Detailed Description

Sliceable objects can draw themselves in a 2D texture.

The slice information is provided on demand as a ViewState information.

Member Function Documentation

◆ getReferential()

virtual const Referential* anatomist::Sliceable::getReferential ( ) const

pure virtual

Implemented in anatomist::SliceableObject, anatomist::Fusion2D, anatomist::Fusion2DMesh, and anatomist::VectorField.

◆ glAllowedTexRGBInterpolation()

virtual bool anatomist::Sliceable::glAllowedTexRGBInterpolation ( unsigned tex = 0 ) const

virtual

Reimplemented from anatomist::GLComponent.

◆ glBuildTexImage()

virtual carto::VolumeRef<AimsRGBA> anatomist::Sliceable::glBuildTexImage	(	const ViewState &	state,
		unsigned	tex,
		int	dimx = `-1`,
		int	dimy = `-1`,
		bool	useTexScale = `true`
	)		const

virtual

If you make non-standard textures (ie not from a palette), overload this function.

New in Anatomist 4.5, it is used by glMakeTexImage, and may also be used to save the texture data of an arbitrary object.

Parameters

dimx	and dimy are target texture sizes. If left to -1 (default), the size is calculated internally.
useTexScale	if true (default), allow using OpenGL scaling in texture space. Otherwise the palette image will be adapted to fit the scale.

Reimplemented from anatomist::GLComponent.

◆ glDimTex()

virtual unsigned anatomist::Sliceable::glDimTex	(	const ViewState &	,
		unsigned	tex = `0`
	)		const

virtual

texture dimension (1, 2 [or 3])

◆ glMakeTexImage()

virtual bool anatomist::Sliceable::glMakeTexImage	(	const ViewState &	state,
		const GLTexture &	gltex,
		unsigned	tex
	)		const

virtual

If you make non-standard textures (ie not from a palette), overload this function to fill gltex.

Since Anatomist 4.5, glMakeTexImage calls glBuildTexImage, which is actually the method to be overloaded by subclasses.

Returns: true on success, false if a texture could not be created

Reimplemented from anatomist::GLComponent.

virtual const Sliceable* anatomist::Sliceable::sliceableAPI ( ) const

inlinevirtual

virtual bool anatomist::Sliceable::update2DTexture	(	AImage &	,

virtual

this function must be overloaded to actually fill the slice image

Reimplemented in anatomist::AVolume< T >, anatomist::AVolume< float >, and anatomist::Fusion2D.

Referenced by anatomist::AVolume< float >::operator()().

◆ viewStateID()

virtual std::string anatomist::Sliceable::viewStateID	(	glPart	part,
		const ViewState &
	)		const

virtual

Makes a unique ID from a viewstate.

The ID must be unique within the GLComponent instance and for the part part. Depending on the aspects of the viewstate to take into account, subclasses may have to overload it.

For instance, a mesh may build an ID only taking time into account, whereas a volume slice must also code the slice position and orientation into the ID.
