Eight more companies have pledged their support to the Silicon Graphics Inc sponsored OpenGL three dimensional graphics applications programming interface. The companies include new licensees Compaq Computer Corp, 3Dfx Interactive Inc, Rendition Inc, ELSA Gmbh, Number Nine Visual Technologies Inc and InterDimension Multimedia Inc, while Intel Corp and AccelGraphics Inc are upgrading their licenses. Last summer saw Compaq launching its Workstation Division (CI No 2,971), presumably the reason it signed up for OpenGL. OpenGL, now touted as a standard independently of its creator and controlled by the OpenGL Architectural Review Board, has won support from IBM Corp, Digital Equipment Co, Hewlett-Packard Co, Microsoft Corp and Sun Microsystems Inc over the last few years. In all there are now over 50 OpenGL licensees who deliver OpenGL-based products for the personal computer, workstation and supercomputing markets.
