This changes the WebGL and desktop glTF viewers so that they always
call `updateBoneMatrices`, even when there are 0 animations. Note
that our Android sample was already doing this correctly.
When combined with #5301, this fixes#5299, although users would need to
use the `recomputeBoundingBoxes` feature in gltfio (`-r` in the desktop
viewer) for this model to be scaled to fill the viewport, since its
embedded bounds are quite large.
This fixes the emscripten binding errors that we've been seeing
with the <filament-viewer> test page, which prevented us from
including web in the last few Filament releases.
The binding errors were caused by double-initializing the emscripten
module.
I fixed this by allowing clients (e.g. FilamentViewer) to call
Filament.init() more than once. We now accumulate a list of "on ready"
callbacks that get triggered after the emscripten module becomes ready.
As far as I can tell, multiple canvases were actually always broken, and
the viewer test page worked in the past only because we got lucky.
The previous code would convert each element of the source data
into 8 bit-per-element, but we wnat to preserve the original format
that the user provides.
The new solution is to use `slice()` which is a robust way to clone
all the data in a typed array.
This fixes the new regression with Triangle that Ben caught.
If emscripten grows the heap inside one of our BufferDescriptor binding
functions, then the old heap becomes "detached" and an error can
occur.
This fixes the issue seen with the Parquet demo that Ben caught.
Support legacy morphing (morphing with targets supplied via VertexAttributes) for older clients. This gives clients more time to transition over to the new MorphTargetBuffer API.
* mipgen: Linearized PNG bitmaps (such as normal maps) no longer perform gamma transform on read.
* mipgen: Using "-k normals" argument now works for all file types, not just KTX
* Web: Exposed SurfaceOrientation functions getQuatsHalf4() and getQuatsFloat()
Currently there are 8 light channels, both renderables and lights can
be associated to one or several light channel, lighting occurs when
at least one channel is active on both the light and the renderable.
Fixes#4275
We now have an option for evaluating the bent normals from SSAO.
This is used to improve specular AO.
Currently these bent normals are not used for diffuse lighting because
they're "flat" (face normals), which is too distracting.
The bent normal buffer is stored in the SSAO texture, in a separate
layer. This is the first post processing effect that uses 2D array
in order to limit our sampler usage.
This CL also changes how we handle SPECULAR_AO_BENT_NORMALS when
material bent normals are not available: we're now using the "Cones"
algorithm with the regular normal, instead of Lagarde's approximation.
