Detailed Description

OpenGL mapper for image slice display.

vtkOpenGLImageSliceMapper is a concrete implementation of the abstract class vtkImageSliceMapper that interfaces to the OpenGL library.

Thanks:: Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.

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 vtkImageSliceMapper.

void vtkOpenGLImageSliceMapper::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkImageSliceMapper.

void vtkOpenGLImageSliceMapper::Render	(	vtkRenderer *	ren,
		vtkImageSlice *	prop
	)

overridevirtual

Implement base class method.

Perform the render.

Reimplemented from vtkImageSliceMapper.

void vtkOpenGLImageSliceMapper::ReleaseGraphicsResources ( vtkWindow * )

overridevirtual

Release any graphics resources that are being consumed by this mapper, the image texture in particular.

Using the same texture in multiple render windows is NOT currently supported.

Reimplemented from vtkImageSliceMapper.

void vtkOpenGLImageSliceMapper::RecursiveRenderTexturedPolygon	(	vtkRenderer *	ren,
		vtkImageProperty *	property,
		vtkImageData *	image,
		int	extent[6],
		bool	recursive
	)

protected

Recursive internal method, will call the non-recursive method as many times as necessary if the texture must be broken up into pieces that are small enough for the GPU to render.

void vtkOpenGLImageSliceMapper::RenderTexturedPolygon	(	vtkRenderer *	ren,
		vtkImageProperty *	property,
		vtkImageData *	image,
		int	extent[6],
		bool	recursive
	)

protected

Non-recursive internal method, generate a single texture and its corresponding geometry.

void vtkOpenGLImageSliceMapper::RenderPolygon	(	vtkActor *	actor,
		vtkPoints *	points,
		const int	extent[6],
		vtkRenderer *	ren
	)

protected

Basic polygon rendering, if the textured parameter is set the tcoords are included, otherwise they aren't.

void vtkOpenGLImageSliceMapper::RenderBackground	(	vtkActor *	actor,
		vtkPoints *	points,
		const int	extent[6],
		vtkRenderer *	ren
	)

protected

Render the background, which means rendering everything within the plane of the image except for the polygon that displays the image data.

void vtkOpenGLImageSliceMapper::BindFragmentProgram	(	vtkRenderer *	ren,
		vtkImageProperty *	property
	)

protected

Bind the fragment program, and generate it first if necessary.

vtkStdString vtkOpenGLImageSliceMapper::BuildFragmentProgram ( vtkImageProperty * property )

protected

Build the fragment program to use with the texture.

void vtkOpenGLImageSliceMapper::ComputeTextureSize	(	const int	extent[6],
		int &	xdim,
		int &	ydim,
		int	imageSize[2],
		int	textureSize[2]
	)

overrideprotectedvirtual

Given an extent that describes a slice (it must have unit thickness in one of the three directions), return the dimension indices that correspond to the texture "x" and "y", provide the x, y image size, and provide the texture size (padded to a power of two if the hardware requires).
