Hi,
i am trying to get RGB value(los point) of Terrain
i tried with below code.
osg::Drawable * drawable = intersection.drawable.get();

{
state_set = drawable-getStateSet();
osg::Texture * texture = state_set-getTextureAttribute
(0, osg::StateAttribute::TEXTURE)-asTexture();
if(texture-getImage(osg::Material::FRONT))
printf(%f %f
%f\n,texture-getImage(osg::Material::FRONTFACE)-getColor(intersection.localIntersectionPoint).r()
,texture-getImage(osg::Material::FRONTFACE)-getColor(intersection.localIntersectionPoint).g()
,texture-getImage(osg::Material::FRONTFACE)-getColor(intersection.localIntersectionPoint).b());
}
///
But i only got RGB value as (1,1,1)
Could u let me know why the value is always (1,1,1)
Thank you in advance for any help
Cheers,
Kim

Hi, guys i would like to learn differences between osgParticle (particle system) and osgParticle::PrecipitationEffect. i tried to implement snow/rain effect with them but the result is totally different so why is that? especially, osgParticle (particle system)'s performance is very low even if i render little particles with short life span and at the small part. on the other hand, PrecipitationEffect render at the whole scene but performance is high(frame rates) so could you explain that the differences and how they work i mean the principles plz~ Thank you so much guys !
