Feature request: Add a switch between different render backends #59

artdeell · 2020-04-04T16:37:15Z

I have an idea: because ~40% of Android 7 devices are supplied with Vulkan drivers, and in some cases Vulkan will be more performant than OpenGL ES, you would try to create a switch, that will change wrappers:
Current GL4ES or
Zink (as Mesa driver) or
Software rasterizer (if your device is Core i9-9900k witk VGA 256-color GPU and Android-x86)

I can try to help you with adding Mesa(for Zink) natively to your project, but i don't know how to implement a switch.

If you're heard about Mesa only as a software rasterizer, you can read the Mesa's wiki.

Zink is an efficent Vulkan-to-GL wrapper written in a form of Mesa driver. It emulates OpenGL 3(!), and knows how to convert shaders. Zhuowei Zhang already tested it with Boardwalk,
but that version was never released.

khanhduytran0 · 2020-04-04T23:17:00Z

Software rasterizer (if your device is Core i9-9900k witk VGA 256-color GPU and Android-x86).

No, i only have Core I5 8250U (1.6ghz, laptop), and 4gb ram so this is why I dual-boot instead of install emulator.

I had take a read at Zink but don't know how to create a switch, or set LD_LIBRARY_PATH???
LWJGL load only libgl04es.so so if libzinkgl.so or something LWJGL can't find, so need to create 2 different liblwjgl.so

artdeell · 2020-04-05T06:39:22Z

And switch between them.

artdeell · 2020-04-05T06:42:31Z

Hm. I have a better solution. gl4es generates LibGL.a and Zink generates LibGL.a, so we need to (for example):

Read a text file with library name
Load that library

In C++ you somehow can load libraries dynamically, so this will be a solution.

khanhduytran0 · 2020-04-05T06:49:21Z

Harder than you think, I must add a custom SurfaceView and some JNI Bindings for Vulkan, need some modify in LWJGL to toggle dlopen() between two different path/name...

artdeell · 2020-04-05T07:12:28Z

Do not use Zink because it's a part of Mesa driver, that can't be embedded into a standalone app.
If you're lazy, you can just have two separate releases: Vulkan release and OGLES release.

Also, take a look at this https://github.com/p3/regal
It's compartible with OpenGL 4!

It's pretty old (last commits made 5 years ago), but it's natively compartible with Android(not as Mesa, which is compartible only with Android-x86)

khanhduytran0 · 2020-04-05T13:41:27Z

Look at the answer of your question
zhuowei/Boardwalk#363 (comment)

Edit: there's also Regal, which definitely won't work for Minecraft 1.14 and below (no display list support), but might work for 1.15.x and above. I'd try that as well.'

But i will try it.

artdeell · 2020-04-05T13:50:24Z

Display list is used in 1.14 to make use unable to exit from the startup process.
Let's hope it will work for 1.11 and older.

artdeell · 2020-04-05T16:27:59Z

LWJGL load only libgl04es.so so if libzinkgl.so or something LWJGL can't find, so need to create 2 different liblwjgl.so

I mean: if end user have a very fast CPU and poor GPU, swrast will be a pretty good solution.

khanhduytran0 · 2020-04-05T23:24:28Z

Looks like I have swrast in this video https://youtu.be/LjcD8rK5ic0
It run on Linux Deploy in framebuffer mode, and have natively OpenGL (and ES) without GL4ES.
It's slow because I install it in slow sdcard, and my CPU is Snapdragom 410, Adreno 306

After that I install using stable GL4ES and XSDL Xserver (unfortunately, 100% lost image) and the tar.gz i provided is unstable GL4ES

Before I noticed something like swrart-dri.so or something not found when trying to run glxgears....

khanhduytran0 · 2020-04-05T23:26:40Z

In this, i have both CPU and GPU poor, but also by slow sdcard.

How to build Regal for Android??
__
I'm finding some issues for something useful.

khanhduytran0 · 2020-04-06T10:41:11Z

So I managed to get Regal built for Android using latest Android NDK in Android Studio.
My Android.mk has some modify to fix some errors so if you clone and put in Android Studio you will get error.

I'm built it by go to regal/build/android/Regal and run ndk-build manually from Terminal.

khanhduytran0 · 2020-04-06T10:44:12Z

If you want binary, get at https://drive.google.com/file/d/1LqjLtptw2hw3y_ghygN9l-0Ucb4RjS1C/view?usp=drivesdk

I didin't build for x86-64 because launcher does not have that ABI and takes more times to compile (for each architecture it takes ~20 minutes to complete build).

You need to modify some parameters of Regal. The parameters and its descriptions are on main Regal README.

artdeell · 2020-04-06T16:43:08Z

glGetString returns something related to OpenGL string statics, like vendor,version , etc...

artdeell · 2020-04-06T16:45:22Z

Can you send me a log? Also, you can try to download AIDA64 and check the Devices and GPU tab (maybe your device is not comparible vith Vulkan?)

gabbosta · 2020-04-06T16:45:53Z

When will launch the new version of Pojav Launcher

artdeell · 2020-04-06T16:46:53Z

Now investigating the issues of Vulkan. Maybe there will be an OpenGL 4 compartiblity!
And after the new pre-release framebuffers, advanced shaders and some high-OpenGL thingies.

artdeell · 2020-04-06T16:49:28Z

@khanhduytran0 did you rebuilded native lwjgl and changed all of the includes to Regal's ones?
Maybe the issue is just because of improper linking.

khanhduytran0 · 2020-04-07T08:18:21Z

i do some quick replace for testing before rebuild everything. seems like Regal need a c++ initialize call.

khanhduytran0 · 2020-04-07T08:20:21Z

anything I will edit to make it work?

Also might need to port displayList from gl4es to Regal.

artdeell · 2020-04-07T08:42:13Z

@khanhduytran0 We need to atleast initialize it correctly

khanhduytran0 · 2020-04-07T10:23:28Z

changed all of the includes to Regal's ones?

https://github.com/p3/regal/blob/master/README.rst

Deployment

Most code remains unchanged.
Optionally #include <GL/Regal.h>
Link with regal32.dll, libRegal.so or libRegal.dylib*

khanhduytran0 · 2020-04-07T11:39:32Z

last commits made 5 years ago

So Regal developer will not have enough time to implement Vulkan.

artdeell · 2020-04-10T05:58:54Z

@khanhduytran0 can you give me your Regal's project directory?
I wanna try to link Regal and Boardwalk's LWJGL 2

khanhduytran0 · 2020-04-10T06:00:03Z

Source code?

artdeell · 2020-04-10T06:01:00Z

In particular, i only need the generated include directory

khanhduytran0 · 2020-04-10T06:06:13Z

https://github.com/p3/regal/tree/master/include (original)

Why generated?

artdeell · 2020-04-10T06:06:42Z

Because generated includes are linked with adresses inside .so file

artdeell · 2020-04-14T05:58:41Z

After change above, I got Minecraft without OpenGL warning!

On Regal library??

khanhduytran0 · 2020-04-14T06:02:55Z

No, still gl4es :(

khanhduytran0 · 2020-04-15T04:56:19Z

Try to FORCE_ES2_CORE_PROFILE and force emulation everything.

khanhduytran0 · 2020-04-15T05:11:50Z

It's blackscreening because Regal needs to share context between libraries

artdeell · 2020-04-16T06:57:23Z

I think we need to stay with GL4ES for the moment, or look for a fork with displayList compartiblity

khanhduytran0 · 2020-04-16T06:59:40Z

How can I disable core ES2 profile when the only thing available on Android is core ES2 profile?

Find a way to disable it by set property or put in Android.mk.

artdeell · 2020-04-16T07:15:37Z

It can't be disabled on Android.

artdeell · 2020-04-16T07:17:47Z

Also Regal doesn't support any kind of display list emulation. That's bad.

khanhduytran0 · 2020-05-09T00:32:30Z

Because Regal is unusable so closing.
