Compared to Corrade, the improvement in compile time is about a minute
cumulative across all cores, or about 8 seconds on an 8-core system (~2
minutes before, ~1:52 after). Not bad at all. And this is with a
deprecated build, the non-deprecated build is 1:48 -> 1:41.
Not that C++ STL and exceptions would be anything to take inspiration
from, but there's std::out_of_range. Python IndexError is also specified
as "index out of range", not "bounds".
Instead of saying "which is not supported" in each assert, which is
vague and might imply that "it eventually will be supported", document
the actual reason in a single place, which is the MeshAttributeData docs.
Otherwise it may be hard to guess which of them is failing. *Ideally*
the assert would also contain the stride vs type size, maybe I do
that next time I spend that much time investigating why it asserts.
The array size is always last, defaulting to 0. This makes it consistent
with the offset-only constructor and removes two unnecessary overloads.
It's a breaking change, but I don't think array attributes have many
users yet -- and better to do this now than later. In any case, sorry
about breaking your code.
Until now, except for an attribute-less index-less mesh, the vertex
count was only implicitly taken from passed attributes, but it was
severely limiting:
- There was no way to set vertex count for an attribute-less
indexed mesh, which didn't make sense
- All code that made non-owning MeshData instances referencing another
MeshData had to explicitly handle the attribute-less corner case to
avoid vertex count getting lost
- Offset-only attributes couldn't be used to specify static layout of
meshes with dynamic vertex count, causing unnecessary extra
allocations especially in the Primitives library.
The combineIndexArrays() and combineIndexedArrays() API is replaced with
a more generic combineIndexedAttributes(), and thanks to that we also
don't need STL-based duplicate() and removeDuplicates().
Originally this was done in order to make handling of deserialized data
much simpler (as for those attributes also need to only contain an
offset into some unknown data array), but seems this could be very
useful elsewhere as well -- for example when the layout is known
beforehand but the actual data not yet -- such as in the Line and
Gradient primitives (going to switch them to this in the next commit).
What still unfortunately has to be known in advance is the actual vertex
count (as supplying it directly to MeshData would mean adding 6 new
constructor overloads, and there's enough of those already). Might
revisit later.
Provide a version taking StridedArrayView instead, taking an arbitrary
view and also arbitrary index type. Also introduce duplicateInto() which
doesn't even allocate, but rather writes the output to pre-existing
location.
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.
* In shader uniforms (projectionMatrix makes more sense than projection
alone)
* For underlying types for SceneGraph transformation. It is already
used in Drawable::clean() as transformationMatrix, so why not use it
also in AbstractFeature::clean(). Moreover, clean() could be in
future also done using something else, this helps to distinguish the
type just from parameter name.
* In Physics shapes - applyTransformationMatrix() (as it could be in
future also done using something else).
Magnum.h now doesn't include anything except OpenGL headers, thus
changes in Math library don't trigger recompilation of everything, but
only of things really depending on it.
Math constants moved to separate file for similar reasons, de-inlined
some functions to remove the need for some #includes.
Now we can use CORRADE_COMPARE() almost exclusively for comparing
Vector, Matrix instances and all containers from STL. Tests running time
for all 31 tests is now around 0.1 sec instead of two seconds like
before.
Disabled compilation of all benchmarks, because TestSuite cannot handle
them yet.
PKGBUILD from AUR now can shamelessly use check() function without
unnecessary dependencies.
