RendererBase is a base class of Renderer, for special rendering tasks that are not associated with RenderParams instances. For example the VizFeatureRenderer has a special role during Visualizer OpenGL rendering. RendererBase instances perform rendering in a VAPOR Visualizer but are not associated with RenderParams instances.

Member Function Documentation

virtual int VAPoR::RendererBase::_initializeGL ( )

protectedpure virtual

Pure virtual method Any OpenGL initialization is performed in initializeGL It will be called from an OpenGL rendering context.

Implemented in VAPoR::IsolineRenderer, and VAPoR::HelloRenderer.

const string VAPoR::RendererBase::getMyName ( ) const

inline

Identify the name of the current renderer (for error messages)

Returns

name (i.e. tag) of renderer

Definition at line 67 of file renderer.h.

Visualizer* VAPoR::RendererBase::GetVisualizer ( )

inline

Obtain the Visualizer associated with this Renderer.

Definition at line 59 of file renderer.h.

virtual int VAPoR::RendererBase::initializeGL ( )

virtual

Pure virtual method Any OpenGL initialization is performed in initializeGL It will be called from an OpenGL rendering context. Sets _initialized to true if successful.

virtual void VAPoR::RendererBase::invalidateCache ( )

inlinevirtual

Invalidate all caches associated with a Renderer instance Default does nothing

Reimplemented in VAPoR::Renderer, and VAPoR::IsolineRenderer.

Definition at line 71 of file renderer.h.

bool VAPoR::RendererBase::isInitialized ( )

inline

Identify whether the renderer has been initialized

Return values

bool	_initialized

Definition at line 63 of file renderer.h.
