Multiple-value field containing any number of 4x4 matrices.
A multiple-value field that contains any number of 4x4 matrices.
SoMFMatrix
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 ]
Data copying:
SoMF fields are a kind of "smart container", automatically expanding as necessary to hold the data provided by the application. This is very convenient, but for large blocks of data it may be desireable to avoid making a copy of the application data. The setValuesBuffer() methods allow Open Inventor to directly use an array of values supplied by the application. The application data is not copied. Please see SoMFVec3f
for more information and example code.

setValues
Deprecated.As of Open Inventor 9.3.1, usesetValues(int, com.openinventor.inventor.SbMatrixd[])
instead.Sets num values starting at index start to the values in newValues , an array of double precision values. The array will automatically be made larger to accommodate the new values, if necessary. Note that Open Inventor fields still store only single precision values, not double precision values. The specified values are converted to single precision, then stored. -
find
Calls find(targetValue, false). -
getValues
Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See thestartEditing()
/finishEditing() methods for a way of modifying values in place. -
getValueAt
-
getDirectValues
Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See thestartEditing()
/finishEditing() methods for a way of modifying values in place. -
finishEditing
public void finishEditing()Indicates that batch edits have finished. SeestartEditing()
. -
disableDeleteValues
public void disableDeleteValues()Temporary disable value deleting. -
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 betweenstartEditing()
andfinishEditing()
(e.g.set1Value()
,setValue()
, etc.). Fields, engines or sensors connected to this field and sensors are not notified that this field has changed untilfinishEditing()
is called. CallingfinishEditing()
always sets theisDefault()
flag to false and informs engines and sensors that the field changed, even if none of the values actually were changed. -
setValue
Sets the first value in the array to newValue , a double precision matrix, and deletes the second and subsequent values. Note that Open Inventor fields still store only single precision values, not double precision values. The specified value is converted to single precision, then stored. -
setValues
Sets values starting at index start to the values in the specified array of double precision matrices. The array will automatically be made larger to accommodate the new values, if necessary. Note that Open Inventor fields still store only single precision values, not double precision values. The specified values are converted to single precision, then stored. -
set1Value
Sets the index 'th value in the array to newValue , a double precision matrix. The array will be automatically expanded, if necessary. Note that Open Inventor fields still store only single precision values, not double precision values. The specified value is converted to single precision, then stored. -
setValue
public 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. -
setValues
Sets num values starting at index start to the values. in newValues. The array will automatically be made larger to accommodate the new values, if necessary. In that case, if field's values are stored in an user data array, this array is no more used. -
find
Finds the given targetValue 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). -
set1Value
Sets the index'th value in the array to newValue. The array will be automatically expanded, if necessary. In that case, if field's values are stored in an user data array, this array is no more used. -
equals
-
setValue
Sets the first value in the array to newValue, and deletes. the second and subsequent values. If field's values are stored in an user data array, this array is no more used.
