bjorn 6862b8c970 Change cofactor/normal matrix to mat3; 
This means per-draw uniform data is 128 bytes now!

bjorn 4563959ed1 Rename scratch buffers to temp buffers internally; 2023-04-27 19:15:56 -07:00
bjorn 8f654ed408 Simplify fill shaders; 
Now there's 2 instead of 3!  Behavior is the same, fill goes
layer-by-layer onto each view until either the texture or canvas run out
of layers.

be thick.

bjorn 07a6d11c46 Split vertex animation into multiple dispatches as needed; 
If the number of skinned vertices in a Model doesn't fit in a single
dispatch (~2M vertices on 32-sized subgroups or ~500K vertices on
8-sized subgroups), split it into multiple dispatches.

bjorn 92e9efd882 More flexible Buffer formats; Deprecate temp buffers; 
- Pass:mesh accepts tables for vertices/indices
- Add Pass:setVertexFormat to set format used for table-based meshes
- Pass:send accepts tables for buffers
- Pass:send supports arbitrarily nested structs/arrays for push constants
- Buffer formats support arbitrarily nested structs/arrays
  - Zero-length buffers are valid and represent structs
  - Fields can have names using 'name'
  - Field types can be tables of other fields (structs)
  - Fields can have 'length' key
- newBuffer syntax has been changed to put format first (old version
  still works)
- Buffers can be created from shader variables, avoiding need to declare
  matching format.
- Pass:clear/Pass:read use byte offsets instead of indices
- Pass:copy uses byte offsets when copying a Buffer to a Buffer
- Deprecate lovr.graphics.getBuffer (tables can be used instead)
 2023-03-20 13:54:37 -07:00
bjorn d2b2523306 Improve sampler2D error message; 
- core/spv just returns the type of image variables instead of trying to
  validate them.
- When Shader is loading resources, it will reject combined image
  samplers, uniform/texel buffers, and input attachments, with better
  error messages that include the binding number of the invalid resource.

bjorn 74a9b90e93 Fix zip archive enumeration; 
Zip archives weren't enumerating in the root directory when they were
mounted with a non-empty mountpoint.  Additionally, zips mounted at the
root directory weren't listing files properly.  This fixes both by
normalizing the mountpoint prefix (it had a prepended slash when it was
empty, which messed up hashing), and ensuring there is a "root node" in
the tree with an empty string.

bjorn cacc5eae71 ModelData:getTriangles reuses vertices better; 
ModelData:getTriangles currently adds a fresh set of vertices for every
mesh in a node.  This is technically correct, but it wastes space when 2
nodes reference the same set of vertices with different index buffers,
which is pretty common when a node has multiple materials.  It also
breaks ODE, who doesn't like it when vertices outnumber indices too
much.

bjorn 3775ed1be6 gpu: use distinct allocator/memory for staging buffers; 
Fixes easily-encounterable GPU OOM on discrete cards.

Currently when mapping CPU-accessible GPU memory, there are only two
types of memory: write and read.

The "write" allocations try to use the special 256MB pinned memory
region, with the thought that since this memory is usually for vertices,
uniforms, etc. it should be fast.

However, this memory is also used for staging buffers for buffers and
textures, which can easily exceed the 256MB (or 246MB on NV) limit upon
creating a handful of large textures.

To fix this, we're going to separate WRITE mappings into STREAM and
STAGING.  STREAM will act like the old CPU_WRITE mapping type and use
the same memory type.  STAGING will use plain host-visible memory and
avoid hogging the precious 256MB memory region.

STAGING also uses a different allocation strategy.  Instead of creating
a big buffer with a zone for each tick, it's a more traditional linear
allocator that allocates in 4MB chunks and condemns the chunk if it ever
fills up.  This is a better fit for staging buffer lifetimes since there's
usually a bunch of them at startup and then a small/sporadic amount
afterwards.  The buffer doesn't need to double in size, and it doesn't
need to be kept around after the transfers are issued.  The memory
really is single-use and won't roll over from frame to frame like the
other scratchpads.

bjorn d2ceb6b81a Fix skeletal animation on some GPUs; 
The animation compute shader was not specializing the workgroup size
properly, so it was only working on GPUs with a subgroup size of 32.

The Quest 1 has a subgroup size of 32 and the Quest 2 has a subgroup
size of 64, so this resulted in hand models breaking on Quest 2 only!

A null-char is valid part of Lua string. When such a string is sent

correctly reconstruct it on the other thread.

The bug was triggered with this code:

    s1 = 'a \0 b'
    print(#s1) -- 5
    ch:push(s1)
    s2 = ch:pop()
    print(#s2) -- 2

- They no longer live in temporary memory, but in a dedicated pool.
- There are error checks for using a temporary buffer after it's invalid
  - However, these are imperfect, and could be improved.  One idea is to
    avoid recycling a temporary buffer until its refcount decays (i.e.
    Lua finally decides to garbage collect it).  This would explode
    memory usage sometimes, so it could only be enabled when
    t.graphics.debug is true.

bjorn 0436a5deae Rework automipmapping; 
The sync was totally wrong here.  It's a bit better now.  However there
are some general sync issues that need to be fixed.  Basically a Pass
that does reads and writes or multiple writes doesn't work properly, for
various reasons.  I think sync needs to be split into 2 phases -- first
process all the reads and merge barrier bits into the barrier of the
last writer, then process all the writes and set 'final' resource state
for stuff in the pass.  Due to branch prediction it may be better to
have 2 separate lists -- one for reads and one for writes.  And I'm not
100% sure on how to reconcile a Pass that is doing reads and writes to
the same resource yet, still thinking about it.

bjorn 4ee092e81b Make Pass a regular object; 
It uses newPass instead of getPass.  Temporary objects had lifetime
issues that were nearly impossible to solve.  And normal objects are
easier to understand because they behave like all other LÖVR objects.

However, Pass commands are not retained from frame to frame.  Pass
objects must be re-recorded before every submit, and must be reset
before being recorded again.

Pass objects now provide a natural place for render-pass-related info
like clears and texture handles.  They also allow more information to be
precomputed which should reduce overhead a bit.

It is now possible to request a stencil buffer and antialiasing on the
window and headset textures, via conf.lua.

lovr.graphics.setBackground should instead set the clear color on the
window pass.  Though we're still going to try to do spherical harmonics
in some capacity.

There are still major issues with OpenXR that are going to be ironed
out, and the desktop driver hasn't been converted over to the new
headset Pass system yet.  So lovr.headset integration is a bit WIP.

bjorn c4ff7cca39 Passes track their readbacks; 
There are some issues with immediately tracking readbacks in the global
linked list of pending readbacks:

- The Pass might not get submitted, in which case the readback will be
  "dangling" and never complete (or it will erroneously think it's
  completed but its buffer will contain garbage data).
- Thread safety issues of modifying a global data structure from a Pass.

Instead, Pass will locally track the readbacks it performs, and only at
submit time will those readbacks get added to the global list.

(There is a little bit of refcounting mistakes now, those will get
cleaned up).
