(+/-)\n\n* store normal as Oct16, based on [A Survey of Efficient Representations for Independent Unit Vectors](http://jcgt.org/published/0003/02/01/) ~ 2014\n* use [Scalable Ambient Obscurance (SAO)](http://graphics.cs.williams.edu/papers/SAOHPG12/) ~2012 (I adapted G3D shader from sample), including blur (H+V)\n* lights are defined as geometries + use stencil buffer to restrict area of effects.\n* use material Id (+ table) to define some materials (diffuse, ...)\n* display intermediate data textures (to help for debug) :  normals, depths, matIds, materials table, ao,\n\n# TODO\n\n* generate final result\n* add more kind of lights (points, spotlight, directionnals, ambiants) (WIP)\n* add \"brdf\" lighting\n* try accumulated light buffer (ignoring material/surface)\n* add NPR samples\n* optimisation\n  * profiler (jvisualvm, mat, ...)\n  * bench : via [jmh](https://github.com/melix/jmh-gradle-plugin)\n* clean-up\n* modularize shader to ease reuse, customisation,...\n* basic documentation (README, usages)\n* provide doc/sample how to\n  * change lighting function\n  * add light type\n  * extends GBuffer to store additionnal data\n  * extends MatIdManager to store additionnal data\n* add shadow\n  * cast-received shadow (hybrid map + volume) ?\n* try [mssao](http://www.comp.nus.edu.sg/~lowkl/publications/mssao_cgi2011.pdf)\n* use deep GBuffer based on \n  * update SAO\n  * add  pseudo-radiosity (??)\n  * add Motion Blur\n* a lot of more ...\n* support env without depth24stencil8, some ways to explore :\n  *
