This removes a lot of heap allocations/deallocations, and reduces
code size. Most improvements come from using CString and
StaticString instead of std::string and better using move
semantics.
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.
- move UBO declarations in UibGenerator, i.e. next
to their Uniform Interface Block definition.
This should help forgetting to update one but
not the other.
- move UniformInterfaceBlock.h and SamplerInferfaceBlock.h under
private/filament/.
- do the same things for samplers
* 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
