Rive Runtime runtime-v0.1.36
fix(vulkan): Resolve driver crash on some mobile GPUs (#12403) 1deebb93aa The tiled gms exposed a driver crash on some specific older mobile devices, which was due to the (valid) way we were binding samplers. In order to work around this issue, in Vulkan the tesselate, atlas, grad, and image textures are now bound as COMBINED_IMAGE_SAMPLER so that the "immutable sampler" descriptor set goes away, as well as IMAGE_SAMPLER_IDX since now on (almost) all backends they're the same index (like with the other textures). WebGPU, unfortunately, does not support combining samplers and textures into the same binding within a binding set, so it still uses separate indices for them (and a separate binding set for the immutable shaders like Vulkan used to), so it required some special-casing in the shaders (and adding some webgpu-specific shader compilations). This also removes SAMPLER_MIPMAP which was unused, and renames TARGET_VULKAN to TARGET_SPIRV since that's a more-accurate name Co-authored-by: Josh Jersild <joshua@rive.app>
Rive C++ is a runtime library for Rive, a real-time interactive design and animation tool.
The C++ runtime for Rive provides these runtime features:
We use premake5. The Rive dev team primarily works on MacOS. There is some work done by the community to also support Windows and Linux. PRs welcomed for specific platforms you wish to support! We encourage you to use premake as it's highly extensible and configurable for a variety of platforms.
In the rive-cpp directory, run build.sh to debug build and build.sh release for a release build.
If you've put the premake5 executable in the rive-cpp/build folder, you can run it with PATH=.:$PATH ./build.sh
Rive makes use of clang vector builtins, which are, as of 2022, still a work in progress. Please use clang and ensure you have the latest version.
Uses the Catch2 testing framework.
cd tests/unit_tests ./test.sh
In the tests/unit_tests directory, run test.sh to compile and execute the tests.
(if you've installed premake5 in rive-runtime/build, you can run it with PATH=../../build:$PATH ./test.sh)
The tests live in rive/test. To add new tests, create a new xxx_test.cpp file here. The test harness will automatically pick up the new file.
There's a VSCode command provided to run tests from the Tasks: Run Task command palette.
rive-cpp uses clang-format, you can install it with brew on MacOS: brew install clang-format.
Note that if you‘re on MacOS you’ll want to install valgrind, which is somewhat complicated these days. This is the easiest solution (please PR a better one when it becomes available).
brew tap LouisBrunner/valgrind brew install --HEAD LouisBrunner/valgrind/valgrind
You can now run the all the tests through valgrind by running test.sh memory.
If you want to examine the generated assembly code per cpp file, install Disassembly Explorer in VSCode.
A disassemble task is provided to compile and preview the generated assembly. You can reach it via the Tasks: Run Task command palette or you can bind it to a shortcut by editing your VSCode keybindings.json:
[
{
"key": "cmd+d",
"command": "workbench.action.tasks.runTask",
"args": "disassemble"
}
]
