Member Function Documentation

virtual int VAPoR::IsolineRenderer::_initializeGL ( )

Required virtual method performs any needed OpenGL initialization.

Implements VAPoR::RendererBase.

virtual int VAPoR::IsolineRenderer::_paintGL ( DataMgrV3_0 dmgr)

Required virtual method, renders the isolines.

[in]dmgris the DataMgrV3_0 that supplies the data

Implements VAPoR::Renderer.

int VAPoR::IsolineRenderer::buildLineCache ( DataMgrV3_0 dmgr)

Rebuild the entire line cache at the current time step

[in]dmgrCurrent DataMgr
bool VAPoR::IsolineRenderer::cacheIsValid ( int  timestep)

Check if the current cache is valid

[in]timesteptime step to be checked.
true if cache is valid

Definition at line 73 of file isolinerenderer.h.

static Renderer* VAPoR::IsolineRenderer::CreateInstance ( Visualizer v,
RenderParams rp 

Static method to create a renderer given the associated Params instance and visualizer

[in]Visualizer*pointer to the visualizer where this will draw
[in]RenderParams*pointer to the IsolineParams associated with this renderer
IsolineRenderer* new IsolineRenderer instance.

Definition at line 54 of file isolinerenderer.h.

const std::map<pair<int,int>,vector<float*> >& VAPoR::IsolineRenderer::GetLineCache ( )

Obtain the current line cache. Each timestep and isovalue is associated with a vector of triples of floats.

current lineCache

Definition at line 81 of file isolinerenderer.h.

virtual void VAPoR::IsolineRenderer::invalidateCache ( )

Virtual method results in entire cache being invalidated.

Reimplemented from VAPoR::Renderer.

void VAPoR::IsolineRenderer::invalidateLineCache ( int  timestep)

Invalidate the cache of isolines at a single time step

[in]timestepis the Time Step to be invalidated.
virtual void VAPoR::IsolineRenderer::setAllDataDirty ( )

Invalidate cache when necessary to re-obtain data Must be called whenever parameters are changed so as to require a new generation of isolines

Reimplemented from VAPoR::Renderer.
