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 data is NULL, a buffer is provided to simulated a blank image.
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.
