SoFieldContainer * getContainer() const
A multiple-value field that contains any number of 4x4 matrices.
SoMFMatrices are written to file as sets of 16 floating point numbers 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, two identity matrices might be written as:
[ 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1,
1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 ]
void setValue(float a11, float a12, float
a13, float a14, float a21, float a22, float a23, float a24, float a31, float
a32, float a33, float a34, float a41, float a42, float a43, float a44)
Makes this field contain one and only one value, which is the matrix given by
the 16 values.
static SoType getClassTypeId()
virtual void getTypeId() const
Returns the type for this class or a particular object of this class.
const SbMatrix & 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 SbMatrix * 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 SbMatrix & 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 SbMatrix
*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 SbMatrix &
newValue)
Sets the index'th value in the array to newValue. The array will
be automatically expanded, if necessary.
const SbMatrix & operator =(const SbMatrix &
newValue)
void setValue(const SbMatrix & newValue)
Sets the first value in the array to newValue, and deletes the second
and subsequent values.
int operator ==(const SoMFMatrix &f) const
int operator !=(const SoMFMatrix &f) const
Returns TRUE if all of the values of this field equal (do not equal) those of
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).
SbMatrix * 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.
