Class SoMFRotation

  • public class SoMFRotation
extends SoMField
    Multiple-value field containing any number of SbRotations. A multiple-value field that contains any number of SbRotations.

    SoMFRotations are written to file as one or more sets of four floating point values. Each set of 4 values is an axis of rotation followed by the amount of right-handed rotation about that axis, in radians.

    When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example: 

       [ 1 0 0 0, -.707 -.707 0 1.57 ]

    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

        public void setValues​(int start,
                      int num,
                      float[] q)
        Deprecated.
        As of Open Inventor 9.3.1, use setValues(int, float[]) instead.
        Sets values from an array of arrays of 4 floats.

      • setValues

        public void setValues​(int start,
                      int num,
                      SbRotationd[] rd)
        Deprecated.
        As of Open Inventor 9.3.1, use setValues(int, com.openinventor.inventor.SbRotationd[]) instead.
        Sets num values starting at index start to the values in newValues , an array of double precision rotations. 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

        public int find​(SbRotation targetValue)
        Calls find(targetValue, false).

      • set1Value

        public void set1Value​(int index,
                      float q0,
                      float q1,
                      float q2,
                      float q3)
        Sets the index 'th value to the given quaternion (x, y, z, w).

      • setValues

        public void setValues​(int start,
                      SbRotation[] newValues)
        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.

      • set1Value

        public void set1Value​(int index,
                      SbRotation newValue)
        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.

      • getValueAt

        public SbRotation getValueAt​(int i)

      • find

        public int find​(SbRotation targetValue,
                boolean addIfNotFound)
        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).

      • finishEditing

        public void finishEditing()
        Indicates that batch edits have finished. See startEditing().

      • startEditing

        public java.nio.FloatBuffer 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.

      • getValues

        public SbRotation[] getValues​(int start)
        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.

      • getDirectValues

        public java.nio.FloatBuffer getDirectValues​(int start)
        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.

      • setValue
