Hi osgUsers,
I've been doing some testing on HDR with a backdrop with a .hdr image
using osg::Texture2D for the backdrop works great.. really nice HDR effects.
using osg::TextureCubeMap results with textures loosing values over 1.0
and resulting with a rainbow effect of colors in those areas
in short:
this doesn't work:
osg::TextureCubeMap* texture = new osg::TextureCubeMap;
osg::Image* pImage = osgDB::readImageFile("vinesunset.hdr");
texture->setInternalFormat( GL_RGB16F_ARB );
texture->setResizeNonPowerOfTwoHint(false);
texture->setImage( 0, pImage );
texture->setImage( 1, pImage );
texture->setImage( 2, pImage );
texture->setImage( 3, pImage );
texture->setImage( 4, pImage );
texture->setImage( 5, pImage );
this works:
osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D(
osgDB::readImageFile("vinesunset.hdr") );
texture->setInternalFormat( GL_RGB16F_ARB );
texture->setResizeNonPowerOfTwoHint(false);
texture->setImage( pImage );
can anyone spot what I'm missing?
