Field containing a 2D array value.
This field contains a 2D array of values of a specified type. The setValue method allows you to specify the dimensions and type of data the array will contain. The CopyPolicy allows you to control whether Open Inventor will make a copy of the data and, if not, whether the application or Open Inventor is responsible for managing the memory.
In ASCII format, an SoSFArray2D is written to file in the following format:
The example below shows the definition of a 2x2 array of unsigned bytes with data values 0, 1, 2 and 3:
2 2 UBYTE 0 1 2 3
Below is a 2x3 array of floats:
2 3 FLOAT 0.5 1 .72 0.33 6.2e4 0.9

Reimplemented from SoSFArray.
Returns a read-only pointer to the 2D array's values and its dimensions and data type.
Returns a read-only pointer to the 2D array's values and its dimensions and data type.
const SoSFArray2D & SoSFArray2D::operator= | ( | const SoSFArray2D & | f | ) |
Copy from another field of same type.
void SoSFArray2D::setValue | ( | const SbVec2i32 & | size, |
DataType | dataType, | ||
const void * | data, | ||
CopyPolicy | copy = COPY |
||

Fill the 2D array with data of the specified dimensions and type using the specified copy policy.
void SoSFArray2D::setValue | ( | const SbVec2s & | size, |
DataType | dataType, | ||
const void * | data, | ||
CopyPolicy | copy = COPY |
||
) |
Fill the 2D array with data of the specified dimensions and type using the specified copy policy.
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. setValue(), etc.). Fields, engines or sensors connected to this field are not triggered 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.
