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.
- RGB_11_11_10 is exported in a RGBA PNG file where the 4 channels are
used as a uint32 storing a RGB_10_11_11_REV pixel.
We use the .rgb32f extension, and those PNG files contain garbage
when seen in a PNG viewer.
- This is now the default for the -x option.
- compressed KTX files don't encode RGBM, which means they can't
support HDR, unless an HDR compression scheme is used.

This allows us to skip the CPU-side vector-to-color conversion that
occured at the end, and makes the real-time visualization consistent
with the final visualization.
This replaces the previous "curvature to roughness" method. Both are related
and rely on the screen space variance of geometric normals but this new
solution offers more control (the screen space variance and the clamping
threshold can be controlled).
