Detailed Description

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

Constructor & Destructor Documentation

virtual makVrv::DtOsgShaderManager::~DtOsgShaderManager ( )

virtual

DTOR.

Member Function Documentation

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

static

Get/create instance of sky object manager.

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

static

Get the name this class is registered by.

void makVrv::DtOsgShaderManager::setPerPixelLightingEnabled

(

bool

enabled

)

Toggles global use of shader-based lighting effects.

bool makVrv::DtOsgShaderManager::getPerPixelLightingEnabled

(

)

const

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

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

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)

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

threadsafe implementation of generateShaders

void makVrv::DtOsgShaderManager::removeShaders

(

osg::Node *

node

)

Remove virtual shader programs for a graph.

node: Graph for which to remove shader components

void makVrv::DtOsgShaderManager::ts_removeShaders

(

osg::Node *

node

)

threadsafe implementation of removeShaders

void makVrv::DtOsgShaderManager::optimizeStateSharing

(

osg::Node *

node

)

Runs a pass over the provided graph and consolidates equivalent state attributes.

This can result in better draw performance by reducing OpenGL state changes

const std::string& makVrv::DtOsgShaderManager::getShaderFolderPath

(

)

const

Gets the location of the shader sources.

void makVrv::DtOsgShaderManager::cullReset

(

)

Clear the internal list of light sources and implement state changes when the cull visitor is reset each frame.

void makVrv::DtOsgShaderManager::disableShaders

(

osg::StateSet *

stateSet

)

Disable per-pixel lighting on this state set.

void makVrv::DtOsgShaderManager::installEnvironmentMap

(

osg::Camera *

camera

)

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.
