We are having problems at our site with Sun Graphic Cards. It seems that Sun does not sell a graphics card like we need. We are working on several different projects and we want to work on any project at any station, not only graphics on one and lisp on another. In addition to this, we had a GXP that runs well, but which does not support the new standards like Open Windows. That is part of the problem. Which card do we really need, and what can we do in the future with the hardware that Sun will not support ? I know some of the characteristics of the current Sun cards: GX GXP CXP ==================================================================== cards CG6 CG9+GP2 CG5+GP2 LISP yes NO !! yes CORE NO NO yes PHIGS, GKS yes yes yes OPEN WINDOWS yes NO NO HARD DOUBLE BUFFER NO NO yes vect/s 2D 400K -- 200K vect/s 3D 175K 90K 150K pol/s (gouraud) 40K 5'5K 20K The problem is, we are using CORE, although we could change to PHIGS, and we use lisp, we want speed in graphics, and we would like to use X11. Obviously there is not a Sun card that can support all of this things. I have asked SUN's technical support (hotline@sun.com) but they have not given their response. The best solution seems to be to change to the GX card and change our programs from core to phigs, but GX is only one card, does not have a double buffer, and it's cheaper than the others. Can it really be faster? Could you tell me if SUN is thinking of making a patch for GXP to support lisp or X11, or a patch for GXP, or of making a new, faster GX with or without core, and if a GX without double buffer hardware really runs faster with dynamic graphics, such as with images of robots in real time. I would appreciate your answer. Please send answers directly to me. Emili Sanrom`. Institut de Cibernhtica. Barcelona. Espanya. sanroma@ic.upc.es (ean) sanroma%ciber@ic.upc.es sanroma@EBRUPC51.BITNET
