Function Documentation

createVoxelFromLayeredMesh()

std::unique_ptr< MeshLib::Mesh > MeshToolsLib::MeshGenerators::VoxelFromLayeredMeshes::createVoxelFromLayeredMesh	(	std::pair< MathLib::Point3d, MathLib::Point3d > &	extent,
		std::vector< MeshLib::Mesh const * > const &	layers,
		std::array< double, 3 > const	cellsize,
		bool const	dilate )

Constructs a VoxelGrid with a specified resolution of a list of layered meshes.

Parameters

extent	The axis-aligned boundary-box (AABB) which is initially defined.
layers	Containing all the meshes that will be used to create the VoxelGrid.
cellsize	Contains the resolution of the Voxel (i.e. length in x-,y-,z-directions)
dilate	A flag to set dilate. If dilate is True all Voxels which are not fully covered by the meshes are included in the resulting VoxelGrid.
