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 vtkTypeRevisionMacro found in vtkSetGet.h.

void vtkVolumeTextureMapper2D::PrintSelf ( ostream & os,

vtkIndent indent

) [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]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject.

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 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.
