Public Types

typedef MemCore::RefPtr
< Wizt::IndexBufferObject > IBO_t
An index buffer object.
typedef Fiber::MemArray< 3, IBO_t > ViewBufferArray_t
Type to be used for storing index arrays for view-dependent rendering via depth-sorting.

Public Member Functions

IBO_t sortByDepth (Wizt::VRenderContext &Context, const MemCore::RefPtr< Fiber::CreativeArrayBase > &VertexCoordinates, unsigned Discretization=2)
ElementRenderer (const MemCore::RefPtr< Fiber::MemBase > &FieldCoordinates, const MemCore::RefPtr< Fiber::FragmentSelector > &FS)
Construct a partial element renderer by giving an array of coordinates and a fragment selector.
~ElementRenderer ()
Destructor, does nothing particular.
override bool draw ()
The actual draw function.

MemCore::RefPtr
< ViewBufferArray_t > SortedIndices
Storage of view-dependent index arrays.
IBO_t CurrentIBO
Index Buffer Object that is supposed to be used.
MemCore::RefPtr< ElementSorter > MyElementSorter
GLenum draw_mode
GLsizei count

Base class to draw a selection of elements as OpenGL points.

Makes use of DrawElements();

Examples:: CrystalSurface.cpp, EvolutionSurface.cpp, TransparentColoredSurface.cpp, and TransparentSurface.cpp.

GL::ElementRenderer::ElementRenderer	(	const MemCore::RefPtr< Fiber::MemBase > &	FieldCoordinates,
		const MemCore::RefPtr< Fiber::FragmentSelector > &	FS
	)

Construct a partial element renderer by giving an array of coordinates and a fragment selector.

If the fragment selector is given, it will create a set of indices here. This is a possibly slow operation.

bool GL::ElementRenderer::draw ( ) [virtual]

The actual draw function.

If a CurrentIBO is set, it will use this one, otherwise will draw all elements.

IBO_t GL::ElementRenderer::sortByDepth	(	Wizt::VRenderContext &	Context,
		const MemCore::RefPtr< Fiber::CreativeArrayBase > &	VertexCoordinates,
		unsigned	Discretization = `2`
