Hi, We (as in a small startup) are looking for ideas as to what is required for a excellent graphics product. IE: What features are important. In addition to trying to start some discussion on the topic of the upcoming revolution in High Performance graphics systems. First some baseline information, Platform: Sun SPARCstation (SBUS Interface card) Size: Single card same footprint as SPACRstation box. Speed: 350K 4 sided polygons (unconnected) (3sided same speed) polygon strips same speed (100 pixels area average) Features: Full Texturing Torrance-Sparrow model lighting Can degrade into Phong model lighting Can degrade further into gouraud shading Can degrade further still into constant shading (no speed penalities for any lighting/shading/texturing model.) Double buffered on image display Fast 2D access to display memory 24 bits (RGB) 8 bits Alpha, 24 Bits Z SW support: SUNPhigs, PEX as soon as its somewhat stable. (3/91?) X11R4 Device support. Our questions are: 1: Is PEX going to be the next standard? How about Renderman? 2: What features are important on high end graphics systems? 3: What price do you think such a device is worth?
