Text example doesn't render any text on iOS Safari
Only the background color is rendered. The app doesn't seem to crash.
The device I'm using (iPhone 5) seems to be SDF-capable since it's able to run this demo: https://evanw.github.io/font-texture-generator/example-webgl/
I haven't been able to make my game render any SDF text or image on iOS either. The game runs, but just won't render SDF. I've tried to fiddle with mipmaps (following the answer of this Stack Overflow question: https://stackoverflow.com/questions/27892283/libgdx-distance-field-font-support-on-ios/49968657 ), without success.
example cubemap does work on Intel HD Graphics 530
cannot load the cubemap texture, got black screen, while executed successfully on nvidia cards.

ImGui Rendering State Features
In the imgui example, there's a set of comments here that say it's sufficient to do this in the renderer constructor if you're only drawing imgui elements.
/* Set appropriate states. If you only draw imgui UI, it is sufficient to
do this once in the constructor. */
GL::Renderer::enable(GL::Renderer::Feature::Blending);
GL::Renderer::disable(GL::Renderer::Feature::FaceCulling);
GL::Renderer::disable(GL::Renderer::Feature::DepthTest);
GL::Renderer::enable(GL::Renderer::Feature::ScissorTest);Which suggests you can just comment out these lines:
// /* Reset state. Only needed if you want to draw something else with
// different state next frame. */
// GL::Renderer::disable(GL::Renderer::Feature::ScissorTest);
// GL::Renderer::enable(GL::Renderer::Feature::DepthTest);
// GL::Renderer::enable(GL::Renderer::Feature::FaceCulling);
// GL::Renderer::disable(GL::Renderer::Feature::Blending);While this comment seems valid on Emscripten, at least when I build locally with SDL2 this doesn't work. By doing nothing other than commenting out the line disabling the scissor test, I get those solitaire card effects or glitchy Windows95 things being dragged and I get a trail of the old imgui windows.
Frankly, I'm somewhat baffled.
That being said, I probably have an odd setup. I'll just list what I think would be relevant.

Rendering issues with firefox
I am not sure if this is an issue with magnum itself or with firefox (perhaps webgl2 only?), but the model viewer seems to have some depth issues. It does not happen with Edge on the same computer.

Text example setup
I have tried to follow closely the documentation to run the
I am on windows, using vcpkg (it's quite neat!).
I have vcpkg-installed: sdl2, magnum, corrade, magnum-plugins[freetypefont]
I am trying to stay entirely within visual studio (2017 community edition) so I have edited CMakeSettings.json to include the CMake directives:
WITH_TEXT_EXAMPLE=ON
CMAKE_TOOLCHAIN_FILE=<points to vcpkg.cmake>
CMAKE_RUNTIME_OUTPUT_DIRECTORY="bin"
I have one blocking issue and two minor ones:
A) at runtime I get the error:
PluginManager::Manager::load(): plugin FreeTypeFont is not static and was not found in
What step am I missing?
B)when I run the install target, only magnum-text.exe and magnum-triangle.exe get copied in the install location (magnum-examples\install\x86-Debug\bin), none of the supporting libs are present so I am running from the build directory for the time being, i.e. magnum-examples\build\x86-Debug\src\text\bin
C)SDL2.dll doesn't get copied to the build directory along with the other libs, I have to do it manually. I thought the point of CMAKE_RUNTIME_OUTPUT_DIRECTORY was to grab all the dependencies?
_degf Error
Compiler can't read _degf format.
Examples is "PrimitivesExample"
Missing line from primitives tutorial doc
The doc stops early:
@until std::tie
Thus it misses out on this line:
indexBuffer.setData(indexData, BufferUsage::StaticDraw);
Without that line, the program crashes. I had quite a headache trying to compare my code to the tutorial code to see where I had gone wrong.
EDIT: Looks like you addressed it in 4ba9644 - thanks! I'll let you close this issue.

Examples don't pass cmake for Emscripten
On Debian 8 x86_64 I've successfully built and installed corrade, magnum and magnum-plugins¹ for both the system's ELF clang-3.5 chain and for the emscripten (emcc 1.36.0) chain.
I sudo-installed corrade, magnum and magnum-plugins¹ underneath default /usr/local; "emsdk_portable" resides in my home directory.
Given that environment, the magnum viewer example builds flawlessly with the clang for ELF. and emcc and em++ compile HelloWorld programs to valid js.
On the example tree, however, after git'ing the toolchains module and patching toolchains/generic/Emscripten.cmake to point to my emsdk location, cmake (3.0.2), invoked from a build dir underneath the magnum-examples - root dir like
cmake -DCMAKE_TOOLCHAIN_FILE="../toolchains/generic/Emscripten.cmake" ..
first detects valid emcc and em++ but then fails with
CMake Error at /usr/share/cmake-3.0/Modules/FindPackageHandleStandardArgs.cmake:136 (message):
Could NOT find Corrade (missing: _CORRADE_MODULE_DIR)
Call Stack (most recent call first):
/usr/share/cmake-3.0/Modules/FindPackageHandleStandardArgs.cmake:343 (_FPHSA_FAILURE_MESSAGE)
modules/FindCorrade.cmake:457 (find_package_handle_standard_args)
modules/FindMagnum.cmake:186 (find_package)
CMakeLists.txt:43 (find_package)
For my purposes, not all of the examples would need to be compiled to js, if it'd be just the viewer example itself - like it apparently was for mosra's showcases - I'd be happy enough.
Due to the complexity of the build infrastructure involved I cannot be totally sure that this is an issue - it is a perfectly plausible alternative hypothesis that I just messed sth up.
But I've tried several approaches to alter cmake-module paths, setting missing variables on the command line or in the cmake-gui etc, but to no avail yet.
Could you look into that, please?
Yours sincerely,
decltype-auto
P.S. @mosra: Your Magnum is a BRILLIANT piece of software!
Likely the cleanest real-life C++11/14 I've yet seen; I'm really enthusiastic about it.
¹ For emscripten just with
-DWITH_ANYAUDIOIMPORTER=ON
-DWITH_ANYIMAGECONVERTER=ON
-DWITH_ANYIMAGEIMPORTER=ON
-DWITH_ANYSCENEIMPORTER=ON
-DWITH_OPENGEXIMPORTER=ON
due to lack of libpng, libfont_whatever_ in my emsdk environment.
How to adapt native OpenGL code with native Camera capture to Magnum, ImGui, MagnumGL.
Greeting @mosra I found an amazing code which wraps Camera capture and there is an example with OpenGL displaying the raw data coming from the camera.
Since I don't know yet how to integrate OpenGL, Magnum, and display all of above inside of ImGui I'm wondering if you can give me some guidance.
This is the original code : https://www.codeproject.com/Articles/776058/Capturing-Live-video-from-Web-camera-on-Windows-an`
The part which interests me is Update on VS2013Express for Desktop
How do I need to think to be able to adapt that code for ImGui, Magnum, OpeGL Wrapper and camera capture?
Thank you for your suggestion.

Trouble loading plugins in Viewer demo
The maintainers of this project are doing a formidable job. 😄
I am trying to get the viewer example going (2020.06).
I installed magnum the vcpkg way, I use CMake on Ubuntu 20.04.
Then, I installed the magnum plugins too vcpkg install magnum-plugins\[\*\].
Now, I see that these plugin libraries are present in the lib dir of vcpkg, although static .a.
When I try to run the example, I run into the following issue:
PluginManager::Manager::Manager(): none of the plugin search paths in {/home/me/vcpkg/installed/x64-linux/debug/bin/magnum-d/importers, ../lib/magnum-d/importers, magnum-d/importers} exists and pluginDirectory was not set, skipping plugin discovery
PluginManager::Manager::load(): plugin AnySceneImporter is not static and was not found in
I have tried passing the vcpkg prefix to the plugin manager.
I feel like I am missing a step, how do I get dynamic plugins working the vcpkg way?
Thanks in advance for your time.
Cannot compile examples with apt package
Following the guide I tried to compile TriangleExample.cpp. But I get these errors:
magnum-examples/src/triangle/TriangleExample.cpp:65:24: error: no matching function for call to ‘Magnum::GL::Buffer::setData(const Magnum::Examples::TriangleExample::TriangleExample(const Magnum::Platform::Sdl2Application::Arguments&)::TriangleVertex [3])’

Shaders::VertexColor2D::Color3{});
Maybe it is a version mismatch problem, but I dont see in the docs any mention to these changes.
BTW magnum-examples-dev package is not present in the Ubuntu package (I am trying to run it in Ubuntu 18.04)
Viewer example closes at startup...
Hi,
I can't get the viewer example to start on Windows, VS2019
When executing the .parse(argc, argv) the application exists with exit(1) without printing anything.
The exact part of the code where this is happening is here (checked with the debugger)
Utility::Arguments args;
args.addArgument("file").setHelp("file", "file to load")
.addOption("importer", "AnySceneImporter").setHelp("importer", "importer plugin to use")
.addSkippedPrefix("magnum", "engine-specific options")
.setGlobalHelp("Displays a 3D scene file provided on command line.")
.parse(arguments.argc, arguments.argv);
An I missing some arguments when executing the application, if yes how to pass them?
Thansk!

Fix HDPI problem for WebGL examples
Hi there,
I create this issue to make sure we don't forget about our high-DPI problem: mouse position is not correct when running WebGL examples on high DPI monitor.
The examples still have this problem: Bullet and Fluid2D (please add more if you know).
Cubemap example not running
I trying next:
- Install Ubuntu Mate (16.04) in PC
- Install all corrade, magnum, etc..
- Install examples (with cubemaps custom flag)
- Install plugins (I installed only jpeg and png at this moment)
Triangle example working. But I can't run cubemap example.

<box2d/box2d.h> case-sensitive issue
Currently Box2DExample.cpp uses #include <Box2D/Box2D.h> while the actual box2d repo uses lower-case. This cause issue with case-sensitive filesystem on Linux. Change the include to use #include <box2d/box2d.h> fixes it.
Clearly document the implications of deferred GL context creation
I'm trying to get the viewer example to work with the example window setup code (mainly to enable MSAA for modeling viewing).
By default, viewer sets up the window like this:
ViewerExample::ViewerExample(const Arguments& arguments):
Platform::Application{arguments, Configuration{}
.setTitle("Magnum Viewer Example")
.setWindowFlags(Configuration::WindowFlag::Resizable)}
{ ... }But when the window was setup like this (took from other examples):
ViewerExample::ViewerExample(const Arguments& arguments)
: Platform::Application{arguments, NoCreate} {
/* Setup window */
{
const Vector2 dpiScaling = this->dpiScaling({});
Configuration conf;
conf.setTitle("Magnum Model Viewer Example")
.setSize(conf.size(), dpiScaling)
.setWindowFlags(Configuration::WindowFlag::Resizable);
GLConfiguration glConf;
glConf.setSampleCount(dpiScaling.max() < 2.0f ? 8 : 2);
if (!tryCreate(conf, glConf)) {
create(conf, glConf.setSampleCount(0));
}
}
...
}the code compiled but when executed I got Segmentation fault. I'm not quite sure if this is the only way to enable MSAA or if this is directly related to the viewer example but so far this is the only example that has this issue.
Magnum (2020.06) and all other dependencies were compiled as CMake subprojects. I'm working on Ubuntu 20.04 x86_64.
Thank you in advance for your investigation.
SDL2 OpenGL ES examples do not work on Linux x86-64
My prefix folder is /opt and I build everything with BUILD_STATIC=OFF, but I still receive the error
Utility::Resource: group 'MagnumShaders' was not found
Whenever I try to run the Triangle example.
Also, the OpenGEX importer does not work with GCC 4.8.2 and the compiler throws errors.
WebXR Fails to Load
Hi,
I just did a build of Platform::EmscriptenApplication and it works just fine with the default "myApplication" project and the triangle example, displaying them correctly in the browser. However, I run into an issue when I attempt to build the WebXR example.
The project compiles just fine without any errors, and when I run it on a local server, it displays the expected page in the browser, even showing the correct scene in the small window. But when I try to enter the scene in VR, I just get an infinite loading screen, and the console outputs this error:
Uncaught (in promise) ReferenceError: dynCall is not defined
at onSessionStart (magnum-webxr.js:6534)

$func308 @ magnum-webxr.wasm:0x9c50
mouseEventHandlerFunc @ magnum-webxr.js:4677
jsEventHandler @ magnum-webxr.js:4499
I also get a similar error when I exit the session. I'm attempting to view this using port forwarding on a Quest 2, and the CMake commands I'm using are:
mkdir build-emscripten && cd build-emscripten
cmake ..
-DCMAKE_TOOLCHAIN_FILE="../toolchains/generic/Emscripten-wasm.cmake"
-DCMAKE_PREFIX_PATH="/home/tseppala/.emsdk/upstream/emscripten/system"
-DCMAKE_INSTALL_PREFIX=/mnt/h/CodeTests/MagServer
cmake --build .
cmake --build . --target install
Did I forget to include something in my build? Is this a problem with my Emscripten installation? Or am I just typing the wrong commands?
Any help would be greatly appreciated.
Object Picking not working under Mesa
As mentioned in mosra/magnum#80, the object picking example is apparently working only on NVidia binary drivers -- on Mesa clicking objects does nothing but the scene is rendered correctly.
The error might be related to the behavior noted in #12 (after getting it to somewhat working state I couldn't pick any object).
Audio Example not working
https://magnum.graphics/showcase/audio/ doesn't play any audio on my end.
Tested on recent Chromium and Firefox (webgl1 enabled).
Also according to someone else:
I get this in Vivaldi's console:
The AudioContext was not allowed to start. It must be resumed (or created) after a user gesture on the page.
https://developer.chrome.com/blog/autoplay/
So, yeah, looks like some media policy thing.
How to build Imgui example?
I have no problems with compiling MagnumIntegration::ImGui but Imgui example can't builded.
All packages installed via vcpkg.

Porting Object Picking to ES3 / WebGL 2
Should be okay from Magnum side, the problem is that no browser is currently able to handle required WebGL 2 functionality:
Firefox
- Renderbuffers don't accept
RenderbufferFormat::RGBA8/RenderbufferFormat::R8UI(but textures do) -- possibly related: Bug 1048733 - WebGL2 - Implement Renderbuffer Objects - When replacing renderbuffers with textures, it's no possible to use
TextureFormat::R8UIfor framebuffer attachment (says that the attachment is incomplete) - It's not possible to call
Framebuffer::mapForRead()withFramebuffer::ColorAttachment{1}(butmapForDraw()behaves okay) - Sometimes the example doesn't even render first frame (might be Emscripten/optimization issue)
- If
Framebuffer::blit()is called without clearing the destination framebuffer before, the buffer is not updated at all (I might be doing this wrong, but works on desktop)
More possibly related bugs:
- Bug 1048732 - WebGL2 - Implement Framebuffer Objects
- Bug 1170842 - WebGL 2 - Finish implementing framebuffers
- Bug 1170849 - WebGL 2 - Rendering to MRT failures
Blink-based browsers
From what I tested last time (things could be different now, though):
- Chromium still reports
"WebGL 1.0"renderer string for WebGL 2 contexts - Chromium does not support GLSL ES 3.0 (possibly related: https://code.google.com/p/chromium/issues/detail?id=485334)
ES3
- I should try compiling and running the example on some strict ES3 implementation (either desktop one or mobile)
typo, should be jpge-importer
MeshData.h include no longer valid?
I am following this example:
https://doc.magnum.graphics/magnum/examples-primitives.html
I did set myself up with vcpkg...
MeshData.h doesn't seem to be valid and there are ...2D and ...3D suffixes to that header now.
Is this a known issue?

Creating my own glb
Hello,
I'm trying to change the model from the viewer example but I couldn't find a way to create my own glb file with blender... The glb file I exported from blender is not working, the error is:
Opening file ../../magnum-examples/src/viewer/out.glb Trade::AbstractImporter::openFile(): cannot open file ../../magnum-examples/src/viewer/out.glb
I tried re building the example with the following line modified in the CMakeLists.txt:
install(FILES out.glb DESTINATION ${MAGNUM_DATA_INSTALL_DIR}/examples/viewer)
In the magnum installation's plugins I checked:
-DWITH_ASSIMPIMPORTER=ON \ -DWITH_DDSIMPORTER=ON \ -DWITH_STBIMAGEIMPORTER=ON \ -DWITH_STBTRUETYPEFONT=ON \ -DWITH_TINYGLTFIMPORTER=ON
Am I doing something wrong ?
Dragging and Dropping Example?
Hello,
Sorry if this not the correct place to ask this as I could not find a Magnum Slack channel or Discord server so I am not sure where the Magnum user community is located.
I am wondering if there are any examples of using the mouse in a wasm seen to grab an object and move just the object around to different positions and releasing the object?
The closest thing that I found was an Object Picking demo:
https://doc.magnum.graphics/magnum/examples-picking.html
but it seemed only to allow you to select an object but not move that single object to a new position within the scene.

ViewerExample: Generate mesh normals logic is backwards
The code:
if(meshData->hasAttribute(Trade::MeshAttribute::Normal))
flags |= MeshTools::CompileFlag::GenerateFlatNormals;
seems backwards, as we'd only want to generate normals if none were present in the mesh data.
This would need to be fixed in the example webpage as well.

Undefined variabls
Hello guys,
after the last update to magnum "master" I got compilation errors If I build examples.
Did something change for magnum linking? This came after last pull. There is a ton of undefined types. Or I did something wrong?
example of the error:
e:\git\magnum-examples\src\shadows\shadowsexample.cpp(290): error C2027: use of undefined type 'Magnum::Math::Color3<Magnum::Float>'
My build script (tested Windows build):
https://github.com/janbajana/script-helpers/blob/master/cmake-scripts/setup-magnum-examples-build.sh
Area light example, area quads don't use depth buffer
Love the demo btw :)
Just spotted lights don't occlude each other correctly (yellow is the closest in this screenshot)
Unable to build ImGui example using Vcpkg out of the box
Hi,
I don't know if I've done something wrong, most likely have, but I'm trying to build this repo after using VCPKG.
-
I used VCPKG to install the magnum packages and used this command and installed the following libraries and cloned this repo:
./vcpkg install --head corrade magnum magnum-integration imgui
-
I set CMAKE_TOOLCHAIN_FILE to my VCPKG cmake file in build systems (vcpkg/scripts/buildsystems/vcpkg.cmake) and built the project with only the
WITH_IMGUI_EXAMPLEset to ON.
However, after attempting a build, my CMake returns this:

Could someone help me understand what I've done wrong. As you can tell I'm using Clang as my compiler and I'm currently running macOS.
Thanks,
George
vcpkg build: SDL2.dll dependency is not automatically copied
From #41 (comment).
When building with vcpkg (e.g. x64-windows triplet), you can usually just run the application and it "just works", because all the dependency DLLs are automatically copied to the target output folder.
This works well for all dynamic libraries (e.g. MagnumPlugins::FreetypeFont), but not for Sdl2Application, which is always linked statically.
Since the executable is a dynamic library itself, I would expect it to work anyway, but that is maybe not how vcpkg works.
@mosra You may assign me, I will have a look at this in near future.
EmscriptenApplication.js:35:2:WebXR unsupported in this browser
Hi,
I build webxr for emscripten in ubuntu, and generated :
EmscriptenApplication.js
magnum-webxr.html
magnum-webxr.js
magnum-webxr.wasm
WebApplication.css
I setup a server using python SimpleHTTPServer and access the html with my PC browser,
I could see a image in the browser but there's error log in console:WebXR unsupported in this browser
I tried it in chromium and Edge, they have the same issue.
my Chromium version is 83.0.4103.116（正式版本） （32 位）
Have anybody met this kind of issue? any help will be appreciated!
Object Picking not working on Firefox
At least on FF 62.0.3 (Objects do not change color when clicked.)
Updated to 63.0 (64-bit); same behavior.
Works fine on Chrome
Any gizmos Demo?

Looks similar to magnum-bootstrap issue 3
EDIT: the issue was that libmagnum was compiled with clang with the sample was compiled with gcc. Using the same compiler for both solved the issue.
