Inheritance diagram for Wizt::RenderNamespace::Lighting:

Public Member Functions
unsigned	defineLightFunctions (glsl &lightshader) const
	Defines all the light functions as provided by the LightSource shaders managed here, with increasing light source function name.
bool	isYoungerThan (const MemCore::Ageable &) const

constexpr	Ageable (const Ageable &A) noexcept
	Copy constructor.
	Ageable (const volatile Ageable &A) noexcept

	Comparison operator.
bool	isOlderThan (const Ageable &a) const noexcept
	Comparison operator.
bool	isYoungerThan (const Ageable &a) const noexcept

	Comparision operator.
bool	operator>= (const Ageable &a) const noexcept
	Comparision operator.
bool	operator>= (const volatile Ageable &a) const volatile noexcept
	Comparison operator.
constexpr void	resetAge () noexcept
	Set time value to InfinitelyOld().
void	setInfinitelyNew () noexcept
	Set time value to InfinitelyOld().
age_t	time_value () const noexcept
	Return an object's current age.
age_t	time_value () const volatile noexcept
	Return an object's current age.
Ageable &	touch () noexcept
	Mark the current object as being modified "now".
age_t	update (age_t age) noexcept
	Set the age of the current object to a specific age if that is newer than the current one.
age_t	update (const Ageable &Other) noexcept
	Set the age of the current object to the age of another object if that other one is newer than the current one.
age_t	update (const volatile Ageable &Other) volatile noexcept
	Set the age of the current object to the age of another object if that other one is newer than the current one.
	~Ageable () noexcept
	Destructor.

Static Public Member Functions
static glsl	getEffectiveLightName (glsl &lightshader, unsigned LightNr)

static age_t	now () noexcept
	Return the current global time.

Static Public Attributes

getEffectiveLightName()

RenderNamespace::glsl Wizt::RenderNamespace::Lighting::getEffectiveLightName ( RenderNamespace::glsl &  lightshader, unsigned  LightNr  )

static

Convenience function for a text replacement operation:

Substitute any occurance of the placeholde in the given lightshader with the light number.

postfix()

RenderNamespace::glsl Wizt::RenderNamespace::Lighting::postfix ( unsigned  NumberOfLightSources )

static

Define a global function.

vec3    getLightAtVertex(vec3 vertex)

which computes the sum of calling all defined light functions.
