[osg-users] 32bit DEPTH for RTT

[Voerman, L.]

Hi Trajce,
maybe this sniplet helps?
_textureDepthBuffer = new osg::Texture2D;
_textureDepthBuffer->setTextureSize(_width+2.0f*_width*_guardBandPercentage,
_height+2.0f*_height*_guardBandPercentage);
_textureDepthBuffer->setSourceFormat(GL_DEPTH_COMPONENT);
_textureDepthBuffer->setInternalFormat(GL_DEPTH_COMPONENT32);
_textureDepthBuffer->setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::NEAREST);
_textureDepthBuffer->setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::NEAREST);
_textureDepthBuffer->setShadowComparison(false);
_textureDepthBuffer->setWrap(osg::Texture::WRAP_R,osg::Texture::CLAMP_TO_EDGE);
_textureDepthBuffer->setWrap(osg::Texture::WRAP_S,osg::Texture::CLAMP_TO_EDGE);

// camera
_colorDepthCamera = new osg::Camera;
_colorDepthCamera->setStats(new osg::Stats("Camera"));
_colorDepthCamera->setName("colorDepth");
_colorDepthCamera->setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
_colorDepthCamera->setReferenceFrame(osg::Transform::RELATIVE_RF);
// set viewport
_colorDepthCamera->setViewport(0,0,_width+2.0f*_width*_guardBandPercentage,_height+2.0f*_height*_guardBandPercentage);
_colorDepthCamera->setRenderOrder(osg::Camera::PRE_RENDER,0);
_colorDepthCamera->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
_colorDepthCamera->attach(osg::Camera::DEPTH_BUFFER,
_textureDepthBuffer.get(),0,0,false,0,0); // depth
_colorDepthCamera->attach(osg::Camera::COLOR_BUFFER,
_textureColorBuffer.get(),0,0,false,_msaa,_msaa); // color
regards, Laurens.
