makVrv::DtOsgShaderManager Class Reference

DtOsgShaderManager injects custom shaders into the scenes, and keeps their uniform parameters set to match fixed function pipeline capabilities as much as possible.

Member Function Documentation

static DtOsgShaderManager& makVrv::DtOsgShaderManager::instance ( DtDe &  de )

static

Get/create instance of shader manager.

static std::string makVrv::DtOsgShaderManager::theClassName ( )

static

Get the name this class is registered by.

virtual void makVrv::DtOsgShaderManager::setPerPixelLightingEnabled ( bool  enabled )

virtual

Toggles global use of shader-based lighting effects.

virtual bool makVrv::DtOsgShaderManager::getPerPixelLightingEnabled ( ) const

virtual

Retrieves whether per-pixel shader-based lighting is active.

virtual void makVrv::DtOsgShaderManager::generateShaders ( osg::Node *  node, const std::string &  name = "", bool  shareState = true, bool  force = false  )

virtual

Generates virtual shader programs for a graph. node: Graph for which to generate shader components name: Optional name to give to virtual programs (useful for debugging) shareState: Run a pass on the node to share equivalent state attributes. This is equivalent to calling optimizeStateSharing(node) after calling this. force: Force shader generation on the node graph, disregarding the ignore userdata flag (see osgEarth::ShaderGenerator::setIgnoreHint)

virtual void makVrv::DtOsgShaderManager::ts_generateShaders ( osg::Node *  node, DtOsgFileCache &  fileCache, const std::string &  name = "", bool  shareState = true, bool  force = false  )

virtual

threadsafe implementation of generateShaders

virtual void makVrv::DtOsgShaderManager::removeShaders ( osg::Node *  node )

virtual

Remove virtual shader programs for a graph. node: Graph for which to remove shader components.

virtual void makVrv::DtOsgShaderManager::ts_removeShaders ( osg::Node *  node )

virtual

threadsafe implementation of removeShaders

virtual void makVrv::DtOsgShaderManager::optimizeStateSharing ( osg::Node *  node )

virtual

Runs a pass over the provided graph and consolidates equivalent state attributes. This can result in better draw performance by reducing OpenGL state changes.

virtual const std::string& makVrv::DtOsgShaderManager::shaderFolderPath ( ) const

virtual

Gets the location of the shader sources.

virtual void makVrv::DtOsgShaderManager::disableShaders ( osg::StateSet *  stateSet )

virtual

Disable per-pixel lighting on this state set.

virtual void makVrv::DtOsgShaderManager::installEnvironmentMap ( osg::Camera *  camera )

virtual

Installs an environment map texture/uniform on the specified camera. This needs to be per camera so that the correct environment map is used based on the camera.

boost::shared_mutex& makVrv::DtOsgShaderManager::optimizeStateSetMutex

(

)

get the optimize stateset mutex, used by DtOsgEarthFeatureDataBroker and DtIndirectGeometryRegistry to avoid both running their visitors at the same time this should go away once we refactor the DtIndirectRegistry stuff enough to fix this problem.
