Would it be possible to add Doom Gles features

[SanyaWaffles]

GZDoom has an OpenGL ES renderer.

He refers to an ancient, arcane and abandoned alpha sourceport by kokak. I don't even know what "realistic water" is.
I dunno what to say but i guess Graf would say NO.

That makes slightly more sense I guess. I kind of wish that was specified a bit more clearly.

you should play the source port to see the features

Now i see there's a beta. But this was for pocket pc (i see it was a windows pda) and some features are exclusive to the nvidia goforce 5500 (not geforce). Y wenas.

Not really the issue I had with your post.

Just to be clear with the official stance on this post:

Yes, no, maybe. You aren't specific about what ones, some are doable, some are not. We can't read your mind and we are just hobby developers who do this in our free time, at the end of the day it really depends on how easy it is to implement and how useful/desired the feature actually is. But if you don't throw us a bone and give us specifics, the answer most certainly will be [No]. And even when it's not, it really depends on how interested someone is in the feature who has the skill to implement it and how useful they think it would be (or how cool they think it would be to have as is the case sometimes).

What OP likely is referring to is the eyecandy bits of DoomGLES - the lensflare, the shadered water, and so on.

DoomGLES for PocketPC was basically Doomsday in terms of eyecandy. It was fun to see running on PPC (I actually have a device that could run this properly, the Dell Axim X50v) - but nowadays, why bother.

I always was interested in the rippling reflection water effects.



Also reminds me of a similar effect for deep-water sectors from Legacy that I don't think we ever got.

Wenas. Turns out there's a more modern paid version for android (1.4?) but it's not on google play anymore. And there's no source code.
There's an outdated homepage.

I found the apk here (it says d-gles demo?) and i think the webpage is legit.

It doesn't work and it says d-gles tech demo, i don't know what that means. There are some options and a splash screen, then you hear some music and get a black screen.

Starting with V1.3, OpenGL textures are automatically generated (ETC format) and the music is directly played from the wad in MIDI format.
Most of the textures are generated at the first level you launch. Depending on your device it may take a while (it hasn't crashed, please be patient). Also, as this conversion is very time consuming, the textures are in medium quality.

I don't think i need to download the pre-computed packs or wait, there's no menu and i hear music. My device has a MediaTek Helio A22 MT6761 with 2 GB of ram, PowerVR GE8300 and android 11 go.

Obviously I'm a fan of that effect.
I wonder if it might be something that could be achieved, or approximated, with shaders these days?
i.e. as a mod/add on, not necessarily a core feature.

It stands for Doom GLES tech demo. Its a demonstration of the engine. It likely is compiled for an ancient Android installation.

AFAIK the GLES stuff under Android is done with GLES 2.0, and the older stuff, relying on PowerVR tech, uses the tile-based approach. The Goforce version used a pixel shader, however.

Then is it a demo or the full engine? xD
It should run with gles 2.0 but it doesn't. If doubt @emile_b is interested in adding the features. Y wenas.
