Detailed Description

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:

Two numbers define the dimensions of the array
One string defines the type of the data:
- BYTE for signed bytes
- UBYTE for unsigned bytes
- SHORT for signed shorts
- USHORT for unsigned shorts
- INT32 for signed 32 bits ints
- UINT32 for unsigned 32 bits ints
- FLOAT for floating point values
A list of values in decimal, hexadecimal, or octal format for integers or in standard scientific notation for float. Numbers are separated by a blank (space, tab, return...).

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

EXAMPLE

SbVec2i32 size(2,2);
unsigned char* data = new unsigned char[4]; 
. . .
SoIndexedTexture2* indexedTexture = new SoIndexedTexture2();
indexedTexture->imageIndex.setValue(size, SoSFArray::UNSIGNED_BYTE, data); 

Constructor & Destructor Documentation

◆ SoSFArray2D()

Destructor.

Member Function Documentation

◆ getClassTypeId()

static SoType SoSFArray2D::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getSize()

SbVec2i32 SoSFArray2D::getSize ( ) const

inline

Returns the dimensions of the array.

Definition at line 192 of file SoSFArray2D.h.

◆ getTypeId()

virtual SoType SoSFArray2D::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Reimplemented from SoSFArray.

◆ getValue() [1/2]

const void * SoSFArray2D::getValue	(	SbVec2i32 &	size,
		DataType &	dataType
	)		const

Returns a read-only pointer to the 2D array's values and its dimensions and data type.

◆ getValue() [2/2]

const void * SoSFArray2D::getValue	(	SbVec2s &	size,
		DataType &	dataType
	)		const

Returns a read-only pointer to the 2D array's values and its dimensions and data type.

◆ operator=()

const SoSFArray2D & SoSFArray2D::operator= ( const SoSFArray2D & f )

Copy from another field of same type.

◆ setValue() [1/2]

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.

◆ setValue() [2/2]

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.

◆ startEditing() [1/2]

void * SoSFArray2D::startEditing	(	SbVec2i32 &	size,
		DataType &	dataType
	)

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.

◆ startEditing() [2/2]

void * SoSFArray2D::startEditing	(	SbVec2s &	size,
		DataType &	dataType
	)
