Much like Shape::collides() is equivalent to the more low-level
collision detection using operator%, the Shape::collision() returns
collision details similarly to operator/. Currently only Sphere/Sphere
and Sphere/Point collision is done, thus the dispatch is nearly empty.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Seems like an essential part of the toolbox -- we have Point, LineSegment
and Line and now we have also all "swept sphere" alternatives to them --
Sphere (swept "along" the point), Capsule (swept along line segment) and
Cylinder (swept along infinite line).
"Implemented" collision detection with point and sphere, which is just
simplified version of collision detection implemented for Capsule (i.e.
no need to check for cap cases).
This class now stores the tree in flat array, making it easier for user
to query the contents, but the internals are much more complicated. This
solution already reduces allocation count by count of nodes in the tree,
future work might remove the per-shape allocation altogether by using
large typeless array and placement-new etc.
