UnverifiedSphere tracing is a classical algorithm for rendering implicit surfaces that advances along a ray by the safe step length indicated by the SDF value at the current point, iterating until the distance is close enough to zero to be considered a hit.61% similarUnverifiedThe offset-distance property determines the distance an element moves along the path, taking a percentage or length value, where 0% represents the start of the path and 100% represents the end.56% similar
