Public Attributes
int8_t	match_flags = 0
	Do not update lighting unless flags is same as this value.

bool	is_active = true
	Toggle to check if the Component is active, actual meaning heavily depends of the component type.

Detailed Description

Lighting component.

Handles lighting + reflections of the scene

Constructor & Destructor Documentation

Lighting()

oe::component::Lighting::Lighting	(	oe::scene::Manager &	,
		oe::render::TextureManager &	texture_manager
	)

Create the component.

Todo:

texture_manager needed ?

Member Function Documentation

fillReflectionsShader()

void oe::component::Lighting::fillReflectionsShader ( oe::render::ShaderBase &  shader ) const

noexcept

Send Reflection probes data to the shader.

Parameters

shader

fillShader()

void oe::component::Lighting::fillShader ( oe::render::ShaderBase &  shader ) const

noexcept

Send All lights data to the shader.

Parameters

shader

fillTransparencyShader()

void oe::component::Lighting::fillTransparencyShader ( oe::render::ShaderBase &  shader ) const

noexcept

Send Transparency data (ie refractive buffer) to the shader.

Parameters

shader

onUpdate()

virtual void oe::component::Lighting::onUpdate ( const std::chrono::nanoseconds  , const int8_t    )

overridevirtual

Update lighting.

Parameters

delta	seconds since last call of update
flags	custom flags

Reimplemented from oe::component::Component.

setRefractionTexture()

void oe::component::Lighting::setRefractionTexture ( const std::shared_ptr< oe::render::Texture > &  refraction_texture )

inline

Set texture that will be used as source for refractive surfaces.

Note

If you use the pipeline, this texture is already set to use the output from lighting pass

Parameters

shader
