So, I'm testing more. To recap, in SL, it used to be that setting the
metadata of the image to be a 2D texture would automatically put the image
in a mode where it was in GL_REPEAT.
In SL, what was in the last post can be boiled down to:
if([inputGLTEXTURE2D booleanValue])
{
[[inputImage imageValue]setMetadata:[NSNumber numberWithInt:GL_TEXTURE_2D]
forKey:@"textureTarget" shouldForward:YES];
}
[inputImage setOnOpenGLContext: context unit:GL_TEXTURE0];
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_R, GL_REPEAT);
}
To get it working, and have "tiling" repeat effect.
Now, since just making the image 2D to begin with gives the GL_REPEAT
freebie, I've reconfirmed this by testing:
if([inputGLTEXTURE2D booleanValue])
{
[[inputImage imageValue]setMetadata:[NSNumber numberWithInt:GL_TEXTURE_2D]
forKey:@"textureTarget" shouldForward:YES];
}
[inputImage setOnOpenGLContext: context unit:GL_TEXTURE0];
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP);
//glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_R, GL_REPEAT);
}
This, as expected in Snow Leopard, results in a clamped texture.
By this process of elimination, I'm pretty darn sure I'm calling my
parameters in the correct place, and the correct way. This is making me feel
like there has been a regression in the QC Image pipeline that's likely to
effect more patches negatively, but I'm not 100% sure about that of course.
Again, any thoughts or help are greatly appreciated. As is, I think this is
a bug, but since I'm using GFPlugin, I can't really file.
Best,
