bjorn 6cfbfd050d Fix issue with synchronization; 
If there is only a single pass in the submit, barrierCount is zero
since there will be no inter-pass synchronization.  This is almost
correct, but not quite, because if a Pass has compute and render work,
the render pass may need to synchronize with the compute pass.  So a
barrier is still necessary.  For simplicity, always allocate the full
number of barriers, even though the final render barrier will always be
empty.

Additionally, avoids passing NULL to memset when the barrier count is
zero and the barrier arrays are NULL.

bjorn 6e12370ee8 Fix out of bounds access in newShader; 2023-10-05 11:26:43 -07:00
bjorn 2a3b517334 Fix incorrect depth buffer default in Pass:setCanvas; 
If you did newPass(texture) instead of using a table, the pass would not
have a depth buffer instead of using d32f.

bjorn e307487041 Pass:send supports single booleans for push constants; 
vectors/arrays/structs with booleans still aren't supported.

bjorn 44b250a517 Fix issue with texture readback layer count; 2023-10-04 13:12:55 -07:00
bjorn 327b1954ea Readbacks with nesting always use key-value format; 2023-10-04 09:00:36 -07:00
bjorn 805b83601f Buffer readbacks use a more consistent format; 
- Always wrapped in table
- Length is always item count
- Scalars are tables of numbers { 1, 2, 3 }
- Vectors are wrapped in tables { { 1, 2 }, { 3, 4 } }
- Compound formats are wrapped in tables, like Mesh vertices
- Structs/nested types are tables

bjorn 842df4b305 Fix buffer readback issues; 2023-10-04 08:52:05 -07:00
bjorn c976b36682 Buffer:getData takes optional index/count arguments; 
Also, the Buffer needs to have a format.
 2023-10-04 08:52:05 -07:00
bjorn 86db0e3ab5 Buffer:getPointer is renamed to mapData; 
It also takes range parameters.

:getPointer is deprecated.

bjorn cf744ace83 tup: add MSDFGEN_PUBLIC define; 2023-10-03 11:17:06 -07:00
bjorn f0686f0115 Update msdfgen; Orient contours properly; 
This fixes issues where some fonts would have glyphs with weird windings
and they would get rendered inside-out.

Unfortunately updating msdfgen increased its size by a factor of 2-3x.

bjorn 3041a9a484 Pass:setTallyBuffer(nil) works; 2023-10-02 10:49:54 -07:00
bjorn 9a276e5f9a Tally fixups; 
- rm :getTallyData, it's totally lame, just do a readback
  - rm gpu_tally_get_data too, webgpu doesn't support it anyway
- Clamp tally copy count so it doesn't overflow buffer
- Tally buffer offset's gotta be a multiple of 4
- Return nil instead of 2 values when tally buffer isn't set
- Copy correct number of tallies (multiply by view count instead of max
  view count)
- Skip occlusion queries entirely if no tally buffer was set

bjorn d7c6461916 Render targets with mipmaps get transfer usage; 
Also I think no mipmaps is more sane default for render targets.

bjorn c3b99a397a Mesh bounding box uses same convention as everyone else; 
It was using

minx, miny, minz, maxx, maxy, maxz

Instead of

minx, maxx, miny, maxy, minz, maxz

bjorn c3c5284f11 Improve viewport/scissor accessors; 
- Better validation
- Can set to nil to "disable"
- Getter returns nil when "disabled"
- Negative viewport height works again

bjorn 3fb3590b77 Mat4:mul/Quat:mul return temp vectors; 
Quat:mul also takes numbers.
They both require 3 args when using numbers.
I didn't opt for the 4-component Mat4:mul(numbers) variant, mostly out
of laziness.

bjorn 6883c36397 Rename Mat4:getTranslation/Rotation -> position/orientation; 
It's a little less correct, but literally everything else is
"getPosition" and "getOrientation".

bjorn fbdecda440 Render textures have mipmaps by default again; 
They defaulted to 1 to avoid confusion when mipmaps weren't generated
during a render pass (withou the { mipmaps = true } flag), but now the
mipmaps flag is obsolete and render passes automatically generate
mipmaps for all levels in their texture views.  This means that render
passes can have mipmaps by default again, which leads to better
appearance when sampling them later.

bjorn b03e3244c3 LÖVR no longer requires 64KB uniform buffers; 
Due to per-draw data size reduction from 144 -> 64 bytes.
