Detailed Description

Fast winding number computation for triangle soups.

Constructor & Destructor Documentation

FastWindingNumber() [1/3]

FastWindingNumber

(

const SurfaceMesh< Scalar, Index > &

mesh

)

Constructs an acceleration structure on a given mesh to speed up winding number queries.

Note

Internally, point coordinates are converted to float and vertex indices are converted to int.

Parameters

[in]

mesh

Triangle mesh used to initialize the fast winding number acceleration structure.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.

FastWindingNumber() [2/3]

FastWindingNumber ( FastWindingNumber &&  other )

defaultnoexcept

Constructs a new instance.

Parameters

other

Instance to move from.

FastWindingNumber() [3/3]

FastWindingNumber ( const FastWindingNumber &  other )

delete

Constructs a new instance.

Parameters

[in]

other

Instance to copy from.

Member Function Documentation

operator=() [1/2]

FastWindingNumber & operator= ( FastWindingNumber &&  other )

defaultnoexcept

Assignment operator.

Parameters

other

Instance to move from.

Returns

The result of the assignment.

operator=() [2/2]

FastWindingNumber & operator= ( const FastWindingNumber &  other )

delete

Assignment operator.

Parameters

[in]

other

Instance to copy from.

Returns

The result of the assignment.

is_inside()

bool is_inside

(

const std::array< float, 3 > &

pos

)

const

Determines whether the specified query point is inside the volume.

Parameters

[in]

pos

Query position.

Returns

True if the specified point is inside, False otherwise.

solid_angle()

float solid_angle

(

const std::array< float, 3 > &

pos

)

const

Computes the solid angle at the query point.

Parameters

[in]

pos

Query position.

Returns

Solid angle at the query point.
