Detailed Description

Base class for objects that render information given on a Grid.

The grid that is used for rendering might stem from a Field selection or a Grid selection.

Child classes need to implement the virtual function

virtual GridSelector getGridSelector(const RefPtr<ValuePool>&Context);

Eagle::Context

Fiber::CreativeIterator

An iterator with an optional DataCreator, which is just a class to intercept creation of data along a...

Definition CreativeIterator.hpp:34

Fiber::GridSelector

Context information to select a grid from within a bundle.

Definition GridSelector.hpp:26

to specify the source of the grid.

Recipe for implementing child classes:

Implement validateInput() to check for additional constraints on the input parameters, and possibly extract some more information.
Anything computationally intensive needs to be done in the update() function, from which validateInput() is called as well. It has to provide its results and pass it to the render() function via the local state object. Child classes need to derive from GridAnemoneState to extent it by additional information and implement the newState() function to return such derived state objects.
Let isValidAnemone() return false for the development stage such that no caching occurs and full concentration can be given on creating an appropriate rendering object.
Implement updateAnemone() such to read the required data ONLY from the state object and to appropriately extend the provided Anemone object for rendering. This includes in particular inserting a Painter Tentacle. At this point, the coordinates of the Grid object for a given fragment will already be available.
Deal with caching issues by properly implementing the updateAnemone() and isValidAnemone() functions.

◆ addSupplementaryData()

bool Wizt::GridAnemone::addSupplementaryData	(	VRequest &	Context,
		Fiber::Info< Fiber::Grid > &	,
		RenderFields &	RF,
		const RefPtr< Fiber::Skeleton > &	myVertexSkeleton,
		const RefPtr< Fiber::Chart > &	chart,
		string &	InfoString
	)

virtual

Virtual call to add additional data in child classes.

Note that the vertex skeleton and the chart are contained in the GridAnemoneState at this point.

Parameters

InfoString The status info string that can optionally be modified.

Reimplemented in Wizt::FieldAnemone.

Referenced by update().

◆ do_feedback_render()

TouchIndex_t Wizt::GridAnemone::do_feedback_render	(	VRenderContext &	Context,
		TouchIndex_t	StartIndex
	)		const

Support for feedback rendering, in case a child object is derived from a Touchable.

The child object still needs to implement VTouchable::feedback_render(), which will trivially call this function.

◆ environment_render()

bool Wizt::GridAnemone::environment_render ( VRenderContext & Context ) const

overridevirtual

Implements Wizt::RenderAble.

◆ getLastRenderTime()

RenderAble::RenderTime Wizt::GridAnemone::getLastRenderTime ( VRenderContext & Context ) const

overridevirtual

Reimplemented from Wizt::RenderAble.

◆ getRenderFields()

GridAnemone::FieldHierarchy Wizt::GridAnemone::getRenderFields ( VRenderContext & Context ) const

virtual

Get the primary field that will be used for rendering.

This field will in general be a Positions field, in many cases of the vertices of a grid in cartesian coordinates. It may also stem from a higher order topology of a grid, for instance the triangle cells of a mesh.

The render Anemones will be cached at each fragment of this field relative to this object and relative to the given Context.

◆ getTouchableBoundingBall()

RefPtr< BoundingBall > Wizt::GridAnemone::getTouchableBoundingBall ( const RefPtr< ValuePool > & VP ) const

overridevirtual

Get the bounding box of the entire object's geometry beyond the visible part such to allow proper camera navigation.

Reimplemented from Wizt::RenderAble.

Reimplemented in Wizt::PictureBase.

References Fiber::GridSelector::findMostRecentGrid(), Wizt::VRenderObject::getBoundingBall(), Fiber::GridSelector::getBundle(), and getCartesianChart().

◆ initializeAnemone()

virtual AnemoneRenderStatus Wizt::GridAnemone::initializeAnemone	(	Anemone &	RenderAnemone,
		const AnemoneCreationContext &	ARC,
		const RefPtr< AnemoneExplorer > &	AE
	)		const

pure virtual

       Initialize a virgin Render Anemone, i.e. equip it with all its properties as
       required for rendering (aka waving).

       Note: Must always clear the anemone before calling initialize() since all operations here will APPEND.

       Render parameters (uniform shader variables) can be connected to be updated automatically
       from an input slot.
       Given the name of an uniform variable and the input slot

in<rgba_float_t> inColor;

then the this slot can be bound to the shader's uniform variable via

RenderAnemone << ARC << "MonochromeColor" << inColor;

Implemented in Wizt::FieldAnemone.

◆ isCreatingSupplementaryData()

bool Wizt::GridAnemone::isCreatingSupplementaryData	(	VRenderContext &	theContext,
		const RefPtr< Fiber::FragmentID > &	myFragmentID
	)		const

virtual

Asynchroneous mode: Check whether supplementary data are currently under creation.

Asynchrone mode: Check whether supplementary data are currently under creation.

Reimplemented in Wizt::FieldAnemone.

◆ isValidAnemone()

bool Wizt::GridAnemone::isValidAnemone	(	const Anemone &	RenderAnemone,
		const AnemoneCreationContext &	ARC,
		const RefPtr< AnemoneExplorer > &	AE
	)		const

virtual

Checks if a given Anemone is valid for rendering.

Consider the case that some anemone may be reused, but unfortunately is invalid for whatever reason. This may happen if it was created incomplete previously, but nothing has changed since then, so it's still invalid, even though it could be reused...

Any code derive from Programmable may just call

return hasValidShaderPrograms(RenderAnemone, ARC.myContext);

to check for validity of the attached shader programs.

Reimplemented in Wizt::FieldAnemone, and Wizt::PictureBase.

◆ newAnemoneCreator()

RefPtr< AnemoneCreatorBase > Wizt::GridAnemone::newAnemoneCreator ( const Seagrass & theSeaggrass ) const

virtual

If some parameters of a Render Anemone need to be modified upon change of some input, for instance some uniform shader variables, then re-creation of the entire Anemone is overkill.

References to those parameters can then be stored at its AnemoneCreator, which will be destroyed as soon as the data generating the Render Anemone are destroyed as well.

struct  MyAnenomeCreator : AnemoneCreator<>
{
        WeakPtr<RenderBasin::RenderParameter>   ColorParameter;
        WeakPtr<RenderBasin::RenderParameter>   ShininessParameter;
 
        MyAnenomeCreator(const Seagrass&theSeagrass)
        : AnemoneCreator<>(theSeagrass)
        {}
};
 
 
RefPtr<AnemoneCreatorBase> newAnemoneCreator(const Seagrass&theSeagrass) const
{
        return new MyAnenomeCreator(theSeagrass);
}

A derived class may then implement modifying the rendering parameters:

bool    updateAnemone   (const Anemone&RenderAnemone,
                         const AnemoneCreationContext&ARC,
                         const RefPtr<AnemoneExplorer>&AE) const override
{
RefPtr<MyAnenomeCreator> S = ARC.myAnemoneCreator;
        if (!S)
                return false;
 
rgba_float_t color(0.6, 0.7, 0.9, 1.0);
        if (S->ColorParameter)
                S->ColorParameter->modify(color);
 
        return true;
}

Note that this code example examplifies "manual" updating of a render parameter (i.e., a uniform shader variable). The more convenient way, if possible, is to set a connection from an input slot to a render parameter, see initializeAnemone().

◆ newState()

RefPtr< GridAnemone::State > Wizt::GridAnemone::newState ( ) const

overridevirtual

Reimplemented from Wizt::VStateCreatorBase.

◆ raiseAnemone()

GridAnemone::AnemoneRenderStatus Wizt::GridAnemone::raiseAnemone	(	Anemone &	RenderAnemone,
		const AnemoneCreationContext &	ARC,
		const RefPtr< AnemoneExplorer > &	AE
	)		const

Function to pack all kinds of information into a baby Anemone to let it grow into an adult functional one.

Calls the virtual initializeAnemone() function at some point.

◆ requestSupplementaryData()

void Wizt::GridAnemone::requestSupplementaryData	(	VRenderContext &	theContext,
		const RefPtr< Fiber::FragmentID > &	myFragmentID
	)		const

virtual

Asynchroneous mode: Request creation of supplementary data.

Reimplemented in Wizt::FieldAnemone.

◆ update()

bool Wizt::GridAnemone::update	(	VRequest &	R,
		double	precision
	)

overridevirtual

The update function retrieves data from the input Grid and prepares them in the State object for rendering.

Reimplemented from Wizt::VObject.

◆ updateAnemone()

bool Wizt::GridAnemone::updateAnemone	(	Anemone &	RenderAnemone,
		const AnemoneCreationContext &	ARC,
		const RefPtr< AnemoneExplorer > &	AE
	)		const

virtual

Update a certain Anemone with variables and values that do not require re-creation or loading of any data.

If this function returns false, then this Anemone will not be rendered but destroyed. If this function returns true, but the Anemone is empty(), then it will be re-initialized.

Reimplemented in Wizt::PictureBase.

◆ validateInput()

bool Wizt::GridAnemone::validateInput	(	VRequest &	Context,
		Fiber::Info< Fiber::Grid > &	,
		const RefPtrGridAnemoneState &	GAS,
		const RefPtr< Fiber::Skeleton > &	myVertexSkeleton,
		const RefPtr< Fiber::Chart > &	chart,
		string &	ValidateInputInfoString
	)		const

virtual

Virtual call to check if the information retrieved from the inputs is valid, and if further information as required by the child class as been added correctly.

This function needs to set the object status message if returning false, for instance:

if (bad_condition)
{
     setStatusError(Context, "Something bad happened");
     return false;
}
