[shaders]Bloom + Better Light

[LMD]

OKAY ! Invitation : https://github.com/appgurueu/new-shaders/invitations

[Skulls]

I'm in! Thanks, LMD.

Alright folks, wish list time for shaders. Colored lights, speed, super fancy psychedelic rainbows, have at it. I can promise that 99% of it won't be worked on. But it will really help set priorities.

The goal will be get it into the main Minetest branch so a history of well tested, stable, and documented code is needed. It also has to make the game better for all players, not just those who want to enable fancy graphics.

shaders are good and all, Skulls and LMD, but you guys are still going to need the minetest client to have the features necessary.
however there are two PR's that implement everything that is necessary:

https://github.com/minetest/minetest/pull/6839
https://github.com/minetest/minetest/pull/5913

For lighting with lots of light sources, you could look into light cuts.

[ThomasMonroe]

what do you mean light cuts?

hmm that seems to be for rendering a photo-realistic scene rather than a game scene

I don't see why it couldn't be used for Minetest's light levels, since it doesn't seem like lightcuts are that expensive to compute, and Minetest's lighting doesn't change that frequently. The core of the paper is just an algorithm that approximates a bunch of point lights using less lights.

Sweet, thank you. LMD, lets pull this into a branch and start poking around. Still need to do the testing and boring bits.

[ThomasMonroe]

kilbith's PR still has work to be done with it though

[Skulls]

Moar shaders I stumbled across, for the curious: https://github.com/armory3d/armory/tree/master/Shaders

[LMD]

Post processing is pretty nice, and not much work to implement, as theres already the mentioned base. Here is a good point to start. https://github.com/minetest/minetest/pu ... a8fc8c0be1

EDIT :
Skulls, I need your help. How can I fork this PR ?

[Skulls]

I can't figure out how to do that using the GitHub web interface but if you clone numberZero's repo, switch to the dev-postprocessing branch you should get there. This will have to be done on your local drive.

[ThomasMonroe]

Skulls..most of the shaders you have found may not be able to be implemented due to the client, however they will be very instructive.

[LMD]

Based on numberZero's impressive work :
https://github.com/appgurueu/new-shader ... gment.glsl
Edge darkening
Focus blur
Thanks alot, numberZero !
EDIT : TESTERS REQUIRED !
If you want to test the new post-processing :
- compile numberZero's minetest fork with post-processing
- replace opengl_fragment.glsl in client/shaders/post-processing with my version.
- you may also replace opengl_vertex.glsl, but this is not necessary.
azekill_DIABLO : Je pense que tu es un personne qui a plein d'experience avec "compiling Minetest" et que tu peux faire ca tres bien, et je crois que tu aimes essayer des nouvelle choses le plus de tout la monde. Est-ce que tu es d'accord ?
PS : J'apprends le francais depuis 2 ans a mon ecole.
Et je sais que je n'ai pas utilise des accents, c'est parce-que ca n'est pas facile avec la clavier de mon ordinateur allemand.
Any feedback ?

[ThomasMonroe]

it seems that all of the rendering code was rearranged and better organized, so numberZero's work is no longer valid and needs to be re-done with the new rendering implementation.

[LMD]

The only word that fits well now has 4 letters and starts with s.
Guess what ?

[ThomasMonroe]

Sorry, I don't have enough C++ knowledge to implement this yet, however you could search around and try to find someone willing to pick it up.

[LMD]

Anyway, we can test the shaders with his Minetest fork.

[LMD]

I have ANSI C99 experience. And Java experience. Equation : C99+Java = C++
But I have no MT experience. ß((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((
We need a core developer.

[azekill_DIABLO]

mmm... ask paramat maybe.

[rubenwardy]

I doubt you'll get much help from paramat. numberZero or lhofhansl would be more likely to be able to help you.

[ThomasMonroe]

yeah paramat isn't much into eye-candy/graphics, he's more of a MT mechanic than anything else

[TumeniNodes]

yeah paramat isn't much into eye-candy/graphics, he's more of a MT mechanic than anything else

Working with shaders is not an easy task..., by any means.
It's not so much that he isn't into eye candy, I would say more like not experienced in that area..., same goes for the rest of the devs or, I assure you..., there would be more to offer by now.

And it is not very easy to find individuals who are, who would be willing or available (time wise) to work on it for free.

[ThomasMonroe]

touche
however paramat has said on multiple occasions that he is not a big fan of eye-candy. But like you said, that doesn't mean anything, all it takes is someone experienced in shaders.
