Hi, I've been banging my head against how to save a 3D texture out to a dds file for some time now. I've read posts that suggest simply attaching the texture's image to the buffer rather than the texture itself. I've done that for 2D textures with no problem. However, I don't see how that will work in this case; given the setup below.
Code: ... camera->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT); camera->setImplicitBufferAttachmentMask(osg::Camera::IMPLICIT_COLOR_BUFFER_ATTACHMENT, osg::Camera::IMPLICIT_COLOR_BUFFER_ATTACHMENT ); camera->attach(osg::Camera::COLOR_BUFFER0, tex1, 0, osg::Camera::FACE_CONTROLLED_BY_GEOMETRY_SHADER); camera->attach(osg::Camera::COLOR_BUFFER1, tex2, 0, osg::Camera::FACE_CONTROLLED_BY_GEOMETRY_SHADER); viewer.frame(); ... So, after I render the frame I want to be able to say Code: osgDB::writeImageFile( *tex1->getImage(), "foo.dds" ) But, of course, this doesn't work since the image isn't updated when the texture changes. Is there a strait forward way to get the texture data back to an image that I'm missing? Thank you!
