Glsl smoothstep performance

WebJust like GLSL ES 3.0, implicit casting between scalars and vectors of the same size but different type is not allowed. Casting of types of different size is also not allowed. Conversion must be done explicitly via constructors. Example: float a = 2; // valid float a = 2.0; // valid float a = float(2); // valid. WebJun 10, 2013 · Lerp (A, B, C); Lerp: Linear interpolation between values A and B, using the floating position C. SmoothStep (A, B, C); SmoothStep: Returns a value from 0 to 1, compared between minimum value A and maximum B, using the value C. In some cases you can use them similarly, smoothstep only having a more slope-like-curve.
