Member Function Documentation

decode()

static Index EBGeometry::SFC::Morton::decode ( const uint64_t &  a_code )

inlinestaticnoexcept

Decode the 64-bit Morton code into an Index.

Parameters

[in]

a_code

Morton code to decode. Must be a code actually produced by encode(), i.e. no bits above position 3*ValidBits-1 may be set.

Returns

3D grid index corresponding to a_code.

encode()

static uint64_t EBGeometry::SFC::Morton::encode ( const Index &  a_point )

inlinestaticnoexcept

Encode an input point into a Morton index with a 64-bit representation.

Parameters

[in]

a_point

3D grid index to encode. Each component must be <= ValidSpan.

Returns

64-bit Morton code for a_point.
