[FR] Add step and smoothstep functions #75
Description
... so they can be used with shady.
Here are implementations for float (after the example here). Should be relatively easy to make them generic:
proc step*(a, x: float): float =
if x < a:
0.0
else:
1.0
proc smoothstep*(a, b, x: float): float =
# Scale, and clamp x to 0..1 range
let x = clamp((x - a) / (b - a), 0.0, 1.0)
x * x * (3.0 - 2.0 * x)Then update shady to add these functions to glslFunctions.
