Craters generation
-------------------------------------------------------------------------------------
- added "successive-impacts" flag;
- perturbation applied following the vertex normal and not the crater centre normal,
in order to "follow" the mesh surface;
- added "smoothing steps" parameter to pre-smooth vertex normals a given number of times
before generating craters;
- added "elevation" parameter to decide the fraction of depth that will rise from mesh surface;
- added blending algorithm to blend the above elevation towards the original mesh surface;
the blending is supported by two new parameters:
- blending algorithm: defines the blending functions (there are four blending functions
available so far: exponential blending, linear blending, gaussian blending and f3 blending);
- blending threshold: defines the fraction of radius above which the radial function is
replaced by the blending function.
- removed "profile factor" parameter;
- filter description modified.
Code modifications: now the noise, radial and blending functions are defined as functors,
and the crater functor is basically a combination of a radial functor, a blending functor
and a noise functor (for postprocessing noise). All these functors work with normalized
inputs and returns normalized output; they are all implemented in the new filter_functors.h
file.
More to come: code cleanings, reorganizations and comments.
