Detailed Description

Compute 2D texture image extent to transfer any data array as 2D image chunks to GPU memory. It is also used to transfer back 2D texture chunk as part of a data array.

See also:: Used by the vtkKWEGPUArrayCalculator.

		vtkObject
	)

void vtkKWEDataArrayStreamer::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Reimplemented from vtkObject.

virtual void vtkKWEDataArrayStreamer::SetNumberOfTuples ( vtkIdType ) [virtual]

Data array to split. Initial value is 0.

virtual vtkIdType vtkKWEDataArrayStreamer::GetNumberOfTuples ( ) [virtual]

Data array to split. Initial value is 0.

virtual void vtkKWEDataArrayStreamer::SetMax3DTextureSize ( int ) [virtual]

Maximum size of any dimension of a 3D texture. Initial value is 16, the minimal value of the OpenGL specifications.

virtual int vtkKWEDataArrayStreamer::GetMax3DTextureSize ( ) [virtual]

Maximum size of any dimension of a 3D texture. Initial value is 16, the minimal value of the OpenGL specifications.

virtual void vtkKWEDataArrayStreamer::SetMaxTextureSize ( int ) [virtual]

Maximum size of any dimension of a 1D or 2D texture. Initial value is 64, the minimal value of the OpenGL specifications.

virtual int vtkKWEDataArrayStreamer::GetMaxTextureSize ( ) [virtual]

Maximum size of any dimension of a 1D or 2D texture. Initial value is 64, the minimal value of the OpenGL specifications.

virtual void vtkKWEDataArrayStreamer::SetMaxTextureMemorySizeInBytes ( vtkIdType ) [virtual]

User-defined maximum size in bytes of a texture in GPU memory. Initial value is 134217728 bytes (128*2^20=128Mb). In a 32-bit build, this ivar can encode up to 4GB. A null value means no limit.

virtual vtkIdType vtkKWEDataArrayStreamer::GetMaxTextureMemorySizeInBytes ( ) [virtual]

User-defined maximum size in bytes of a texture in GPU memory. Initial value is 134217728 bytes (128*2^20=128Mb). In a 32-bit build, this ivar can encode up to 4GB. A null value means no limit.

virtual void vtkKWEDataArrayStreamer::SetTupleSize ( int ) [virtual]

Size of a tuple in bytes (number of components*size of type). If the streamer is used by several dataarray at the same time, the user should set its value to the maximum tuple size. Initial value is 1.

virtual int vtkKWEDataArrayStreamer::GetTupleSize ( ) [virtual]

Size of a tuple in bytes (number of components*size of type). If the streamer is used by several dataarray at the same time, the user should set its value to the maximum tuple size. Initial value is 1.

virtual void vtkKWEDataArrayStreamer::SetMaxNumberOfTuplesPerBlock ( vtkIdType ) [virtual]

User-defined maximum number of tuples per block. If 0, this value is ignored. Initial value is 0.

virtual vtkIdType vtkKWEDataArrayStreamer::GetMaxNumberOfTuplesPerBlock ( ) [virtual]

User-defined maximum number of tuples per block. If 0, this value is ignored. Initial value is 0.

void vtkKWEDataArrayStreamer::Begin ( )

Place the cursor on the first chunk, if any.

bool vtkKWEDataArrayStreamer::IsDone ( )

Is the iteration over?

void vtkKWEDataArrayStreamer::Next ( )

Go the next chunk, if any.
