DESCRIPTION¶

A multiple-value field that contains any number of RGB colors, stored as instances of SbColor. Values may be set in either RGB (red, green, blue) or HSV (hue, saturation, value) color spaces.

SoMFColors are written to file as one or more RGB triples of floating point numbers in standard scientific notation. 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 0.0, 0 1 0, 0 0 1 ]

METHODS¶

void setValues(int start, int num, const float rgb[][3])

void setHSVValues(int start, int num, const float hsv[][3])

Sets num values starting at index start to the RGB (or HSV) values specified by the given array of floats. Each float should be in the range 0.0 to 1.0, and there must be 3*num floats in the array.

void setValue(const SbVec3f &vec)

void setValue(float red, float green, float blue)

void setHSVValue(float hue, float saturation, float value)

void setValue(const float rgb[3])

void setHSVValue(const float hsv[3])

Sets the field to contain one and only one value, the given color (expressed as either RGB or HSV floating point values in the range 0.0 to 1.0), and deletes the second and subsequent values.

void set1Value(index, const SbVec3f &vec)

void set1Value(index, float r, float g, float b)

void set1HSVValue(index, float h, float s, float v)

void set1Value(index, const float rgb[3])

void set1HSVValue(index, const float hsv[3])

Sets one value in the array to the given color. The array will be expanded and filled with zeroes as necessary.

static SoType getClassTypeId()

virtual void getTypeId() const

Returns the type for this class or a particular object of this class.

const SbColor & 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 SbColor * 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 SbColor & 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 SbColor *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 SbColor & newValue)

Sets the index'th value in the array to newValue. The array will be automatically expanded, if necessary.

const SbColor & operator =(const SbColor & newValue)

void setValue(const SbColor & newValue)

Sets the first value in the array to newValue, and deletes the second and subsequent values.

int operator ==(const SoMFColor &f) const

int operator !=(const SoMFColor &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).

SbColor * 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.
