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.

Reimplemented from vtkProjectedAAHexahedraMapper.

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

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.

float* vtkOpenGLProjectedAAHexahedraMapper::ConvertScalars ( vtkDataArray inScalars)
protected

Convert the input scalar values to floats.

float* vtkOpenGLProjectedAAHexahedraMapper::ConvertPoints ( vtkPoints inPoints)
protected

Convert the input cell coordinates to floats.

virtual void vtkOpenGLProjectedAAHexahedraMapper::ProjectHexahedra ( vtkRenderer renderer,
vtkVolume volume 
)
protectedvirtual

Iterate over all the hexahedal input cells, sort and render them.

void vtkOpenGLProjectedAAHexahedraMapper::Initialize ( vtkRenderer renderer,
vtkVolume volume 
)
protected

Load the OpenGL extensions and allocate the vertex arrays.

void vtkOpenGLProjectedAAHexahedraMapper::UpdatePreintegrationTexture ( vtkVolume vome,
vtkDataArray scalars 
)
protected

Update the preintegration texture; this is needed whenever the mesh changes.

void vtkOpenGLProjectedAAHexahedraMapper::CreateProgram ( vtkRenderWindow w)
protected

Create the OpenGL geometry/vertex/fragment programs for hexahedral cell rendering.

void vtkOpenGLProjectedAAHexahedraMapper::SetState ( double *  observer)
protected

Set the OpenGL state for hexahedral cell rendering.

void vtkOpenGLProjectedAAHexahedraMapper::RenderHexahedron ( float  min[3],
float  max[3],
float  scalars[8] 
)
protected

Render a single axis-aligned hexahedal cell.

void vtkOpenGLProjectedAAHexahedraMapper::UnsetState ( )
protected

Restore the OpenGL state touched by SetState().
