dx was deprecated years ago, and d8 replaces it. dx is
removed in build-tools 31, so it's best not to depend on it.
In addition, d8 now supports Java 11 (class version 55), which
is required to use the javac bundled with Android Studio.
So that projects that use lovr as a submodule can
inject their own plugins.
By picking them up from the _root_ project, whatever project that
is embedding lovr can decide for itself what plugins to use. This
is cleaner than using a separate glob and a variable in the case
where lovr will never come bundled with a standard set of plugins.
A previous change modified the rpath to always be @executable_path.
This patch moves all libraries next to the executable, so that they can
load properly with the new rpath. For better organization, everything
is nested into a bin directory. This is congruent with how linux works.
Bundled builds remain the same -- they are using @executable_path like
before, and libraries get moved next to the executable inside the .app.
It uses a deprecated version of CMake, creates weird directories,
is slow to compile, and causes tup to rely on CMake more. Instead,
just use its binary artifacts directly.
This is a large patch which adds a new Oculus Audio spatializer. Oculus Audio is slightly different from the dummy spatializer in a few ways:
- It *must* receive fixed-size input buffers, every time, always.
- It can only handle a fixed number of spatialized sound sources at a time.
- It has a concept of "tails"; the spatialization of a sound can continue after the sound itself ends (eg echo).
Changes to audio.c were needed to support Oculus Audio's quirks:
- audio.c now supports a "fixedBuffer" mode which invokes the generator/spatializer in fixed size chunks
- Each source now has an intptr_t "memo" field that the spatializer may use to store whatever (Oculus spatializer uses this to handle the sound source limit).
- The spatializer interface got a couple new methods: A "tail" method which returns a sound buffer after all sources are processed; and "create" and "destroy" methods that are called when a sound source is created or destroyed (Oculus spatializer uses this to populate/clear the "memo" field).
Along the way some other miscellaneous changes got made:
- lovr.audio.getSpatializerName() returns the current spatializer
- Spatializer init now takes in "config in" and "config out" structs (Spatializer changes fields in config out to request things, currently fixed buffer mode).
- lovr.conf now takes t.audio.spatializer (string name of desired spatializer) and t.audio.spatializerMaxSourcesHint (Spatializers with max sources limits like Oculus will use this as the limit).
- audio.c went back to tracking position/orientation as vectors rather than a matrix
- A file oculus_spatializer_math_shim.h was added containing a minimal copypaste of OVR_CAPI.h from Oculus SDK to support a ovrPoseStatef the spatializer API needs. This may have license consequences but we are probably OK via a combination of fair use and the fact that a user cannot use this header file without accepting Oculus's license through other means.
Some work remains to be done, in particular there is an entire reverb feature I did not touch and LOVR_USE_OCULUS_AUDIO cannot be activated from tup. Oculus Spatializer works better when it has velocity and time information but this patch does not supply it.
- Linux rpath is changed to $ORIGIN
- Libraries (shared libraries and plugins) are copied to executable.
- Executable is output to bin dir for easier packaging.
Need to look into consolidating the move_lib functions for each platform.
- Link against dl (this was probably why ffi.load didn't work)
- Store shared libraries in the apk uncompressed
- Libraries are added during the "package" aapt call instead of "add".
- Because -0 (used to store uncompressed) only works during package.
- classes.dex is added here too now.
- There's only one aapt invocation now, which is kinda nice.
- The lib folder needs to be in a subfolder now ("raw" was chosen).
- Because "package" and "add" subcommands work differently.
- Store shared libraries in the apk page aligned
- Required passing -p to the zipalign invocation.
- This is needed because dlopen("zip!path") needs it.
- android:extractNativeLibs="false" is added to the XML manifest.
- apk sizes are bigger, but disk usage and install time should improve.
- Fix a bug with moving plugin libraries into the lib folder with CMake.
- Use lovrFilesystemGetSource instead of lovrFilesystemGetExecutablePath
to get the proper path to the apk.
- The plugins folder can contain native plugins.
- CMake will build plugins with CMakeLists in them
- They can check the LOVR variable to see if they are being built inside LOVR.
- They can set the LOVR_PLUGIN_TARGETS variable to a list of targets they build.
- If blank, all non-imported targets added in the folder will be used.
- The libraries built by their targets will be moved next to the executable or into the apk.
- The library loader now tries to load libraries next to the executable or in the APK.
- It is "fixed function" now, this may be improved in the future.
- The lovr.filesystem C require path has been removed.
- enet and cjson have been removed. Use plugins.
stb_image's vertical flip flag was not thread safe in the version
of stb_image we were using. We patched stb_image to use a thread
local variable for the flag. stb_image has since been upgraded to
expose a thread local version of the flag, so our patch is no longer
necessary after upgrading.
The CMake flag to enable the thread local patch did not make very much
sense because thread local stuff is unconditionally used elsewhere.
This prints a warning but it's nice to not build the luajit executable.
Ideally the target would not be created at all but the CMakeLists we
are using does not expose this as an option.
This is congruent with the vanilla Lua build options.
- Make the renderloop synchronous by hijacking the RAF to run on the
XRSession when active.
- Convert os_web to use emscripten's native HTML5 interface instead
of going through GLFW.
- Stop using preinitialized GL context -- lovrPlatformCreateWindow
now creates the context.
- GLES2/3 emulation is not necessary.
- Remove inline sessions. The VR simulator is used to render to the
Canvas instead. webxr_attach and webxr_detach are used to replace
replace the active headset driver with the webxr driver when an
immersive session starts.
- Add noop desktop_getSkeleton.
