[osg-users] osgText and OpenGL ES 3

[Sebastian Messerschmidt]

Hi,

Resending the attachment for forum users as zip.

> Hello,
>
> I am trying to port my project using OSG 3.4.0 on iOS.
> I first tried to modify OSG sources to be fully usable with an OpenGL ES 3 context, as other dependencies require OpenGL ES 3.
>
> I managed to run osg on my iPad, modifying shaders and removing duplicates while merging them, but osgText is making me crazy |-)
> I tried to debug using only the osgtext.cpp example.
>
> I embedded a font with my application in a bundle, and successfully load it. I modified osgText/Glyph to use GL_RED as glyph texture format.
> Only the DefaultFont is correctly rendered. Other Glyphs are not rendered, only their bouding boxes (cf. attached image).
>
> Does anyone has an idea on what could be the cause?

> Cheers,
