Shaders: basic text shader.

Shaders: suffix all existing shaders with GL. To make room for Vulkan shaders. Also renaming the headers, of course everything is still aliased to the old names (and marked as deprecated).

Shaders: basic text shader.
14 years ago
Shaders: implement texture coordinate transformation for all shaders. Except MeshVisualizer and VertexColor, which don't have any texturing, so there it's not needed. In most cases the tests are reusing existing ground truth files and only modifying transformations / flipping images.

#include <Corrade/Containers/EnumSet.hpp>
GL: better handle a case of async link failures. The new async APIs were just checking the link status, and printing the linker error. Because drivers commonly do all that in a single step, without really separating compilation from linking (or at least that's what I thought?), I assumed the linker error would contain *also* the compilation error, if any. But on a quick check with Mesa that's not the case, I only get "error: linking with uncompiled/unspecialized shader", which is very useless. Which means, to get proper error output, the checkLink() function now explicitly takes a list of the input shaders. It will unconditionally go through them at the beginning and call checkCompile() on each. To further encourage the shaders to be passed, there's no default argument -- so if the application calls checkCompile() on its own for some reason, it has to pass an empty list to checkLink().

Shaders: add UBO support to all shaders.
5 years ago
#ifndef MAGNUM_TARGET_GLES2
GL: port Shader and ShaderProgram away from std::string. Same as in the previous commit, most cases are inputs so a StringStl.h compatibility include will do, the only breaking change is GL::Shader::sources() which now returns a StringIterable instead of a std::vector<std::string> (ew). Awesome about this whole thing is that The Shader API now allows creating a shader from sources coming either from string view literals or Utility::Resource completely without having to allocate any strings internally, because all those can be just non-owning references wrapped with String::nullTerminatedGlobalView(). The only parts which aren't references are the #line markers, but (especially on 64bit) those can easily fit into the 22-byte (or 10-byte on 32bit) SSO storage. Also, various Shader constructors and assignment operators had to be deinlined in order to avoid having to include the String header, which would be needed for Array destruction during a move.

Shaders: drop the createCompatibilityShader() helper. With the workarounds moved to the GL::Shader class itself, it's just a complicated wrapper for adding the compatibility.glsl file and a rather strange way to define a file-local helper for resource import on static builds. Do that directly instead.

Shaders: take constructor arguments via a Configuration instance. Because it was no longer bearable with three UnsignedInt arguments in a row, especially when some of them are only available on a subset of platforms. And it would get even worse with introduction of planned features such as multiview or skinning. Backwards compatibility is in place, as always.

Shaders: avoid including GL/Shader.h in headers. The class is rather heavy (strings, STL vector) and it'll stay heavier than strictly needed even after the planned STL cleanup -- shader users should not bear the overhead of Array, StringView etc. that it needs in order to compile the shader sources. I might eventually come to a different conclusion (maybe separating GL::Shader population and usage like doing in Vulkan with CreateInfos), but right now this commit has the best available solution -- converting the instance to a lightweight class containing just ID and type, and then converting that back to a GL::Shader upon checking compilation/link status. While at it, also removed the not-strictly-needed Optional usage from the header. It wouldn't work with forward-declared GL::Shader anyway.
