Hi Remo,
A more detailed description on how it fails would be helpful.
If you're seeing non-textures quads instead of your glyphs you need to
adapt your shader as the text-rendering isn't using a normal blending.
I've attached my default core-profile shader which uses pre-multiplied
alpha.
Additionally I add a default sampler at camera root for the osg_Texture
and I do:
for (auto index = 0u; index < mMainViewer->getNumViews(); ++index )
{
getCamera(index)->getGraphicsContext()->getState()->setUseModelViewAndProjectionUniforms(true);
getCamera(index)->getGraphicsContext()->getState()->setUseVertexAttributeAliasing(true);
}
nsRenderer::Helpers::addTexture(
stats_handler->getCamera()->getOrCreateStateSet(), "osg_Texture",new
osg::Texture2D(nsRenderer::Helpers::getDefaultImage(false)), 0);
Hope that helps
Sebastian
Hi,
I can't render osgText on MacOSX Core Profile:
text->setTextBackdropType(osgText::Text::BackdropType::NONE);
text->setTextBackdropImplementation(osgText::Text::BackdropImplementation::DELAYED_DEPTH_WRITES);
text->setBackColor( Color( Color::Black, 0.8 ) );
text->setHorizAlign( Control::ALIGN_RIGHT );
text->setVertAlign( Control::ALIGN_BOTTOM );
text->setVisible( true );
I've also tried to apply a default shader. But it doesn't work at all.
Cheers,
Remo
