Class SoMFPlane

  • public class SoMFPlane
extends SoMField
    Field containing several plane equations. A field containing one or more plane equations.

    SoMFPlanes are written to file as groups of four floating point values separated by whitespace. In each set of four values, the first three are the normal direction of the plane, the fourth is the distance of the plane from the origin (in the direction of the normal).

    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 0 100, ]

    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 Detail

      • find

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

      • getValueAt

        public SbPlane getValueAt​(int i)

      • 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.

      • equals

        public boolean equals​(java.lang.Object obj)
        Overrides:
        equals in class SoField

      • setValue

        public void setValue​(SbPlane 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.

      • set1Value

        public void set1Value​(int index,
                      SbPlane 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.

      • disableDeleteValues

        public void disableDeleteValues()
        Temporary disable value deleting.

      • getValues

        public SbPlane[] 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.

      • setValues

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