In computing, the Direct Rendering Infrastructure (DRI) is an interface and a free software implementation used in the X Window System to securely allow user applications to access the video hardware without requiring data to be passed through the X server. Its primary application is to provide hardware acceleration for the Mesa implementation of OpenGL. Without DRI, programs have to use the CPU while rendering (indirect rendering), which degrades overall performance. DRI has also been adapted to provide OpenGL acceleration on a framebuffer console without an X Server running.

Famous quotes containing the words direct and/or rendering:
“One merit in Carlyle, let the subject be what it may, is the freedom of prospect he allows, the entire absence of cant and dogma. He removes many cartloads of rubbish, and leaves open a broad highway. His writings are all unfenced on the side of the future and the possible. Though he does but inadvertently direct our eyes to the open heavens, nevertheless he lets us wander broadly underneath, and shows them to us reflected in innumerable pools and lakes.”
—Henry David Thoreau (1817–1862)
“By rendering the labor of one, the property of the other, they cherish pride, luxury, and vanity on one side; on the other, vice and servility, or hatred and revolt.”
—James Madison (1751–1836)
