public class SoMFVec4f extends SoMField
Multiple-value field containing any number of four-dimensional vectors. A multiple-value field that contains any number of four-dimensional vectors.

SoMFVec4fs are written to file as one or more quadruples 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, 1.2 3.4 5.6 1, 98.6 -4e1 212 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.

  • Method Details

    • setValues

      @Deprecated(since="9.3.1") public void setValues(int start, int num, float[] xyzw)
      Deprecated.
      As of Open Inventor 9.3.1, use setValues(int, float[]) instead.
      Sets values from array of arrays of 4 floats.

    • setValues

      @Deprecated(since="9.3.1") public void setValues(int start, int num, SbVec4d[] vec4d)
      Deprecated.
      As of Open Inventor 9.3.1, use setValues(int, com.openinventor.inventor.SbVec4d[]) instead.
      Sets values from array of double precision vectors.

    • find

      public int find(SbVec4f targetValue)
      Calls find(targetValue, false).

    • getDirectValues

      public 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.

    • getValueAt

      public SbVec4f getValueAt(int i)

    • getValues

      public SbVec4f[] 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.

    • setValues

      public void setValues(int start, SbVec4f[] 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.

    • find

      public int find(SbVec4f 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).

    • setValue

      public void setValue(float x, float y, float z, float w)
      Sets to one value from 4 floats.

    • set1Value

      public void set1Value(int index, float[] xyzw)
      Sets one value from 4 floats in array.

    • finishEditing

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

    • startEditing

      public 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.

    • set1Value

      public void set1Value(int index, SbVec4f 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.

    • setValue

      public void setValue(SbVec4d vec4d)
      Sets to one value from double precision vector.

    • setValues

      public void setValues(int start, float[] xyzw)
      Sets values from the specified array of floats. The size of the array must be a multiple of 4.

    • setValuesBuffer

      public void setValuesBuffer(ByteBuffer userData)
      Sets the field to contain the values stored in userData. This data will not be copied into the field: it will be directly used by the field.

    • setValues

      public void setValues(int start, SbVec4d[] vec4d)
      Sets values from array of double precision vectors.

    • disableDeleteValues

      public void disableDeleteValues()
      Temporary disable value deleting.

    • setValue

      public void setValue(float[] xyzw)
      Sets to one value from 4 floats in array.

    • setValue

      public void setValue(SbVec4f newValue)
      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.

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class SoField

    • set1Value

      public void set1Value(int index, SbVec4d vec4d)
      Sets one value from double precision vector.

    • set1Value

      public void set1Value(int index, float x, float y, float z, float w)
      Sets one value from 4 floats.
