This tool can be used to replace inc files for built-in materials. The
inc files are unfriendly to IDE's and do not extend to non-material
resource types such as baked texture data.
The tool aggregates a sequence of binary blobs, each of which becomes a
"resource" whose id is the basename of the input file. It produces the
following set of files:
resources.h ......... declares sizes and offsets for each resource
resources.S ......... small assembly file with incbin directive
resources.apple.S ... ditto but with different rodata name
resources.bin ....... the aggregated binary blob
resources.c ......... large xxd-style array (only for WASM)
We did an experiment to test the incbin directive on a variety of
platforms in PR #510.
This change also optimizes the size of existing images using squoosh.app.
This should make the main README a lot lighter and faster to load (it saves
several MiBs).
This does not add any samples or continuous integration, but it at least
allows developers to do a "-p webgl" and check if an actual wasm file
for the core Filament library can be succesfully built.
* Introduce mipgen frontend.
For now this is fairly simple although it does let you choose a filter.
Another cool feature is that an HTML file is generated which makes it
easy to review the generated miplevels.
This does not expose the Boundary enum to users because it has not yet
been implemented in the core Image library.
* Fix up mipgen per code review.
* Overhaul the image library, Phase I.
The preps for our upcoming mipgen command line tool by adding filtering
capabilities and unit tests for a new LinearImage class, which will
subsume Image (deprecated).
Filament's new image library is composed of three components:
- LinearImage....simple 3D tensor of floats
- ImageOps.......free functions for simple transforms
- ImageSampler...high quality filtering
The old Image class was a simple untyped data blob and is now
deprecated. The new LinearImage class is always float32, and always
stores pixels in packed scanline order. This makes it easier to
implement image-based algorithms because they can be agnostic of the
underlying format.
Remaining refactorings:
- Phase II will migrate imageio to LinearImage
- Phase III will migrate all downstream tools to LinearImage
- Phase IV will remove old the Image class
* Image library code review feedback.
* Update build instructions
* Compile shaders in a separate static library
Each shader string is now part of a separate .o file, which should make recompiling filamat/matc a tad more enjoyable.
* Shaders.h belongs to filamat, not filament
