/* Written 9:29 pm May 19, 1989 by jcocon%hazel.cs.@hubcap.clemson.edu in zaphod:comp.sys.mac */ /* ---------- "Drawing In Color" ---------- */ I wrote a program which does raytraces and displays the picture on the screen by directly manipulating the bits of the SE's monochrome screen. Now I would like to show the pictures on a Mac II. Even in monochrome screen the bit manipulations don't work properly, so I moved to quickdraw. Using the moveto and lineto functions, screen drawing now takes minutes rather than seconds. Does anyone out there have info on how to draw in gray tones with quickdraw, then how to do it directly? All of my documentation on quickdraw is pre-Mac II Thanks for the help. Jim /* End of text from zaphod:comp.sys.mac */ We will be soon releasing the source code to NCSA DataScope where I have worked out how to do a "virtual" image buffer. There is also an example disk from APDA with similar code on it. Tim Krauskopf NCSA
