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
objfilenameOBJ mesh file path
scalingScaling vector to apply to the mesh before decomposition
offsetDisplacement to apply to the mesh before decomposition
sphere_radiusRadius to use for all spheres in the decomposition

◆ ParseJSON()

bool chrono::gpu::ParseJSON ( const char *  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.
