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.
