Hi all, I want to do RTT with HDR saving only one component (GL_LUMINANCE or GL_INTENSITY) There is my code :
myHDRTexture->setFilter(osg::Texture::MIN_FILTER,osg::Texture::LINEAR); myHDRTexture->setFilter(osg::Texture::MAG_FILTER,osg::Texture::LINEAR); myHDRTexture->setInternalFormat(GL_INTENSITY16F_ARB); myHDRTexture->setSourceFormat(GL_INTENSITY); myHDRTexture->setSourceType(GL_FLOAT); myCameraHDR->setRenderTargetImplementation(osg::CameraNode::FRAME_BUFFER_OBJECT); myCameraHDR->setRenderOrder(osg::CameraNode::PRE_RENDER); myCameraHDR->attach(osg::CameraNode::COLOR_BUFFER,myRenderHDRTexture); when I look values on my texture they are clamped at 1 and if I put : myHDRTexture->setInternalFormat(GL_RGBA16F_ARB); myHDRTexture->setSourceFormat(GL_RBA); my texture contains values upper than 1 Someone have an idea? (I don't need saving three component because they are the same) thanks in advance bnua
