[osg-users] osgText -> fragment shader -> font texture

2010-03-24 Thread Yuriy A Rudomyotov
Hi,

I try to use shaders with osgText to make some effects with text. But how I can 
set up uniform variable with font texture to process it in fragment shader? Or 
may be I should do something another to have result?

Primitive fragment shader:

Code:

uniform sampler2D bitmap;
varying vec2 texelCoord;

void main( void )
{
gl_FragColor = vec4( texture2D( bitmap, texelCoord ) );
}




Code which sets the variable:

Code:

//...
osg::Uniform* bitmap = new osg::Uniform("bitmap", osg::Uniform::SAMPLER_2D);

bitmap->set(??);

text->getOrCreateStateSet()->addUniform(bitmap);
//...




Thank you!
