72 A multiple-value field that contains any number of three-dimensional
73 vectors.
74 SoMFVec3fs are written to file as one or more triples of floating point
76 values separated by whitespace.
77 When more than one value is present, all of the values are enclosed in
79 square brackets and separated by commas; for example:
80 [ 0 0 0, 1.2 3.4 5.6, 98.6 -4e1 212 ]
82
86 void setValues(int start, int num, const float xyz[][3])
87 Sets num values starting at index start to the given floating point
88 values. There must be num*3 values in the passed array.
89 void set1Value(int index, float x, float y, float z)
91 void set1Value(int index, const float xyz[3])
92 Set the index'th value to the given floating point values.
93 void setValue(float x, float y, float z)
95 void setValue(const float xyz[3])
96 Sets the field to contain the given value and only the given value
97 (if the array had multiple values before, they are deleted).
98 static SoType getClassTypeId()
100 virtual void getTypeId() const
101 Returns the type for this class or a particular object of this
102 class.
103 const SbVec3f & operator [](int i) const
105 Returns the i'th value of the field. Indexing past the end of the
106 field (passing in i greater than getNum()) will return garbage.
107 const SbVec3f * getValues(int start) const
109 Returns a pointer into the array of values in the field, starting at
110 index start. The values are read-only; see the startEditing()/fin‐
111 ishEditing() methods for a way of modifying values in place.
112 int find(const SbVec3f & targetValue, SbBool addIfNot‐
114 Found = FALSE)
115 Finds the given value in the array and returns the index of that
116 value in the array. If the value is not found, -1 is returned. If
117 addIfNotFound is set, then targetValue is added to the end of the
118 array (but -1 is still returned).
119 void setValues(int start, int num, const SbVec3f *newVal‐
121 ues)
122 Sets num values starting at index start to the values in newValues.
123 The array will be automatically be made larger to accomodate the new
124 values, if necessary.
125 void set1Value(int index, const SbVec3f & newValue)
127 Sets the index'th value in the array to newValue. The array will be
128 automatically expanded, if necessary.
129 const SbVec3f & operator =(const SbVec3f & newValue)
131 void setValue(const SbVec3f & newValue)
132 Sets the first value in the array to newValue, and deletes the sec‐
133 ond and subsequent values.
134 int operator ==(const SoMFVec3f &f) const
136 int operator !=(const SoMFVec3f &f) const
137 Returns TRUE if all of the values of this field equal (do not equal)
138 the given field. If the fields are different types FALSE will always
139 be returned (even if one field is an SoMFFloat with one value of 1.0
140 and the other is an SoMFInt with a value of 1, for example).
141 SbVec3f * startEditing()
143 void finishEditing()
144 startEditing() returns a pointer to the internally-maintained array
145 that can be modified. The values in the array may be changed, but
146 values cannot be added or removed. It is illegal to call any other
147 editing methods between startEditing() and finishEditing() (e.g.
148 set1Value(), setValue(), etc).
149 Fields, engines or sensors connected to this field and sensors are
151 not notified that this field has changed until finishEditing() is
152 called. Calling finishEditing() always sets the isDefault() flag to
153 FALSE and informs engines and sensors that the field changed, even
154 if none of the values actually were changed.
