1818.0. "Surf's up!" by ROMULN::MYEE (Boycott Styrofoam cups, save the ozone.) Wed Oct 26 1988 16:20

    Surf is now available on ROMULN::DUB3:[PUBLIC.AMIGA]SURF.ZOO.
    Haven't tried this SW out, but looks like it could be interesting.

Description
-----------
BezSurf (or Surf for short) is a program for producing bezier surfaces of
revolution. It produces awesome pictures of wineglasses and doorknobs, and
other objects one could turn on a lathe. BezSurf includes the capacity to
map iff image files onto any surface that it can draw.

1818.1he who hesitates...LEDS::ACCIARDIDukakis should pluck his eyebrowsWed Oct 26 1988 16:2514
    
    Damn, you beat me to it Mike.  I was going to upload this one tonight.
    
    Surf is a nice little way to experiment with polygon rendering without
    springing for a full blown ray tracing system like Sculpt or Turbo
    Silver.
    
    It has a nice user interface and runs very quickly.  Give it a try.

1818.2saved files/interior viewMIST::TBAKERTom Baker - DECwest CSSEFri Oct 28 1988 21:0714
    Surf is an interesting program. I'm having one problem. I can save
    a picture to disk as x.ilbm but I can't get it back into surf.
    Open Map asks for input file but then nothing happens. Isn't this
    possible or am I doing something wrong?
    
    It's fun to watch the wireframe or the shaded solid object being
    drawn. You can see the internal structure being formed. But when
    the drawing is complete, only the exterior is visable. Is it possible
    to stop the drawing before the shell is complete and you can still
    see the inside?
    
    thanks,

1818.3True meaning of Map commandNAC::PLOUFFCider Season Has BegunFri Oct 28 1988 22:1021
    The map file is the ILBM file which will be projected onto the solid
    you're currently drawing.  The procedure goes something like:
    
    	0.  From the control panel menu, turn dithering OFF.
    	1.  Draw some neat shape with a light background (nearly white).
    	2.  Save it as picture1.ilbm.
    	3.  Draw a simple shape which occupies most of the screen. 
    	    Use illumination > 1 and Kdiffuse nearly 1.  This will
	    give you a picture with a lot of saturated white.
    	4.  Open map file picture1.ilbm from the control panel menu.
    	5.  Set repetition count sliders at bottom of the control panel
	    to, say 12 vertical and horizontal.  (Sorry, forgot name).
    	6.  Go to rendering screen and click on MAP.
    	7.  Come back in an hour and see the first picture wallpapered
	    to the second.  Save this as pic1pic2.ilbm.
    
    There appears to be no way to read a picture back in to Surf for
    further manipulation.  The above was learned by trial and error
    in several midnight sessions.
