Detailed Description

Syntactic sugar to ease coupling of uniform shader parameters with TypedSlots and functions.

This works by coupling the Anemone::updateValues(VRenderContext&Context) function with the context-relative evaluation of a TypedSlot.

Function Documentation

operator<<() [1/11]

template<int M, typename T >

MemCore::WeakPtr< VRenderContext::RenderParameter > Wizt::operator<< ( const Anemone_Context_String_t &  ACS, const Eagle::FixedArray< T, M > &  Value  )

inline

Set a constant value as render parameter.

Anemone << Context << "shader_variable" << 3.0;

operator<<() [2/11]

template<class Type >

Anemone_Context_Parameter_t Wizt::operator<< ( const Anemone_Context_String_t &  Target, const TypedSlot< Type > &  InputSlot  )

inline

Couple a uniform variable with an object's input slot using and the name of the shader variable must be identical to the name of the input slot.

This allows for code such as:

RenderAnemone << Context << "MyColor" << inColor;

where inColor is an object's input

in<Color>    inColor;

operator<<() [3/11]

template<class Type >

Anemone_Context_Parameter_t Wizt::operator<< ( const Anemone_Context_String_t &  Target, const VObject::in< Type > &  InputSlot  )

inline

Couple a uniform variable with an object's input slot using the name of the input slot.

This allows for a syntax such as:

RenderAnemone << Context << "color" << inColor;

where inColor is an object's input

in<Color>    inColor;

operator<<() [4/11]

template<class Type >

Anemone_Context_Parameter_t Wizt::operator<< ( const Anemone_Context_String_t &  Target, const VObject::inout< Type > &  InputSlot  )

inline

Couple a uniform variable with an object's input slot using the name of the input slot.

This allows for a syntax such as:

RenderAnemone << Context << "color" << inColor;

where inColor is an object's input

inout<Color> inColor;

operator<<() [5/11]

template<class Type >

Anemone_Context_Parameter_t Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext & > &  Target, const TypedSlot< Type > &  InputSlot  )

inline

Couple a uniform variable with an object's input slot using the name of the input slot.

This allows for a syntax such as:

RenderAnemone << Context << inColor;

where inColor is an object's input

in<Color>    inColor;

and the name of the shader variable must be identical to the name of the input slot.

Alternatively a name of the shader variable can be specified explictly:

RenderAnemone << Context << "MyColor" <<inColor;

operator<<() [6/11]

template<class Type , class Modifier >

MemCore::WeakPtr< VRenderContext::RenderParameter > Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext &, std::string, Modifier > &  Target, const TypedSlot< Type > &  InputSlot  )

inline

Couple a Vish Object's input slot with a uniform shader variable via some functor, allowing for the following syntax:

RenderAnemone << Context << "glPolygonMode" << &PolygonMode << inOptions;

whereas PolygonMode is a functor, for instance a function:

        TypedSlot<Options>              inOptions;
 
static  int     PolygonMode(const Options&Op)
        {
                if (Op("wireframe")) return 1;
                else                 return 2;
        }

The functor's return type must correspond to the uniform shader variable, the functor's parameter must correspond to the input slot's type.

operator<<() [7/11]

template<class Object , class ParameterType >

const std::tuple< Anemone &, VRenderContext &, std::string, ParameterType(Object::*)(const ParameterType &, VRenderContext &Context) const, const Object * > Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext &, std::string, ParameterType(Object::*)(const ParameterType &, VRenderContext &Context) const > &  Target, const Object *  theObject  )

inline

Couple an Anemone's updateValues() function with an VObject's member function.

Application code looks like this

RenderAnemone << Context << "glLineWidth" << &DisplayLines::adjustLineWidth << this << 5.0;

whereas

operator<<() [8/11]

template<class Object , class ParameterType >

MemCore::WeakPtr< VRenderContext::RenderParameter > Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext &, std::string, ParameterType(Object::*)(const ParameterType &, VRenderContext &Context) const, const Object * > &  Target, const ParameterType &  Value  )

inline

Couple an Anemone's updateValues() function with an VObject's member function.

Application code looks like this

RenderAnemone << Context << "glLineWidth" << &DisplayLines::adjustLineWidth << this << 5.0;

whereas

double        DisplayLines::adjustLineWidth(const double&Value, VRenderContext&Context) const;

operator<<() [9/11]

template<class Object , class ParameterType , class Type >

inline

Couple an Anemone's updateValues() function with an VObject's member function via a modifier function on a slot.

RenderAnemone << Context << "glLineWidth" << &DisplayLines::adjustLineWidth << this << 5.0;

whereas

double       DisplayLines::adjustLineWidth(const double&Value, VRenderContext&Context) const;

operator<<() [10/11]

template<class Object , class ParameterType , class Type >

MemCore::WeakPtr< VRenderContext::RenderParameter > Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext &, std::string, ParameterType(Object::*)(const Type &, VRenderContext &Context) const, const Object * > &  Target, const VObject::inout< Type > &  InputSlot  )

inline

Couple an Anemone's updateValues() function with an VObject's member function via a modifier function on a slot.

RenderAnemone << Context << "glLineWidth" << &DisplayLines::adjustLineWidth << this << 5.0;

whereas

double       DisplayLines::adjustLineWidth(const double&Value, VRenderContext&Context) const;

operator<<() [11/11]

template<class Object , class ParameterType >

MemCore::WeakPtr< VRenderContext::RenderParameter > Wizt::operator<< ( const std::tuple< Anemone &, VRenderContext &, std::string, ParameterType(Object::*)(VRenderContext &Context) const > &  Target, const Object *  theObject  )

inline

Couple an Anemone's updateValues() function with an VObject's member function.

Application code looks like this

RenderAnemone << ARC << "ColormapDataMax" << &DisplayFlatTriangles::setColormapDataMax << this;

whereas

double       DisplayFlatTriangles::setColormapDataMin(VRenderContext&Context) const;

operator>>()

template<typename Type >

MemCore::RefPtr< RenderBasin::RenderParameter > Wizt::operator>> ( const Anemone_Context_String_t &  ACS, const Type &  Functor  )

inline

Couple an Anemone's updateValues() function with functor, in particular a lambda function:

RenderAnemone << Context << "Observer" >>
                [](const VRenderContext&C) { return C.CameraSettings.Observer; };

Note the special syntax >> used here. If "<<" is used, then it will try to set a constant value of type lambda, which fails.
