detail::fvec4SIMD glm::mix(const detail::fvec4SIMD &x, const detail::fvec4SIMD &y, const detail::fvec4SIMD &a)
Documentation from code comments
\return If genTypeU is a floating scalar or vector: Returns x * (1.0 - a) + y * a, i.e., the linear blend of x and y using the floating-point value a. The value for a is not restricted to the range [0, 1].
\return If genTypeU is a boolean scalar or vector: Selects which vector each returned component comes from. For a component of a that is false, the corresponding component of x is returned. For a component of a that is true, the corresponding component of y is returned. Components of x and y that are not selected are allowed to be invalid floating point values and will have no effect on the results. Thus, this provides different functionality than genType mix(genType x, genType y, genType(a)) where a is a Boolean vector.
From GLSL 1.30.08 specification, section 8.3
\param[in] x Floating point scalar or vector. \param[in] y Floating point scalar or vector. \param[in] a Floating point or boolean scalar or vector.
\todo Test when 'a' is a boolean.

Returns 0.0 if x <= edge0 and 1.0 if x >= edge1 and performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1. This is useful in cases where you would want a threshold function with a smooth transition. This is equivalent to: genType t; t = clamp ((x - edge0) / (edge1 - edge0), 0, 1); return t * t * (3 - 2 * t); Results are undefined if edge0 >= edge1.
