This is used by our upcoming gltfio library and is the lightest-weight
glTF reader that we know of. In fact it does not do much other than
parse the JSON and provide C structures for the data.
Assimp's CalcTangentSpace deviates from de facto glTF 2.0 so we were
compensating for this with an unconditional fixup in MeshAssimp. However
the fixup should apply only when CalcTangentSpace is active, i.e. when
the model is missing tangents.
This makes it so that NormalTangentMirrorTest (has tangents) and
NormalTangentTest (needs tangents) both look reasonable.
I also noticed that MeshAssimp was inexplicably applying
aiProcess_CalcTangentSpace twice: once as a flag, and once as a
post-process. I removed the latter.
This will be fixed in the upcoming cgltf-based loader, which will
use our officially-sanctioned utility method in VertexBuffer.
See #528
This is a more complex test than suzanne because it has multiple
materials and exercises the named materials functionality in
loadFilamesh.
This also exercises our glTF-to-Filamesh pipeline at build time.
See issue #663
* Improve rendering to TextureView
UiHelper wasn't calling the resize callback at init time when attaching
to a TextureView, but it was for a SurfaceView. This makes both code
paths consistent and fixes the standard samples if they are modified to
render to a TextureView.
This change also adds a new sample app that shows how to render into
a TextureView.

This also adds it as a dependency to filameshio. This does not seem to
increase the size of the WebGL build even though filameshio is a
dependency, perhaps because we are not using it yet.
Since we use this for decoding, this adds a dependency to the core
filament renderer which in practice is only used for Vulkan. However
this is a tiny library, so it's simplest just to always include it.
The next PR will add the actual compression / decompression code to
filaflat and filamat. Here are the preliminary results.
102K => 29K aiDefaultMat.filamat
102K => 29K aiDefaultTrans.filamat
21K => 5.0K bakedColor.filamat
22K => 5.2K bakedTexture.filamat
21K => 5.0K depthVisualizer.filamat
40K => 10K groundShadow.filamat
102K => 29K sandboxCloth.filamat
125K => 36K sandboxLit.filamat
126K => 36K sandboxLitFade.filamat
126K => 36K sandboxLitTransparent.filamat
109K => 31K sandboxSubsurface.filamat
21K => 4.9K sandboxUnlit.filamat
21K => 4.9K transparentColor.filamat
Both the "before" and "after" numbers are excluding non-Vulkan targets,
and I also changed our CMakeLists to build filamat instead of inc.
This was designed as a standalone tool rather than a library, so we are
renaming their "main" function to "standalone_main", which is described
in the tnt README.
We'll also be adding a wrapper to our imageio library.
- cmgen now creates reflections maps for all input
assets by default instead of just for equirectangular
images.
- equirectangular decode doesn't mirror -- that's
done by the mirroring code now.
- mirroring can be turned of with --no-mirror
- option --mirror is gone
- faster mirroring code (do it before generating
mipmaps)
- added labels to faces of debug.png environment
- added a debug equirectangular image in third_party

This implements the following suggestions from Adam Sawicki:
(1) Update VkMemAlloc to dev branch.
(2) Use VMA_MEMORY_USAGE_CPU_ONLY in the stage pool.
(2) Add vmaFlush after every vmaUnmap.
We also considered removing Map / Unmap in favor of persistent mapping
via VMA_ALLOCATION_CREATE_MAPPED_BIT, but decided to be conservative
until we have a chance to rethink our UBO update strategy.
Closes#19
* Update SPIRV libraries
- Update `spirv-cross`
- Update `spirv-tools`
- Update `glslang`
`spirv-tools` contains a fix for an issue we reported (unnecessary promotions to highp in certain expressions).
* Add SPIRV-Tools dependency to matinfo
