If spherical harmonics are not specified in IndirectLight (i.e.
omitted entirely), we instead use the roughness==1 LOD in the shader.
This produce much better results with absolute HDR environment, and
generally works better more often.
This is now the preferred solution.
For cases where spherical harmonicas are better or preferred, they
can simply be supplied as before.
Normally the IOR is deduced from the reflectance, but now we allow to
specify the IOR instead or in addition to the reflectance.
In the later case, it's possible to create physically impossible
materials, but this can be useful for artistic reasons.
This removes a lot of code and will make it easier to migrate into a new
library with Java bindings, etc.
- The clipping planes and projection matrix were unused, removed them.
- In split view mode, our demos were using only 2 of the 3 manipulators,
removed one.
- Instead of callbacks and update methods, users can simply ask for the
current matrix at every frame.
- The manipulator's job is to consume mouse events and maintain an
"look at" basis, there is no need to store a reference to a Filament
Camera.
Fix#1165
In order to use transparent views, post-processing had to be disabled
because we were not able to blit post-processed buffers with blending.
This is now fixed by simply reverting to a quad.
A side effect of this, is improved performance when a scaling blit is
needed when MSAA is active.
This also introduced new "bugs", or at least weird behaviors: the
system needs to know when blending is needed, and this has to be
based on heuristics (unless we add a new api). Currently the heuristic
is that the COLOR buffer is not discarded and the view is cleared with
an alpha value (or not cleared).
- we add an 'intensity' parameter that allows to control the strength
of the AO effect. This is useful for aesthetic reasons.
- the default intensity is now 2x that of before this change, which
makes the intensity parameter match AO papers this implementation
is inspired of.
- bias is now z-dependent, which reduces some self shadowing wrt the
depth.

This removes the samples/envs folder and replaces these KTX files with a
build step that is driven by CMake / gradle / bash, depending on
platform.
This makes it easier to use IBL files that are generated by the latest
and greatest version of cmake.
We use R11F_G11F_B10F for HDR so we should stop checking for compressed
IBL files.
Also, make the glTF sample on web more consistent with the default
settings used by gltf_viewer on native and use venetian_crossroads
instead of syferfontein.
We now build three gltfio libraries:
- gltfio_core ....... lightweight library with ubershaders
- gltfio ............ uses filamat to generate materials at runtime
- gltfio_pipeline ... depends on path tracer functionality
This uses strtof rather than stringstream and provides a common location
that can be leveraged by the upcoming JNI bindings.
Note that this new method lives in KtxBundle rather than KtxUtility. The
latter creates Filament textures and therefore does not get built into
libimage.
This adds a utility function on IndirectLight populate the reflection
map from an environment at runtime. This performs some processing
similar to cmgen, albeit at a reduced quality.
In commit d955e73 we changed the default IBL from RGBM to RGB, but we
kept its internal format of RGBA8. Since the internal format is not
compatible with the data format, we see GL_INVALID_OPERATION during the
texture upload.
This is a single-pixel black texture, so the format does not really
matter, but this clears up a GL error seen on some platforms.
