Detailed Description

shader module.

Function Documentation

void shader::DisableShader

(

osg::StateSet &

stateSet

)

Disable shader on a node.

INLINE Conf& shader::GetConf

(

void

)

void shader::Init

(

const base::InitArgs &

initArgs

)

Initialize module.

ostream & shader::operator<<	(	ostream &	strm,
		const Conf &	conf
	)

Print Conf configuration.

void shader::ResetShaderUniformsForModel

(

Node &

node

)

Reset MOST (not all) shader uniforms.

void shader::ResetShaderUniformsForRootNode

(

Node &

node

)

Reset ALL shader uniforms. Some uniforms are attached only to the root node.

void shader::SetShaderFog	(	Node &	node,
		const fp	fogDensity,
		const RGBA	fogColor
	)

Set fog parameters.

template<typename T>

CLASS_METHOD void shader::SetShaderUniform	(	const string &	uniformName,
		const T &	val,
		Node &	node
	)			[inline]

Convenience function to assign a uniform to a node. This is slow -- it's only meant for one-time assignment of a uniform. If a uniform will be changed frequently, instead use "new Uniform".

template<typename T>

CLASS_METHOD void shader::SetShaderUniform	(	const string &	uniformName,
		const T &	val,
		RefPtr< osg::StateSet >	stateset
	)			[inline]

Convenience function to assign a uniform to a node. This is slow -- it's only meant for one-time assignment of a uniform. If a uniform will be changed frequently, instead use "new Uniform".

void shader::Start

(

void

)

Start module.
