Multiple-value field containing any number of RGBA colors stored as four floats.
A multiple-value field that contains any number of RGBA colors, stored as instances of SbColorRGBA. RGBA stands for red, green, blue and alpha. Values should be in the range 0 to 1. Alpha is the inverse of "transparency", in other words 0 is fully transparent and 1 is fully opaque.
Values can also be specified or queried in the HSV (hue, saturation and value) color space, but values are stored internally as RGBA values.
SoMFColorRGBAs are written to file as one or more RGBA quadruples 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 0.5, 0 1 0 1, 0 0 1 .25 ]
represents the three colors half transparent red, fully opeque green, and one quarter transparent blue.

int | num, | ||
const float | hsva[][4] | ||
) |
Sets num HSV (hue, saturation and value) plus Alphe color values from an array of arrays of 4 floats.

void SoMFColorRGBA::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).
void SoMFColorRGBA::setValuesPointer | ( | int | num, |
float * | userData | ||
) |
|
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.
