imstk::SurfaceMeshDistanceTransform Class Reference

This filter computes exact signed distance fields using octrees and pseudonormal computations. One might need to adjust the tolerance depending on dataset scale. The bounds for the image can be set in the filter, when none are set the bounding box of the mesh is used, the margin. When providing your own bounds a box larger than the original object might be necessary depending on shape. More...

Detailed Description

This filter computes exact signed distance fields using octrees and pseudonormal computations. One might need to adjust the tolerance depending on dataset scale. The bounds for the image can be set in the filter, when none are set the bounding box of the mesh is used, the margin. When providing your own bounds a box larger than the original object might be necessary depending on shape.

setBounds()

void imstk::SurfaceMeshDistanceTransform::setBounds	(	const Vec3d &	min,
		const Vec3d &	max
	)

Optionally one may specify bounds, if not specified bounds of the input SurfaceMesh is used.

note Vec6d is be of the format [minX, maxX, minY, maxY, minZ, maxZ]
