update 2019 (actual in 2020)
gitlab mirror https://gitlab.com/danilw, untill I can update github repo I will (depends of github rules(region block) updates based on U.S. laws)
what is it random(mosly some very broken demos, and very unusable utils) code I write using Godot. I do not recoment use this code for learning.

new 2020:
graphic_demo_3d using simple custom shaders in Godot 3.2.1, like Area lights, all used external-code/logic linked in each shader, if used. Used Godot 3.2.1 stable, without modifications.
Used two models with animations from sketchfab, links in USED_ASSETS_LINKS.md
try it live(WebGL2) or download on itch click demo link
Video youtube link
Godot has bug with EXR/half_float, in WebGL2 build.
To avoid it - edit scene Area lights2, mesh floor its material, remove ltc_mat, and ltc_max linked textures. Then edit floor.gd script on same mesh, uncomment line 20 load_from_data_v2()
License - my code do not have any licence, use it as you wish. External used resource linked in each shader if used. Some of shaders and two character models has CC non commercial license.
Volumetric_Lights GLES2 Volumetric lights for Godot 3, very minimal example. Shader logic do sample depth from light source, in main-camera view. Shader not very hight cost. Shader can use 16 or 32 sample steps. Used unmodified Godot 3.2-stable.

links Live web build (WebGL2/GLES3), Win64 GLES2, Win64 GLES3
WebGL GLES2 this project does not work in GLES2-Web build, because WebGL do not allow write to depth. I build it in GLES3(WebGL2) Godot web-build.
AMD GLES2 bug if you see this(image link) then you need use GLES3 only, bugreport to Godot, bugreport to AMD.
Licence: Volumetric_Lights code, include shaders do not have any Licence. No licence. Use it as you wish.
to remove Disk behind objects read line 57 in shaders/vulume_lights.shader and set depth_mult value to 10 if you need. This Volumetric light good if you put it inside of something, like box or sphere, light from flat objects does have limitations.
portals_panorama GLES2 scene with six very simple procedural panorama for godot. Shader source code in panorama/shaders folder.
Video youtube link
links Live web build, Win64, Linux64
Support: Godot 3.1, Godot 3.2, GLES2 or GLES3. Used official Godot build, nothing else.
How yo use in your project: create MeshInstance, mesh Sphere, in mesh check flip faces, create shader material, in shader code copy-paste any of *.shader code form this project. (for advanced use look this project source)
Portals they are bad, they exist only for this demo-scene. Portals rendered with huge-overhead because Light Cull Mask not implemented in Godot 3.x versions.
Used external resources: I have use external resources, list of used 3d models, and original shader-source linked in each *.shader file.
Licence - my code do not have license, use as you wish. Used some external shaders, that has CC-NonCommercial license. Check linked resource in each shader linked used resource.
old 2019:
flat-maze demo base on particle collision, that show more complex collisions. link to repo https://github.com/danilw/flat-maze playable web version https://danilw.itch.io/flat-maze-web
Video youtube link
particle_self_collision very simple GPU collision for thousands Indexed-particles, each particle with own index and other unique data, on GLES3/WebGL2, using Godot. live(web) demo link , or download for Win64(exe)
this is GLSL-only logic, example on shadertoy https://www.shadertoy.com/view/tstSz7
Video youtube link
Building: you need rebuild Godot with enabled GL_RGBA32F suport, read this page there building howto
Menu_2DGI rendering static textures and use them as menu textures, include render and examples.
To edit max number of shapes (is 5) edit const max_elems in scene.gd, and int max_elems in 2dGI.shader. (used default Godot 3.1.1)
How to use watch video.
Web version, live Examples: Smooth color example. Minimal examples 1 2.
Download bin:Render for Windows or Linux. Examples example 1, 2, 3
e-ani link to repo with source code https://github.com/danilw/e-ani playable version download from https://danilw.itch.io/e-ani
a_rel_bw_game Warning: code very bad! || Using lots of particles in Godot, in small demo-game. To build this project you need build Godot with module futari-addon (google it(gitlab) ot use this link ) Binary versions: win64 linux64 live/web(work only in Firefox reason) (native builds have Mipmap On, web build off)
Dynamic sky and reflection two shaders for sky and reflection video, live link and windows version
mipmap forced bug(Godot 3.2) to fix it and have sky as panorama, add iChannel.flags=Texture.FLAG_FILTER in scripts/set_uniforms.gd (line 8) after var iChannel=sky_b.get_viewport().get_texture()
Environment bug(on first load): Godot has bug with removing Default Environment after re-import Assets(project is work if launch, it does not work only in Godot editor), set Project->Projet Setting->Rendering->Environment->Default Environment select file default_env.tres
GLES2 version of this Sky only web build GLES2 link for test download source project Dyn_Sky_only_GLES2.zip
