## Detailed Description

template<typename MapType, DDScheme DiffScheme2, DScheme DiffScheme1>
struct openvdb::v10_0::math::MeanCurvature< MapType, DiffScheme2, DiffScheme1 >

Compute the mean curvature.

The mean curvature is returned in two parts, alpha and beta, where alpha is the numerator in ∇ · (∇Φ / |∇Φ|) and beta is |∇Φ|.

## compute() [1/2]

template<typename MapType, DDScheme DiffScheme2, DScheme DiffScheme1>
template<typename Accessor>

bool compute | ( | const MapType & | map,
|  | const Accessor & | grid,
|  | const Coord & | ijk,
|  | double & | alpha,
|  | double & | beta )

inline static

Random access version.

Returns
  `true` if the gradient is nonzero, in which case the mean curvature is returned in two parts, alpha and beta, where alpha is the numerator in ∇ · (∇Φ / |∇Φ|) and beta is |∇Φ|.

## compute() [2/2]

template<typename MapType, DDScheme DiffScheme2, DScheme DiffScheme1>
template<typename StencilT>

bool compute | ( | const MapType & | map,

|  | double & | alpha,
|  | double & | beta )

inline static

Stencil access version.

Returns
  `true` if the gradient is nonzero, in which case the mean curvature is returned in two parts, alpha and beta, where alpha is the numerator in ∇ · (∇Φ / |∇Φ|) and beta is |∇Φ|.
