Glossary Of 3-D Terms
DirectX: This set of libraries based on component object model (COM) includes DirectDraw, DirectSound, DirectInput and DirectPlay components. Microsoft added Direct3D to DirectX 2.
-- DirectDraw allows direct manipulation of display memory, hardware blitters (circuits used for transferring large volumes of graphic information), hardware overlays and flipping.
-- DirectInput provides joystick, keyboard and mouse support.
-- DirectPlay lets applications communicate independent of the underlying transport, protocol or online service.
-- DirectSound provides low-latency mixing, hardware acceleration and direct access to the sound device.
-- Direct3D is a set of real-time 3-D graphics services that delivers fast software-based rendering of the full 3-D pipeline and transparent access to hardware acceleration.
OpenGL: This industry-standard programming interface makes it easier for apps to draw 3-D graphics.
Scenegraphs: These are descriptions contained in VRML files of the objects, lighting and cameras needed for constructing a self-contained 3-D "world."
Virtual Reality Modeling Language (VRML): VRML is a compact, cross-platform 3-D description standard for handling 3-D over the Web.
