Direct3D meant for 3D hardware interface. The feature set of D3D is derived from the feature set of what hardware provides. OpenGL meant to be a 3D rendering system that may be hardware accelerated. There are functional differences in how the two APIs work. Direct3D expects the application to manage hardware resources; OpenGL makes the implementation do it. This makes it much easier for the user in terms of writing a valid application, but it leaves the user more susceptible to implementation bugs that the user may be unable to fix. At the same time, because OpenGL hides hardware details, the user is unable to query the status of various hardware resources. The Direct3D model frustrated many programmers. I do remember a game developer named John Carmack who urged Microsoft to abandon Direct3D in favor of OpenGL! > Robert Hancock Saskatoon, SK, Canada ~Akula2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
