Function Documentation

MeshSphericalDecomposition()

template<typename Real >

std::vector<ChVector<Real> > chrono::gpu::MeshSphericalDecomposition	(	std::string	objfilename,
		ChVector< Real >	scaling,
		ChVector< Real >	offset,
		Real	sphere_radius
	)

Decompose a given triangle mesh surface into a minimally-overlapping collection of spheres.

The mesh must be stored in OBJ format and must consist of only triangles. Returns the number of spheres added as a result of the decomposition.

Parameters

objfilename	OBJ mesh file path
scaling	Scaling vector to apply to the mesh before decomposition
offset	Displacement to apply to the mesh before decomposition
sphere_radius	Radius to use for all spheres in the decomposition

ParseJSON()

bool chrono::gpu::ParseJSON	(	const std::string &	json_file,
		ChGpuSimulationParameters &	params,
		bool	verbose = true
	)

Parse the specified JSON file with simulation settings.

Returns true on successful parameter load. Returns false and prints error on invalid argument.
