[osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

[Remo Eichenberger]

Hi Sebastian

I'm wondering if you have a running osgText on MacOSX Core Profile. Your shader-code is not compatible with it. I've written a partial working version of this shader. I also found that the Glyph Texture is created with red. But i think something is wrong with the texturecoordinates. I don't see any glyph.


Code:
uniform sampler2D glyphTexture;
in vec2 texCoord;
out vec4 color;
void main()
{
  color = vertexColor * texture(glyphTexture, texCoord).r;
}




I'm not sure the code of "Text::drawForegroundText" can work with VAO (It's required on MacOSX)

Here you find a draw dump from MacOSX:
