8. OpenGL SC Emulation Based on OpenGL and OpenGL ES 131
on an Intel Core2 Duo–based system with 4GB of RAM and NVIDIA GeForce
8600 graphics card. Figure 8.9 shows some screenshots from the test programs.
8.5 Conclusion
According to our tests, all the core and extension features of OpenGL SC can be
achieved as an emulation layer over OpenGL 1.1 hardware equipped with the multi-
texture extension. The results demonstrate the effectiveness of our approach. Our
implementation is able to run various OpenGL SC applications and conformance
tests correctly with less than 2% performance overhead. Our next step is to imple-
ment OpenGL SC over lower-powered
