Webb27 feb. 2024 · The way you're raymarching assumes that map is a true distance function, or at least a conservative one: because you try to step forward by the distance returned by map in each iteration, that return value must always be less than or equal to the true distance to your surface. But your addition of sine breaks that rule.
