Computation :: Parametric Functions

bias(b, x): Returns the given value with a bias function applied to it.

boxstep(a, b, x): Returns 0 when (x <= a), 1 when (x >= b), a linear transition from 0 to 1 when (a < x < b), or (-1) on error (a == b).

gain(g, x): Returns the given value with a gain function applied to it.

gammacorrect(gamma, x): Returns the given value with gamma correction applied to it.

map_range(x, a1, a2, b1, b2): Returns a value remapped from one range to another.

pulse(a, b, x): Returns 1 when (a <= x <= b), 0 otherwise.

smoothstep(a, b, x): Returns 0 when (x <= a), 1 when (x >= b), a smooth transition from 0 to 1 otherwise.

spline(t, knotlist): Returns the Catmull-Rom interpolation of the given knot values at the given parameter position.

spline4(t, knot1, knot2, knot3, knot4): Returns the Catmull-Rom interpolation of the given knot values at the given parameter position.

step(a, x): Returns 0 when (x < a), 1 otherwise.
