	)

virtual

Implement base class method. Perform the render.

Reimplemented from vtkImageSliceMapper.

void vtkOpenGLImageSliceMapper::ReleaseGraphicsResources ( vtkWindow * )

virtual

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.

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,

protected

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

void vtkOpenGLImageSliceMapper::RenderPolygon	(	vtkPoints *	points,
		const int	extent[6],
		bool	textured
	)

protected

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

void vtkOpenGLImageSliceMapper::RenderBackground	(	vtkPoints *	points,
		const int	extent[6],
		bool	textured
	)

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.

		int &	ydim,
		int	imageSize[2],
		int	textureSize[2]
	)

protectedvirtual

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).

Reimplemented from vtkImageMapper3D.

bool vtkOpenGLImageSliceMapper::TextureSizeOK ( const int size[2] )

protected

Test whether a given texture size is supported. This includes a check of whether the texture will fit into texture memory.

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]
	)

protectedvirtual

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).

Reimplemented from vtkImageMapper3D.

bool vtkOpenGLImageSliceMapper::TextureSizeOK ( const int size[2] )

protected

Test whether a given texture size is supported. This includes a check of whether the texture will fit into texture memory.

void vtkOpenGLImageSliceMapper::CheckOpenGLCapabilities ( vtkOpenGLRenderWindow * renWin )

protected

Check various OpenGL capabilities
