Each shader now has sample image, example mesh configuration and example
rendering setup. Also properly documented all attribute types and made
introductory chapter for whole Shaders namespace.
Why did I do this:
* It is more clean, shorter and nice looking with method chaining,
i.e. instead of:
shader.setColor(...)
.setOtherParam(5);
texture1.bind(MyShader::Texture1Layer);
texture2.bind(MyShader::Texture2Layer);
We now have this:
shader.setColor(...)
.setOtherParam(5)
.setTexture1(texture1)
.setTexture2(texture2);
* It is now also clear which texture type is expected, the layer
constant did not say anything about type.
* Also it is possible to use new features (multi bind, bindless
textures etc.) while preserving the same public API.
The only potential disadvantage is that the textures don't stay bound
like uniform values do, but this become a non-issue with bindless
textures. As usual, the old way is now deprecated and will be removed in
some future release.
As we are now using absolute includes, there is no need to prefix
everything with "magnum<Namespace>" etc. All generated configuration
files are renamed to configure.h and their path is included _before_
everything else to avoid accidental collisions.
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.
Defines common attributes which are shared by majority of the shaders,
allowing mesh to be configured for the generic shader to be used with any
of them.
Makes some cases less consistent (and some convenience shortcuts
impossible), but goes well with the attitude "don't use pointer when it
can't be null".
Inspired in STL, base templated class is renamed to BasicColor{3,4} and
typedef'd with Float type to Color{3, 4}. It is much nicer to write
this:
Color3(1.0f)
Color3::fromHSV(25.0_degf, 0.5f, 0.9f);
instead of this:
Color3<>(1.0f);
Color3<>::fromHSV(25.0_degf, 0.5f, 0.9f);
1.0 is taken as shape center (white), 0.0 as shape surroundings (black).
It was unintuitive to have it reverted, updated documentation to make it
right.
