During the changes made years ago to MiniGL version 2.21 I remember that we had encountered some bugs in PrBoom Plus (HunoPPC version)
Some were obviously fixed but it seems we still have a couple of more bugs left that lead in certain graphical glitch

See grab: https://imgur.com/iENdl3e

In the grab you can see:

1) In certain levels of the game we can noticed some small colored dots (white or red) into the floor's texture

2) In GL mode the enemy bodies are displayed incorrectly in respect to the floor

If needed this is the PrBoom Plus's output:

wrt to that "seam" visible, i hvae something similar.

Did you ever seens something like this?
What could it be affected by?
Resized Image
Full picture is here

@Bszili thinks it might be a texture clamping issue.

Could this be in some other way than residualvm confirmed and probably fixed?

Thanks a lot

A clamping issue could indeed cause those seams, or some slight differences in vertex coordinates. That's more likely the culprit than a shader compiler bug, especially for a simple skybox.

EDIT: Texture clamping issues are an app/game bug. You need to change the texture's edge clamping rules. Try changing the texture's GL_TEXTURE_WRAP_S/T modes to GL_MIRRORED_REPEAT.

I just wonder why it works on every other platform they support...and there are many...

Does it? You made it sound like the ResidualVM team may have confirmed and fixed it:

Have you tried the suggested fix?

@Raziel
Huh?! Isn't that the MiniGL thread? AFAIK MiniGL (and Warp3D) only support GL_REPEAT and, well, "something else" That "something else" (there is no parameter check in MGL here...) always maps to W3D_CLAMP (as would GL_MIRRORED_REPEAT...).

Now, I can only speek for the R200 driver, but here W3D_CLAMP maps to the function "clamp to last texel", which is what you usually want and which coresponds to GL_CLAMP_TO_EDGE (not GL_CLAMP!). This definitely cannot produce such artefacts as you see here.

@Raziel
What card / driver are you running your test on? To me it looks as if it would falsely switch to a wrap function like GL_CLAMP_TO_BORDER or GL_CLAMP asuming a texture with a single colored border.
You could try searching the code for everything that starts with GL_CLAMP temporarily replace it by GL_REPEAT to see if that changes something.

Or maybe it's a numeric issue and the cube's coordinates are just a tiny tiny bit off so that what you see as lines is actually the background color shining through. Try locating the glClear command in the code and temporarily put a glClearColor(1,0,0,1) in front of it. If the lines become red, then this is the problem.

EDIT: after zooming into the picture I don't think its the numeric issue.

Nope, bad english, let me rephrase that:

Could this be confirmed/checked in some other way/app/code example than residualvm, and then be fixed (in residualvm too)?

@Daniel

kas1e sent me here from the ogles2 thread, so i thought it might be the rught place...it obviously isn't

RadeonHD 7750
RadeonHD.chip 2.10 (03.05.2015)

I will try your suggestions, thank you

@Daytona675x

I've found something in the specific code, two instances with remarks...

gfx_opengl_texture.cpp
// TODO: If non power of two textures are unavailable this clamping
    // has no effect on the padded sides (resulting in white lines on the edges)
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_WRAP_SGL_CLAMP_TO_EDGE);
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_WRAP_TGL_CLAMP_TO_EDGE);


gfx_tinygl_texture.cpp
// NOTE: TinyGL doesn't have issues with white lines so doesn't need use TGL_CLAMP_TO_EDGE
    
tglTexParameteri(TGL_TEXTURE_2DTGL_TEXTURE_WRAP_STGL_REPEAT);
    
tglTexParameteri(TGL_TEXTURE_2DTGL_TEXTURE_WRAP_TTGL_REPEAT);

No no, it may well be the right place, if you are using MiniGL under the hood and not e.g. gl4es or ogles2 directly.
Are you using MiniGL? For now I asume you do (therefore you can also ignore the gfx_tinygl_texture.cpp )

Anyway, as I said in my previous post: On MiniGL GL_CLAMP_TO_EDGE maps to W3D_CLAMP and on R200 this maps to "clamp to last texel" which is what you'd expect and which doesn't produce such artefacts. The question is what your RadeonHD driver makes out of it. Therefore just try out what happens if you use GL_REPEAT (and nothing else!) instead of GL_CLAMP_TO_EDGE.
If that doesn't get rid of your black lines then it's not wrap-mode.

Btw.: those "white lines" comments make no sense to me.

@Hans
wasn't there a similar issue once in Warp3D Nova and the Q3 mirrors?

wrt to "white lines"
Maybe they got those visible borders in white instead of black while developing?

I changed GL_CLAMP_TO_EDGE to GL_REPEAT but there is no change whatsoever, the borders persist. (I also tried with GL_MIRRORED_REPEAT, like Hans was suggesting, but that didn't help either)

Then revert to GL_CLAMP_TO_EDGE and instead try the following please:
search the code for GL_TEXTURE_MIN_FILTER and change any eventual ...MIPMAP... value (the respective commands last parameter) to GL_LINEAR, e.g. glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

The reason is that IIRC W3D Nova had some issue with mipmapping and such artefacts in Q3 under certain circumstances, maybe the "normal" Warp3D driver on your RadeonHD suffer from sth. similar.

As being said this made no sense anyway as it would behave exactly like everything else not being GL_REPEAT on MiniGL.

I can only find one line and that is already exactly like you posted
Quote:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);


Here is the whole part of the code
OpenGLTexture::OpenGLTexture(const Graphics::Surface *surface) {
    
width surface->w;
    
height surface->h;
    
format surface->format;

    
// Pad the textures if non power of two support is unavailable
    
if (OpenGLContext.NPOTSupported) {
        
internalHeight height;
        
internalWidth width;
    } else {
        
internalHeight upperPowerOfTwo(height);
        
internalWidth upperPowerOfTwo(width);
    }

    if (
format.bytesPerPixel == 4) {
        
assert(surface->format == getRGBAPixelFormat());

        
internalFormat GL_RGBA;
        
sourceFormat GL_UNSIGNED_BYTE;
    } else if (
format.bytesPerPixel == 2) {
        
internalFormat GL_RGB;
        
sourceFormat GL_UNSIGNED_SHORT_5_6_5;
    } else
        
error("Unknown pixel format");

    
glGenTextures(1, &id);
    
glBindTexture(GL_TEXTURE_2Did);
    
glTexImage2D(GL_TEXTURE_2D0internalFormatinternalWidthinternalHeight0internalFormatsourceFormat0);
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_MIN_FILTERGL_LINEAR);
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_MAG_FILTERGL_LINEAR);

    
// TODO: If non power of two textures are unavailable this clamping
    // has no effect on the padded sides (resulting in white lines on the edges)
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_WRAP_SGL_CLAMP_TO_EDGE);
    
glTexParameteri(GL_TEXTURE_2DGL_TEXTURE_WRAP_TGL_CLAMP_TO_EDGE);
    
    
update(surface);

}


That "non power of two" comments are regarding to not available ARB shaders, i believe?
Because i get this on start of the game:
Quote:

Initializing OpenGL Renderer
WARNING: GL_ARB_texture_non_power_of_two is not available.!

Then the most likely culprit now becomes the game itself.
It obviously contains code somewhere for upscaling non-power-of-two-textures, because it uses a texture-size upscaled to the next power of two if NPOT textures are not supported. Are the sky-cube textures NPOT?

NPOT = Non-Power-Of-Two
What are the pixel sizes of the textures used in your screenshot ? Can you open the texture files in your favorite paint-program and tell me?
If they are not a power-of-two then the game will apparently scale them to the next higher power-of-two. And that (unknown) code may be buggy.

No idea, really, sorry.

I can't open the data files as they are packed together which no paint program (i have) can handle. They are called xxxnodes.m3a and such.

Then please get me all the source code for that class OpenGLTexture instead please, I suppose the coresponding code is inside that.

I think Daytona675x is on to something.

The Non-Power-Of-Two (NPOT) warning may well be why it looks okay on other OSes, and not on AmigaOS with MiniGL. The hardware handles NPOT on the other OSes, whereas with MiniGL the game/app needs to convert those textures to have a width and height that is a power-of-two. If they simply pad the texture with white/black/whatever, then that border can leak through as seams.

Answering some of your queries/comments:
1. The RadeonHD Warp3D driver correctly handles all of the texture wrap modes
2. The triangle edges that were visible in Q3 via GL4ES look different, and were due to the shader compiler not generating "exit whole-quad-mode" code for all cases when it's necessary. I went through, and added that everywhere where it was needed. While it's always possible I missed one, it's very unlikely to be triggered by a simple skybox render
3. The Warp3D driver already has the "exit whole-quad-mode" code, which is called whenever textures are used
