DESCRIPTION
A multiple-value field that contains any number of three-dimensional vectors.

SoMFVec3fs are written to file as one or more triples of floating point values separated by whitespace.

When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:
[ 0 0 0, 1.2 3.4 5.6, 98.6 -4e1 212 ]

METHODS
void
setValues(int start, int num, const float xyz[][3])
Sets num values starting at index start to the given floating point values. There must be num*3 values in the passed array.

void
set1Value(int index, float x, float y, float z)
void
set1Value(int index, const float xyz[3])
Set the index'th value to the given floating point values.

void
setValue(float x, float y, float z)
void
setValue(const float xyz[3])
Sets the field to contain the given value and only the given value (if the array had multiple values before, they are deleted).

static SoType
getClassTypeId()
virtual void
getTypeId() const
Returns the type for this class or a particular object of this class.

const SbVec3f &
operator [](int i) const
Returns the i'th value of the field. Indexing past the end of the field (passing in i greater than getNum()) will return garbage.

const SbVec3f *
getValues(int start) const
Returns a pointer into the array of values in the field, starting at index start. The values are read-only; see the startEditing()/finishEditing() methods for a way of modifying values in place.

int
find(const SbVec3f & targetValue, SbBool addIfNotFound = FALSE)
Finds the given value in the array and returns the index of that value in the array. If the value is not found, -1 is returned. If addIfNotFound is set, then targetValue is added to the end of the array (but -1 is still returned).

void
setValues(int start, int num, const SbVec3f *newValues)
Sets num values starting at index start to the values in newValues. The array will be automatically be made larger to accomodate the new values, if necessary.

void
set1Value(int index, const SbVec3f & newValue)
Sets the index'th value in the array to newValue. The array will be automatically expanded, if necessary.

const SbVec3f &
operator =(const SbVec3f & newValue)
void
setValue(const SbVec3f & newValue)
Sets the first value in the array to newValue, and deletes the second and subsequent values.

int
operator ==(const SoMFVec3f &f) const
int
operator !=(const SoMFVec3f &f) const
Returns TRUE if all of the values of this field equal (do not equal) the given field. If the fields are different types FALSE will always be returned (even if one field is an SoMFFloat with one value of 1.0 and the other is an SoMFInt with a value of 1, for example).

SbVec3f *
startEditing()
void
finishEditing()
startEditing() returns a pointer to the internally-maintained array that can be modified. The values in the array may be changed, but values cannot be added or removed. It is illegal to call any other editing methods between startEditing() and finishEditing() (e.g. set1Value(), setValue(), etc).

Fields, engines or sensors connected to this field and sensors are not notified that this field has changed until finishEditing() is called. Calling finishEditing() always sets the isDefault() flag to FALSE and informs engines and sensors that the field changed, even if none of the values actually were changed.
