Then the setup code would look like (pseudo code):
eglBindAPI(EGL_GALLIUM_API_MESA); ctx = eglCreateContext(); suf = eglCreateWindowSurface(); eglMakeCurrent(ctx, surf); And the new "Gallium Client API" provides: p_context = g3dGetContext(); fb = g3dGetFramebuffer(); This way, it allows mixing OpenGL/OpenVG/Gallium, and resource sharing between them. -- Regards, olv ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
