Member Function Documentation

◆ compute_distance_to_surface()

void OGF::VoxelGrobAttributesCommands::compute_distance_to_surface	(	const MeshGrobName &	surface,
		const std::string &	attribute = `"distance"`,
		bool	signed_dist = `false`
	)

Computes the distance between each vertex and a surface.

Parameters

[in]	surface	the surface
[in]	attribute	the name of the vertex attribute
[in]	signed_dist	if true, computes the signed distance (needs the input shape to be tetrahedralized)

◆ delete_attribute()

void OGF::VoxelGrobAttributesCommands::delete_attribute ( const std::string & name )

Deletes an attribute.

Parameters

[in] name the name of the attribute

◆ load_attribute()

void OGF::VoxelGrobAttributesCommands::load_attribute	(	const std::string &	attribute,
		const FileName &	filename
	)

Loads an attribute for a 32 bit floating point raw file.

Parameters

[in] filename a binary file with the attribute stored as single-precision floats.

◆ normalize_attribute()

void OGF::VoxelGrobAttributesCommands::normalize_attribute	(	const std::string &	name,
		float	min_val = `0.0`,
		float	max_val = `1.0`
	)

Normalizes a floating-point attribute.

Parameters

[in]	name	the name of the attribute
[in]	min_val	the minimum value
[in]	max_val	the maximum value

◆ Poisson_reconstruction()

void OGF::VoxelGrobAttributesCommands::Poisson_reconstruction	(	const MeshGrobName &	points,
		const std::string &	attribute = `"distance"`,
		index_t	depth = `8`,

	)

Reconstructs a surface from points and normals using Misha Kahzdan's Screened Poisson Reconstruction.

Parameters

[in]	points	the name of the object that stores the points. It needs to have a "normal" attribute.
[in]	attribute	the name of the attribute used to store the reconstructed implicit function.
[in]	depth	the depth of the octree, 8 is the default value, use 10 or 11 for highly detailed models
[in]	reconstruction	(optional) the name of the reconstructed surface
