Hi,
I'm looking to modify the amount of reflections intensity inside ocean. I'm
using last trunk rev 258.
I'm stuck into this piece of code inside OceanScene:
Code:
_reflectionMatrix = osg::Matrixf( 1, 0, 0, 0,
0, 1, 0, 0,
0, 0, -1, 0,
0, 0, 2 *
_oceanScene->getOceanSurfaceHeight(), 1 );
osg::ref_ptr<osg::Texture2D> reflectionTexture =
_oceanScene->createTexture2D( _oceanScene->_reflectionTexSize, GL_RGBA );
// clip everything below water line
_reflectionCamera = _oceanScene->renderToTexturePass(
reflectionTexture.get() );
_reflectionCamera->setClearColor( osg::Vec4( 0.0, 0.0, 0.0, 0.0 ) );
_reflectionCamera->setComputeNearFarMode(
osg::Camera::DO_NOT_COMPUTE_NEAR_FAR );
_reflectionCamera->setCullMask( _oceanScene->_reflectionSceneMask );
_reflectionCamera->setCullCallback( new
CameraCullCallback(_oceanScene.get()) );
_reflectionCamera->getOrCreateStateSet()->setMode( GL_CLIP_PLANE0+0,
osg::StateAttribute::ON );
_reflectionCamera->getOrCreateStateSet()->setMode( GL_CULL_FACE,
osg::StateAttribute::OFF | osg::StateAttribute::OVERRIDE );
_surfaceStateSet->setTextureAttributeAndModes(
_oceanScene->_reflectionUnit, reflectionTexture.get(), osg::StateAttribute::ON
);
I think that I should operate on texture properties, maybe the shader but right
now I'm not able to see a significative change on intensity reflection
effect...Someone can suggest to me a way?
Thank you!
Cheers,
Dario[/code]
