bjorn 880d06a1d1 Only enable compute extensions on desktop GL; 2021-02-19 14:09:40 -07:00
bjorn 1757d30a59 Compute shader feature detection adjustment;
- Compute feature requires compute shaders, image load/store, and SSBOs.
- GLSL 330 is always used, instead of changing depending on compute shader extension.
- Explicitly enable compute shaders, image load/store, and SSBO extensions when needed.

This allows implementations that don't support GLSL 430 to run compute shaders,
and keeps the min supported GL version more consistently at GL3.3.

bjorn 08916df2f1 Tell spatializers about sources only when they're active;
apply will still only be called with sources after they have been created.

bjorn 952fee3bd1 Rework audio converters;
They are stored by value in the array so they are contiguous.

Source stores the index of its converter to save a bit of space and avoid realloc.

bjorn 75fda2336f Enforce strict limit of 64 active sources;
If 64 sources are playing and a new one is started, Source:play will
return false.

Instead of a linked list, a static list of 64 Sources is used.

Bit scanning intrinsics are used to efficiently iterate the list,
using a mask (still deciding on this).

mcc 9ba4037e74 LOVR_USE_OCULUS_AUDIO
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.
