A SDF gives the distance between a point in space and a surface, with negative values meaning the point is inside the object. -To trace a ray in a certain direction, we can take the minimum of all SDFs in the scene and move by that amount in that direction. We can now repeat this process until the smallest distance is zero (or very close to it). +In ray marching, every object is defined by a so called **signed distance funtion**, SDF for short.

We can now repeat this process until the smallest distance is zero (or very close to it). Like all ray tracing algorithms, ray marching allows for very realistic lighting simulations. ## Features -The engine is currently a WIP and new features are added with almost every commit. +The engine is currently a WIP and new features are added with almost every commit.
