	Evaluate the polynomial smooth minimum.

Detailed Description

template<class T>
struct EBGeometry::SmoothMinOp< T >

Quadratic polynomial smooth minimum for blending two signed-distance values.

Approximates min(a, b) within the overlap region |a - b| < s; coincides exactly with min(a, b) outside that region. Cheaper to evaluate than ExpMinOp and the default choice for CSG unions. A trivially copyable function object, so it can be stored in a BVHSmoothUnion and evaluated on a device.

Template Parameters

T	Floating-point precision.

Member Function Documentation

operator()()

template<class T >

T EBGeometry::SmoothMinOp< T >::operator() ( const T &  a, const T &  b, const T &  s  ) const

inlinenoexcept

Evaluate the polynomial smooth minimum.

Parameters

[in]	a	First value.
[in]	b	Second value.
[in]	s	Smoothing length (must be > 0). Controls the blend region width.

Returns

Polynomial-blended approximation of min(a, b).
