Description

Attach this visual asset to a ChPhysicsItem (ex.a ChDomain) in order to provide an automatic visualization of Gauss material points and finite element nodes, as 3D glyps (arrows, dots, etc.).

If the visualization system supports glyphs, these will be rendered (ex. in Irrlicht 3d view, but also in Blender postprocessing etc. The system is modular and expandable, so that you can visualize properties such as stress, strain, speed, acceleration, temperature etc., by adding ChVisualDataExtractor objects to this visual asset.

		double	min = `0`,
		double	max = `1`,
		std::string	mname = `"Matr"`
	)

inline

Attach 3x3 matrix property extractor.

Also turns the glyph rendering into ChGlyph::GLYPH_TENSOR mode. If you added more than one property via AddPropertyExtractor(), by default the last one will be used for the falsecolor rendering.

◆ AddPropertyExtractor() [2/3]

void chrono::fea::ChVisualDomainGlyphs::AddPropertyExtractor	(	const ChVisualDataExtractorScalarBase &	mextractor,
		double	min = `0`,
		double	max = `1`,
		std::string	mname = `"Scalar"`
	)

inline

Attach scalar property extractor.

Also turns the glyph rendering into ChGlyph::GLYPH_POINT mode. If you added more than one property via AddPropertyExtractor(), by default the last one will be used for the falsecolor rendering.

◆ AddPropertyExtractor() [3/3]

void chrono::fea::ChVisualDomainGlyphs::AddPropertyExtractor	(	const ChVisualDataExtractorVectorBase &	mextractor,
		double	min = `0`,
		double	max = `1`,
		std::string	mname = `"Vect"`
	)

inline

Attach vector property extractor.

Also turns the glyph rendering into ChGlyph::GLYPH_POINT mode. If you added more than one property via AddPropertyExtractor(), by default the last one will be used for the falsecolor rendering.

◆ SetColormap()

void chrono::fea::ChVisualDomainGlyphs::SetColormap ( const ChColor & col )

inline

Set the color for rendering the glyphs as constant uniform color.

This disables the colormap falsecolor rendering.

◆ Update()

virtual void chrono::fea::ChVisualDomainGlyphs::Update	(	ChObj *	updater,
		const ChFrame<> &	frame
	)

inlineoverrideprotectedvirtual

This Update() is called automatically by the parent ChPhysicsItem all time that the system needs to update the visual assets.

The main task of this Update is to generate/update the lists of glyps (vectors, poionts, etc.) that represents the visualization of the nodes and material points of the domain.

Reimplemented from chrono::ChVisualShape.
