Description Usage Arguments Details
Search for most interesting projection along random geodesics.
1 | search_geodesic(current, alpha=1, index, max.tries=5, n=5)
|
current |
starting projection |
alpha |
maximum distance to travel (currently ignored) |
index |
interestingness index function |
max.tries |
maximum number of failed attempts before giving up |
n |
number of random steps to take to find best direction |
This is a novel method for finding more interesting projections for
the guided tour. It works by first taking a small step in n
random directions, and then picking the direction that looks most
promising (based on the height of the index function). Once the best
direction is found, it performs a linear search along the geodesic in
that direction, traveling up to half way around the sphere.
You should not to have call this function directly, but should supply
it to the guided_tour
as a search strategy.
