Detailed Description

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

Makes use of DrawElements();

Constructor & Destructor Documentation

◆ ElementRenderer()

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.

Member Function Documentation

◆ draw()

bool GL::ElementRenderer::draw ( )

overridevirtual

The actual draw function.

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

Implements Wizt::VBO::Renderer.

Reimplemented in Wizt::SplatRenderObject::Renderer.

References CurrentIBO.

Referenced by Wizt::SplatRenderObject::Renderer::draw().

◆ sortByDepth()

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

Todo: Add memory management
