WebDescription. smoothstep () performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1. This is useful in cases where a threshold function with a smooth transition is desired. smoothstep () is equivalent to: genType t; /* Or genDType t; */ t = clamp ( (x - edge0) / (edge1 - edge0), 0.0, 1.0 ); return t * t * ( 3.0 - 2.0 * t); Web19 ago 2024 · This function uses the following formula: ( x >= y) ? 1 : 0.
