Detailed Description

OpenGL implementation of a volume mapper for axis-aligned hexahedra.

High quality volume renderer for axis-aligned hexahedra

Implementation:: Implementation by Stephane Marchesin (steph.nosp@m.ane..nosp@m.march.nosp@m.esin.nosp@m.@gmai.nosp@m.l.co.nosp@m.m) CEA/DIF - Commissariat a l'Energie Atomique, Centre DAM Ile-De-France BP12, F-91297 Arpajon, France.

Implementation:: This mapper implements the paper "High-Quality, Semi-Analytical Volume Rendering for AMR Data", Stephane Marchesin and Guillaume Colin de Verdiere, IEEE Vis 2009.

Member Function Documentation

static int vtkOpenGLProjectedAAHexahedraMapper::IsTypeOf ( const char * name ) [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 vtkProjectedAAHexahedraMapper.

virtual int vtkOpenGLProjectedAAHexahedraMapper::IsA ( const char * name ) [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 vtkProjectedAAHexahedraMapper.

static vtkOpenGLProjectedAAHexahedraMapper* vtkOpenGLProjectedAAHexahedraMapper::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkProjectedAAHexahedraMapper.

virtual vtkObjectBase* vtkOpenGLProjectedAAHexahedraMapper::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkProjectedAAHexahedraMapper.

vtkOpenGLProjectedAAHexahedraMapper* vtkOpenGLProjectedAAHexahedraMapper::NewInstance ( ) const

Reimplemented from vtkProjectedAAHexahedraMapper.

static vtkOpenGLProjectedAAHexahedraMapper* vtkOpenGLProjectedAAHexahedraMapper::New ( ) [static]

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

Reimplemented from vtkProjectedAAHexahedraMapper.

virtual void vtkOpenGLProjectedAAHexahedraMapper::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 vtkProjectedAAHexahedraMapper.

bool vtkOpenGLProjectedAAHexahedraMapper::IsRenderSupported ( vtkRenderWindow * w ) [virtual]

Check if the required OpenGL extensions are supported by the OpenGL context attached to the render window `w'.

Implements vtkProjectedAAHexahedraMapper.

void vtkOpenGLProjectedAAHexahedraMapper::Render	(	vtkRenderer *	ren,
		vtkVolume *	vol
	)		`[virtual]`

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS Render the volume

Implements vtkUnstructuredGridVolumeMapper.

void vtkOpenGLProjectedAAHexahedraMapper::ReleaseGraphicsResources ( vtkWindow * ) [virtual]

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE Release any graphics resources that are being consumed by this mapper. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkUnstructuredGridVolumeMapper.
