[comp.graphics] Graphics card/What features are important?

linde@herds.SRC.Honeywell.COM (Larry G. Linde) (07/03/90)

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?
