Detailed Description

Field containing a 3D array value.

This field contains a 3D array of values of a specified type. The setValue method allows you to specify the dimensions and type of data the array will contain, as well as the number of significant bits. 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 SoSFArray3D is written to file in the following format:

Three 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...).
One number defines the number of significant bits

The example below shows the definition of a 2x2x2 array of unsigned bytes with data values 0, 1, 2, 3, 4, 5, 6, 7 and a number of significant bits of 8:

  2 2 2 UBYTE
  0 1
  2 3
  4 5
  6 7
  8
* \verbatim
*
* An SoSFArray3D may be empty or contain only dimension and type information,
* but no data values.  With no data values the previous example would be
* written with the prefix "NODATA" like this:
* \verbatim
  NODATA 2 2 2 UBYTE
  8

Member Function Documentation

◆ getClassTypeId()

static SoType SoSFArray3D::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getNumSigBits()

unsigned int SoSFArray3D::getNumSigBits ( ) const

inline

Returns the number of significant bits.

Definition at line 161 of file SoSFArray3D.h.

◆ getSize()

const SbVec3i32 & SoSFArray::getSize ( ) const

inline

Returns the dimensions of the array.

Definition at line 151 of file SoSFArray.h.

◆ getTypeId()

virtual SoType SoSFArray3D::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Reimplemented from SoSFArray.

◆ getValue() [1/2]

void * SoSFArray::getValue ( ) const

inline

Returns a read-only pointer to the array's values.

Definition at line 108 of file SoSFArray.h.

◆ getValue() [2/2]

const void * SoSFArray::getValue	(	SbVec3i32 &	size,
		SbDataType &	dataType
	)		const

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

◆ operator=()

const SoSFArray3D & SoSFArray3D::operator= ( const SoSFArray3D & f )

Copy from another field of same type.

◆ operator==()

virtual int SoSFArray3D::operator== ( const SoSFArray3D & f ) const

virtual

Returns TRUE if all of the values of this field equal those of the given field f.

If the fields are different types FALSE will always be returned.

◆ setValue() [1/2]

void SoSFArray3D::setValue	(	const SbVec3i32 &	size,
		const SbDataType &	dataType,
		unsigned int	numSigBits,
		const void *	data,
		CopyPolicy	copy
	)

Fill the array with data of the specified dimensions and type using the specified copy policy.

◆ setValue() [2/2]

void SoSFArray3D::setValue	(	const SbVec3i32 &	size,
		unsigned int	numSigBits,
		SoMemoryObject *	memObj,
		CopyPolicy	copy
	)

Fill the array with data of the specified dimensions and type using the specified copy policy.

◆ startEditing()

void * SoSFArray::startEditing	(	SbVec3i32 &	size,
		SbDataType &	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.
