Shading and classification are among the most powerful and important techniques used in volume rendering. Unfortunately, for hardware accelerated volume rendering based on OpenGL, direct classification was previously only supported on SGI platforms and shading could only be approximated inaccurately, resulting in artifacts mostly visible in darkening. In this paper, we present...
