Detailed Description

Multiple-value field containing any number of RGB colors stored as three floats.

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 ]

represents the three colors red, green, and blue.

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 setValuesPointer() 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.

◆ setValuesPointer() [1/2]

void SoMFColor::setValuesPointer	(	int	num,
		const float *	userData
	)

Sets the field to contain the num values stored in userData array.

This array will not be copied into the field: it will be directly used by the field. If num and userData are not correctly specified, the results are undefined (and probably undesirable). param num is the number of values that userData contains and must be a positive integer. param userData is an array allocated by malloc or realloc and can be deallocated by free (no constructor or destructor is called). userData must not be NULL. Its size must be at least num*sizeof(valueType).

◆ startEditing()

SbColor * SoMFColor::startEditing ( )

inline

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.
