float a43, float a44)
87 Makes this field contain one and only one value, which is the matrix
88 given by the 16 values.
89 static SoType getClassTypeId()
91 virtual void getTypeId() const
92 Returns the type for this class or a particular object of this
93 class.
94 const SbMatrix & operator [](int i) const
96 Returns the i'th value of the field. Indexing past the end of the
97 field (passing in i greater than getNum()) will return garbage.
98 const SbMatrix * getValues(int start) const
100 Returns a pointer into the array of values in the field, starting at
101 index start. The values are read-only; see the startEditing()/fin‐
102 ishEditing() methods for a way of modifying values in place.
103 int find(const SbMatrix & targetValue, SbBool addIfNot‐
105 Found = FALSE)
106 Finds the given value in the array and returns the index of that
107 value in the array. If the value is not found, -1 is returned. If
108 addIfNotFound is set, then targetValue is added to the end of the
109 array (but -1 is still returned).
110 void setValues(int start, int num, const SbMatrix *newVal‐
112 ues)
113 Sets num values starting at index start to the values in newValues.
114 The array will be automatically be made larger to accomodate the new
115 values, if necessary.
116 void set1Value(int index, const SbMatrix & newValue)
118 Sets the index'th value in the array to newValue. The array will be
119 automatically expanded, if necessary.
120 const SbMatrix & operator =(const SbMatrix & newValue)
122 void setValue(const SbMatrix & newValue)
123 Sets the first value in the array to newValue, and deletes the sec‐
124 ond and subsequent values.
125 int operator ==(const SoMFMatrix &f) const
127 int operator !=(const SoMFMatrix &f) const
128 Returns TRUE if all of the values of this field equal (do not equal)
129 those of the given field. If the fields are different types FALSE
130 will always be returned (even if one field is an SoMFFloat with one
131 value of 1.0 and the other is an SoMFInt with a value of 1, for
132 example).
133 SbMatrix * startEditing()
135 void finishEditing()
136 startEditing() returns a pointer to the internally-maintained array
137 that can be modified. The values in the array may be changed, but
138 values cannot be added or removed. It is illegal to call any other
139 editing methods between startEditing() and finishEditing() (e.g.
140 set1Value(), setValue(), etc).
141 Fields, engines or sensors connected to this field and sensors are
143 not notified that this field has changed until finishEditing() is
144 called. Calling finishEditing() always sets the isDefault() flag to
145 FALSE and informs engines and sensors that the field changed, even
146 if none of the values actually were changed.
