Member Enumeration Documentation

Layer organization.

Enumerator:
CONTIGUOUS_PER_PIXEL 

values of each layer are grouped by pixel (e.g.

: RGBA RGBA ... )

CONTIGUOUS_PER_LAYER 

values of each layer are separated (e.g.

: RRRR... GGGG... BBBB... AAAA... )

CONTIGUOUS_PER_PLANE 

values of each layer are separated by 2d simple plane (e.g.

: RR... GG... BB... RR... GG... BB...)

CONTIGUOUS_PER_VOLUME 

values of each layer are separated by 3d simple volume


Constructor & Destructor Documentation

SoMemoryDataAdapter::SoMemoryDataAdapter (  ) 

Default constructor.

Init an image with one voxel unit of one component of type UNSIGNED_BYTE.

Please use createMemoryDataAdapter() to create a Memory adapter from existing block of memory.


Member Function Documentation

static SoMemoryDataAdapter* SoMemoryDataAdapter::createMemoryDataAdapter ( const SbVec4i32 dimension,
SbImageDataType  imageInfos,
LayerOrganization  organization,
SoBufferObject data 
) [static]

Factory method that creates an adapter from an existing block of memory.

Note: An SoMemoryDataAdapter stores its data in CONTIGUOUS_PER_PIXEL. Data may be copied and reorganized if LayerOrganization is not CONTIGUOUS_PER_PIXEL.

Parameters:
dimension Dimension of the buffer (width, height, depth, timestep).
imageInfos Define the format type of data.
organization Define the organization of layers.
data Buffer object to map. If NULL a buffer is automatically allocated and its values are initialized to 0.
SoBufferObject* SoMemoryDataAdapter::getBufferObject (  ) 

Returns the buffer object containing the image data.

Data are stored line by line, slice by slice, channels in CONTIGUOUS_PER_PIXEL.

static SoType SoMemoryDataAdapter::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoImageDataAdapter.

virtual SoType SoMemoryDataAdapter::getTypeId (  )  const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from SoImageDataAdapter.
