The OpenGL ES 2.0 thread

Thank you Daniel
Thank you kas1e
Thank you Capehill
Thank you afxgroup

I really like to read Daniel's detailed release notes, compared to those that ship with PlayStation 4 firmware updates "This system software update improves system performance" :)

@Capehill
Yeah, Daniel's changelog is how any changelog should looks like. I also love the DOS's changelogs from Colin on dos.library, they also quite well written too.

Quote:

I asked Hans to add this missing instruction as it block os from gl2 version of q3 with shaders, so maybe he will find some time for ..

@Capehill
You may want to add to the list those ones as well:

http://os4depot.net/share/game/misc/scummvm.lha (this one use ogles2 directly now)

Then MaceDefence game from Entwickler-X (also use ogles2)

https://entwicklerx.itch.io/mace-tower-defense


and Jedi games:

http://os4depot.net/index.php?functio ... me/fps/openjk_academy.lha
http://os4depot.net/index.php?functio ... me/fps/openjk_outcast.lha

They are gl4es based (so ogles2 as well in end).

And the latest public ogles2 now is ogles2.library 3.3 (30.4.2022)

@kas1e

Updated.

@Capehill
You can add at first post those ones as well:

http://os4depot.net/share/game/action/billyfrontier.lha
http://os4depot.net/share/game/adventure/ottomatic.lha
http://os4depot.net/share/game/driving/cromagrally.lha
http://os4depot.net/share/game/board/dungeonofchess.lha

@kas1e

Added.

I wish OS4Depot had some kind of tagging/keyword system. For example, if you search for "ogles2", there is about 2 hits currently.

@Capehill

hello, you also have these games there which are passed on opengles, thank you.

Added to the list.

does OpenGL ES 2.0 have OpenGL Mathematics? (this is the glm library I mean,) not the usual stuff that OpenGL itself has. If I understood Khronos, the glm library is important for shaders.

@trgswe

GLM is an independent library that anyone can get from here. It's *not* part of OpenGL, nor is it essential. You can create your own OpenGL compatible mathematics classes/libraries, or use one of the many existing ones. For example, most of the Warp3D Nova examples use kazmath, while the W3DNLogo example uses my own matrix and vector classes. I could just as easily have used GLM.

Hans

maybe it is my fault but can't find any infos about OGLES and Warp3DNova hw requirements.
Could someone pls enlighten me? :(

@Reynolds
OGLES2 will work on any hardware where you have working Warp3DNova. And Warp3DNova works on most of HD and RX cards, there is more info:

(see the Requirements part)

@all

I've got a slight problem with ScummVM and it seems to boil down to our ogles2 (not sure though)
I'd like to ask anyone with access to the latest ogles2 beta stuff to do a quick test and maybe (if error is confirmed) alert the maintainers to take a look.

That would be awesome.

Here goes:

Download needed files from here

1 - Download and unpack ScummVM
2 - Download and unpack "The 13th Disciple" (it's freeware)
3 - Start ScummVM
4 - Add the game to ScummVM
5 - Go to "Global Options/Graphics"
6 - Change "Graphics Mode" to "OpenGL"
7 - Leave the "Scaler" be, but change it's "Size" to "1x"
8 - Start "The 13th Disciple"

The cursor should come up as a black rectangle instead of the hardware one.

A little information:
Most of the games supported in ScummVM use their own cursor sprite provided by the game's data, some don't.
In these cases ScummVM reverts to use the hardware sprite provided by the system/platform.

This seems to be broken in our (i guess) ogles2 implementation (or rather it seems to read from the wrong memory addess or a random one, since some games display pixel mush, instead of a black rectangle, depends on how many games have been started and quit).

The problem is, that i don't know from where exactly this glitch is coming from or rather which part is reading the wrong address.
It may even be SDL2, so i need someone with access to the ogles2 beta stuff to run the test and report back, please.

Thank you very much in advance

@Raziel

Which OpenGLES 2.0 version?

@Capehill

The last officially available

@Raziel

Okay, but did you receive beta version from Daniel earlier this year?

@Capehill

I did actually and i tested it, but it had a major flaw in which the app screen was shrinked to the size and position of the mouse pointer, after the first click of the mouse pointer anywhere in the app screen. I could even move around that tiny window by moving around the mouse (and see that the game list changed when I "clicked" in it).

I reported it back immediately to Daniel, but never got an answer.

It was unusable, so i dropped testing any further.

I wrote to him again yesterday...until now, no answer

@Raziel

Ok. I can say there was some FBO-related change that fixed ScummVM "first frame glitch" at least.

I hope we get a public update soon.
