That gives the change of storing that data in flash storage in some
architectures. That doesn't happen yet though, some extra changes are required
for that to happen.
We don't actually need all of them, since the second half is for the opposite
triangles. In that case we just need to negate the resulting vector when
changing basis.
That function was only being used by the unit tests and the benchmark. In order
to remove memory usage, the triangles will be removed, since we don't actually
need to keep them in real situations. Thus, this patch removes that function
and copy those triangles to the test and benchmark.
This is the second optimization. With that we don't have to iterate over the
umbrella's components.
The table below summarizes the mean CPU time in ns from the brenchmark results
on an Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz processor:
| Naive implementation | First Optimization | Second Optimization
------------------------------------------------------------------------
Min. | 26.0 | 28.00 | 26.0
1st Qu.| 78.0 | 48.75 | 39.0
Median | 132.0 | 57.00 | 41.0
Mean | 130.1 | 61.20 | 41.6
3rd Qu.| 182.2 | 76.00 | 47.0
Max. | 234.0 | 98.00 | 54.0
If v is the null vector, then alpha * v is still the null vector for any alpha
as a real number. That means that the null vector doesn't cross any section.
This is a first optimization of the algorithm. The struct for the neighbor
umbrella has only one member, but new members will be added in the next
optimization.

This optimization reduces the mean time for the worst case (Max. line) by more
than 50%.
- Change the order of the icosahedron triangles so that there's a uniform way of
finding the opposite triangle. The order visually still makes sense.
- Change test to accommodate the order change.
Google Test allows to instantiate tests for a list of different values, which
are called parameters. A common use of that feature in Ardupilot will be that a
parameter will be represented by an object that will have the value to be
tested and information about that value. That information will basically map
the expected behavior of tests on the value stored by the parameter.
The macro added in this patch allows to easily print the value of a failed
test's parameter.
GCC 6 has a new warning about misleading indentation:
../../APMrover2/system.cpp: In member function ‘void Rover::set_mode(mode)’:
../../APMrover2/system.cpp:272:5: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
if (control_mode == AUTO)
^~
../../APMrover2/system.cpp:275:2: note: ...this statement, but the^Bn latter is misleadingly indented as if it is guarded by the ‘if’
control_mode = mode;
^~~~~~~~~~~~
The issue here is that we are mixing tabs and spaces. Remove tabs and re-indent
the code.
Passing an unsigned value to abs() causes compilation error in gcc 6.1.1
(and doing that doesn't make sense too).
As a bonus, this patch fixes the code, since, for two unsigned integers
a and b, such that a > b, (a - b) without the casting to a signed
integer would produce garbage in the context of this patch. The type
int32_t is enough for the cases covered by this patch.
