UndercutMetric

using MR::FixUndercuts::UndercutMetric = std::function<double( const FaceBitSet&, const FindParams& params )>

Function Documentation

distMapImproveDirection()

MRVOXELS_API Vector3f MR::FixUndercuts::distMapImproveDirection ( const Mesh & mesh, const DistMapImproveDirectionParameters & params )

nodiscard

Score candidates with distance maps, lower resolution -> faster score

Note

does not support wallAngle yet

find() [1/2]

MRVOXELS_API double MR::FixUndercuts::find	(	const Mesh &	mesh,
		const FindParams &	params,
		FaceBitSet &	outUndercuts,
		const UndercutMetric &	metric = {} )

Adds undercuts to

Parameters

outUndercuts

if metric is set returns metric of found undercuts, otherwise returns DBL_MAX

fix()

MRVOXELS_API Expected< void > MR::FixUndercuts::fix	(	Mesh &	mesh,
		const FixParams &	params )

Fixes undercut areas by building vertical walls under it, algorithm is performed in voxel space, so the mesh is completely rebuilt after this operation

fixUndercuts() [1/2]

MRVOXELS_API MR_BIND_IGNORE Expected< void > MR::FixUndercuts::fixUndercuts	(	Mesh &	mesh,
		const FaceBitSet &	selectedArea,
		const Vector3f &	upDirection,
		float	voxelSize = 0.0f,
		float	bottomExtension = 0.0f )

		const Vector3f &	upDirection,
		float	voxelSize = 0.0f,
		float	bottomExtension = 0.0f )

getUndercutAreaMetric()

MRVOXELS_API UndercutMetric MR::FixUndercuts::getUndercutAreaMetric ( const Mesh & mesh )

nodiscard

scoreUndercuts()

MRVOXELS_API double MR::FixUndercuts::scoreUndercuts ( const Mesh & mesh, const Vector3f & upDirection, const Vector2i & resolution )

nodiscard

Fast score undercuts projected area via distance map with given resolution lower resolution means lower precision, but faster work

Note

does not support wallAngle yet
