&gt; Subject: [MUD-Dev] How to represent a 3d object...
&gt;
&gt;
&gt;
&gt; I am thinking about how to represent a 3d object in a 3d world.
&gt;
&gt; I believe that polygon rendering is my best bet, both because
&gt; I am not horribly efficient with graphics programming, and because
&gt; it is easy for me to realize.  Also, the new Java 2d API should
&gt; give the the support I need....
&gt;
&gt; Still, I'll need to be able to figure out what polygons to draw,
&gt; and what to fill (tile) them with....
&gt;
&gt; I envision the object as a collections of intersections (nodes)
&gt; and faces.  To draw the object, then I'll calculate orientation
&gt; and distance from the viewer, figure out what sides (faces) are
&gt; visible, and then draw each face onto a 'canvas'.
&gt;
&gt; The two big questions are:  what kind of data structure should I
&gt; use for in-memory storage, and how to encode this for storage in a
&gt; persistant storage mechanism.  I can see advantages of allowing only
&gt; three vertices to protrude from any given node, but perhaps other
&gt; systems are better?
&gt;
&gt; There must be some standard way of representing this on disk,
&gt; does anyone have any pointers??
&gt;
&gt; Thanks,
&gt; Ben
