Changelog » Examples

Dependency changes

• Minimal supported CMake version is now 3.5, changed from 3.4, since CMake 3.27+ warns if a compatibility with CMake below 3.5 is requested. Older versions are not supported anymore and all workarounds for them were removed. This is a conservative change, as there are no known supported distributions which would have anything older than 3.5.

New features

• The Triangle using Vulkan is now written fully using the new Vk and ShaderTools libraries, with no raw Vulkan code left
• New Textured triangle using Vulkan, mirroring the OpenGL Textured Quad with Vulkan APIs

Changes and improvements

• The original Textured Triangle example was changed to Textured Quad to show also a low-level indexed mesh setup
• The Primitives example got significantly simplified by using MeshTools::compile() instead of inflexible, verbose and slow lower-level APIs. Description of those got moved to the Trade::MeshData class documentation.
• Fixed the WebXR example to look correctly on HiDPI
• The WebVR example was obsoleted by the WebXR example and is now removed
• The Cube Map example can now load combined cube map files such as EXR

Build system

• Updated the Box2D example to work with latest Box2D 2.4 (see mosra/magnum-examples#90 and mosra/magnum-examples#92)
• Linux, Emscripten and macOS builds were migrated from Travis to Circle CI
• The Homebrew package now uses std_cmake_args instead of hardcoded build type and install prefix, which resolves certain build issues (see mosra/homebrew-magnum#6)
• Updated Debian build instructions to pass --no-sign to dpkg-buildpackage, avoiding a confusing error message that might lead people to think the packaging failed (see mosra/magnum-plugins#105)
• It's now possible to use <PackageName>_ROOT to point to install locations of dependencies such as Corrade on CMake 3.12+, in addition to putting them all together inside CMAKE_PREFIX_PATH. See also mosra/magnum#614.
• Examples are now put into a MagnumExamples folder on MSVC and Xcode (see mosra/magnum-examples#107)
• Created a RPM package with a helper script for building (see mosra/magnum-examples#110)

Bug fixes

• The ports branch of the Object Picking was fixed to work properly on Firefox ... after three long years. See mosra/magnum-examples#53.
• The Octree example got fixed to properly remove all invalid points (see mosra/magnum-examples#99)
• The Model Viewer used a wrong logic for generating mesh normals (see mosra/magnum-examples#109)

Deprecated APIs

• All CMake build options are now prefixed with MAGNUM_. For backwards compatibility, unless MAGNUM_BUILD_DEPRECATED is disabled and unless a prefixed option is already set during the initial run, the unprefixed options are still recognized with a warning. See also mosra/corrade#139.
• The WITH_TEXTUREDTRIANGLE_EXAMPLE CMake option is still recognized on builds with MAGNUM_BUILD_DEPRECATED enabled, but will produce a warning. Use MAGNUM_WITH_TEXTUREDQUAD_EXAMPLE instead.

Documentation

• Updated license link for Source Sans Pro used by the 2D Fluid Simulation, 3D Fluid Simulation, ImGui and Text rendering examples (see mosra/magnum-examples#95)

New features

• New 2D Fluid Simulation example (see mosra/magnum-examples#71)
• New 3D Fluid Simulation example (see mosra/magnum-examples#69, mosra/magnum-examples#70, mosra/magnum-examples#84,)
• New WebXR example (see mosra/magnum-examples#73)
• New ArcBall Camera example (see mosra/magnum-examples#75, mosra/magnum-examples#85)
• New Ray Tracing example (see mosra/magnum-examples#76)
• New Animated GIF example (see mosra/magnum-examples#80)
• New Octree example (see mosra/magnum-examples#86)

Changes and improvements

• The ImGui example now lets ImGui update the application cursor (see mosra/magnum-integration#56)
• Avoid using obsolete APIs in the ImGui example (see mosra/magnum-integration#65)
• Fixed the Object Picking to not limit object count to 256 (see mosra/magnum-examples#79)
• Ported the Object Picking to use the new builtin Object ID support in Shaders::Phong instead of a custom shader (see mosra/magnum-examples#81)
• The Box2D and Bullet Physics examples are now using instanced rendering to draw the whole scene in a single draw call.

Build system

• The library again compiles and tests cleanly with CORRADE_NO_ASSERT enabled, and this setup is verified on the CI to avoid further regressions

Bug fixes

• The Object Picking and Bullet Physics examples weren't properly handling mouse events on HiDPI systems that have different window and framebuffer size (see mosra/magnum-examples#72 and mosra/magnum-examples#74)

Dependency changes

• Minimal supported CMake version is now 3.4. Older versions are not supported anymore and all workarounds for them were removed. Download a prebuilt release of a newer version if you need to use Corrade on older systems (such as Ubuntu 14.04 or Debian 8). This is a conservative change that shouldn't affect any additional distribution compared to the CMake 3.1 requirement in 2019.01.

New features

• New DART Physics example showing integration with DART using DartIntegration (see mosra/magnum-examples#63)

Changes and improvements

• Switched all examples to use the new Platform::EmscriptenApplication on Emscripten (see mosra/magnum-examples#60 and mosra/magnum-examples#59)
• Switched the Motion blur and Object Picking examples to use MeshTools::compile() for a clearer and easier-to-understand code (see also mosra/magnum-examples#62)
• The Cube Map now tries to find the bundles images first instead of requiring the user to always pass a path (see also mosra/magnum-examples#44)
• Documented how to enable and use importer plugins in Textured Quad and Model Viewer (see mosra/magnum#375)

Bug fixes

• The Area Lights example wasn't using the depth buffer (see mosra/magnum-examples#57)
• Adaptations to header cleanup in Magnum for faster compile times, various other cleanup (see mosra/magnum-examples#54, mosra/magnum-examples#66)

Dependency changes

• Minimal supported GCC version is now 4.8.1, GCC 4.7 is not supported anymore. Minimal Clang version is now 3.3, since that's the first version with a complete C++11 support. See also mosra/magnum#274.
• Minimal supported CMake version is now 3.1. Older versions are not supported anymore and all workarounds for them were removed. Download a prebuilt release of a newer version if you need to use Corrade on older systems (such as Ubuntu 14.04 or Debian 8). See also mosra/magnum#274.

New features

• New ImGui example showing integration with ImGui using ImGuiIntegration (see mosra/magnum-examples#51)

Changes and improvements

• Plugged memory leaks in the Bullet Physics example, automatically removing fallen objects thats are too no longer visible (see mosra/magnum-examples#52)

Documentation

• Mention the required extra CMake boilerplate in the first two examples (see mosra/magnum#309)

New features

• New Box2D example showing usage with Box2D
• New Mouse Interaction example showing advanced mouse interaction (see mosra/magnum-examples#46)
• New Triangle using Vulkan example showcasing basic Vulkan usage with Magnum

Changes and improvements

• Simplified the Bullet Physics and Audio, removing use of the deprecated Shapes library.
• The Model Viewer tutorial is greatly simplified to make use only of the most essential APIs needed to make it working
• The Oculus VR and Leap Motion examples were updated to not depend on deprecated functionality (see mosra/magnum-examples#49)
• The Model Viewer example is now ported to Android (see mosra/magnum-examples#50)

Build system

• There's now a PPA for Ubuntu packages. See Packages for Debian, Ubuntu and derivatives for more information. See also mosra/magnum-examples#43.

Documentation

• Extended the Primitives example with info about handling of generic mesh data (see mosra/magnum-examples#48)
