  22.  
  23. Wrong. I see you dont know anything about Amiga hardware programming.
  24. But you shoot sentences about it.
  25.  
  26. > Both are different operations and you can even do both through the OS.
  27.  
  28. Do you think the same thing will be fast with a SVGA card and only 8bit chunky
  29. modes? It'll be damn slow. At this point, I dont care if it's compatible.
  30. It's useless.
  31.  
  32. >>Similarly, we could use a 3d.library (for vector graphics), chunky.library
  33. >>(for chunky operations), etc.etc. If these were written using the most
  34. >>optimal techniques possible, and supported and updated, they could solve a
  35. >>lot of the Amigas problems..
  36.  
  37. >Well, even a 3d.library or chunky.library had to be based on graphics
  38. >operations. Nothing prevents you from writing your own 3d routines and
  39. >use graphics for the display.
  40.  
  41. Using WritePixel() of course.
