[Top10-devel] Software rendering ...

[Lars Segerlund]

 I'm giving my renderer a massage :-) .. to se if it will be possible 
to still get resonable performance with top10 running ..

 What I have done so far is a quick fix to render from position x,y 
.... and not to use any height .. this enables me to use a cheat to 
render the ground .. I only render a 'truncated pie' segment :

+--------------+
 \            /
  \          /          Seen from above ...
   \        /
    \      /
     +----+

       +     <- point of eye ....

  The trick is to use the highest point of the line closest to one self 
as reference of the height to render .. ( in other words, my own 
viewpoint ..

  Of the plane that is the ground .. this does not make it a 'flat' 
ground, but the first code to test with top10 will probably be 'flat'.

  It should giva some indication if this is a workable solution as the 
graphics transformations are basicly nonexistent :-) , so it could give 
GOOD speed for small systems.

  I think it would be nicer to get something running than to spend to 
much time trying to get the bells and whistles in there.

  So if I get it running a simple proof of concept should ge usable in 
a  week or two ...
