virtual const char* vtkVolumeTextureMapper2D::GetClassName ( ) [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkVolumeTextureMapper.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

int vtkVolumeTextureMapper2D::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkVolumeTextureMapper.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

virtual int vtkVolumeTextureMapper2D::IsA ( const char * type ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkVolumeTextureMapper.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

vtkVolumeTextureMapper2D* vtkVolumeTextureMapper2D::SafeDownCast ( vtkObject * o ) [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkVolumeTextureMapper.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

void vtkVolumeTextureMapper2D::PrintSelf ( ostream & os,

vtkIndent index

) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkVolumeTextureMapper.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

vtkVolumeTextureMapper2D* vtkVolumeTextureMapper2D::New ( ) [static]

Instantiate object with no start, end, or progress methods.
Reimplemented from vtkProcessObject.
Reimplemented in vtkMesaVolumeTextureMapper2D, and vtkOpenGLVolumeTextureMapper2D.

virtual void vtkVolumeTextureMapper2D::SetTargetTextureSize ( int ,

int

) [virtual]

Target size in pixels of each size of the texture for downloading. Default is 512x512 - so a 512x512 texture will be tiled with as many slices of the volume as possible, then all the quads will be rendered. This can be set to optimize for a particular architecture. This must be set with numbers that are a power of two.

void vtkVolumeTextureMapper2D::SetTargetTextureSize ( int [2] )

Target size in pixels of each size of the texture for downloading. Default is 512x512 - so a 512x512 texture will be tiled with as many slices of the volume as possible, then all the quads will be rendered. This can be set to optimize for a particular architecture. This must be set with numbers that are a power of two.

virtual int* vtkVolumeTextureMapper2D::GetTargetTextureSize ( ) [virtual]

Target size in pixels of each size of the texture for downloading. Default is 512x512 - so a 512x512 texture will be tiled with as many slices of the volume as possible, then all the quads will be rendered. This can be set to optimize for a particular architecture. This must be set with numbers that are a power of two.

virtual void vtkVolumeTextureMapper2D::GetTargetTextureSize ( int & ,

int &

) [virtual]

Target size in pixels of each size of the texture for downloading. Default is 512x512 - so a 512x512 texture will be tiled with as many slices of the volume as possible, then all the quads will be rendered. This can be set to optimize for a particular architecture. This must be set with numbers that are a power of two.

virtual void vtkVolumeTextureMapper2D::GetTargetTextureSize ( int [2] ) [virtual]

Target size in pixels of each size of the texture for downloading. Default is 512x512 - so a 512x512 texture will be tiled with as many slices of the volume as possible, then all the quads will be rendered. This can be set to optimize for a particular architecture. This must be set with numbers that are a power of two.

virtual void vtkVolumeTextureMapper2D::SetMaximumNumberOfPlanes ( int ) [virtual]

This is the maximum number of planes that will be created for texture mapping the volume. If the volume has more voxels than this along the viewing direction, then planes of the volume will be skipped to ensure that this maximum is not violated. A skip factor is used, and is incremented until the maximum condition is satisfied.

virtual int vtkVolumeTextureMapper2D::GetMaximumNumberOfPlanes ( ) [virtual]

This is the maximum number of planes that will be created for texture mapping the volume. If the volume has more voxels than this along the viewing direction, then planes of the volume will be skipped to ensure that this maximum is not violated. A skip factor is used, and is incremented until the maximum condition is satisfied.

virtual void vtkVolumeTextureMapper2D::SetMaximumStorageSize ( int ) [virtual]

This is the maximum size of saved textures in bytes. If this size is large enough to hold the RGBA textures for all three directions (XxYxZx3x4 is the approximate value - it is actually a bit larger due to wasted space in the textures) then the textures will be saved.

This is the maximum size of saved textures in bytes. If this size is large enough to hold the RGBA textures for all three directions (XxYxZx3x4 is the approximate value - it is actually a bit larger due to wasted space in the textures) then the textures will be saved.
