* Add support for transparent shadows
This solution uses an 8x8 Bayer matrix. We could find a better
noise. We also need better filtering of the shadow maps. A PCF
is barely enough and VSM fails without blurring.
* Use a fixed Bayer matrix, fix pre-caching of depth shaders
* Use gradient noise instead of fixed bayer pattern
* Update docs
* Improve materials under white furnace test
Two major changes:
- Mobile target now implements a cheaper variant of the off specular
peak bias (which moves the reflected vector towards the normal).
This greatly helps with rough surfaces that may otherwise point
toward a bright part of the IBL.
- The indirect diffuse love is now properly attenuated to avoid adding
the energy reflected by the specular layer. This allows dielectrics
to be correctly energy conserving under a white furnace.
- Tweak the (hacky) clear coat layer attenuation to behave properly
under a white furnace.
* Use the same reflected vector modification everywhere
* Add screen and multiply blending modes
This change also fixes a sorting issue: different sorting modes
were sorted in different buckets which is incorrect. We want
to sort only by distance.
* Update release notes and Java API
* Fix build error
* Add build command for Markdeep files
build.sh -w can now be used to "rasterize" Markdeep .md.html files
to regular, static .html files. These files load faster and do not
suffer from an initial flash of uninitialized content.
This new command requires node, npm and nx to run puppeteer to
"rasterize" the Markdeep documents. This should eventually be
integrated in the actual build system to automatically re-generate
the HTML files when the Markdeep documents are edited.
* Remove unnecessary .gitignore file
* Change constant names for JS docs
