Dependency of the camera tilt angle on the style zoom level, if the dependency could not be created - throw an exception.

The dependency must be a monotonic continuous function. If a dependency that does not satisfy the conditions is specified by the points, then the function throws an exception . A dependency, similar to 2GIS, can be specified by a sequence of points 17,0,19,15,20,25 in map mode and 15,0,16,34,17,48 in navigator mode. Let's get the camera tilt angle T for the Z style zoom level, so that Z0 < = Z < Z1 and dependency is given by the points Z0,T0,Z1,T1. Then the desired value is calculated by the formula T = T0 + k * (T1 - T0), where k = (Z - Z0) / (Z1 - Z0).If Z < Z0, then T = T0. If Z >= Z1, then T = T1.
