Polygons arise when an object's surface is modeled, vertices are selected, and the object is rendered in a wire frame model. This is quicker to display than a shaded model; thus the polygons are a stage in computer animation. The polygon count refers to the number of polygons being rendered per frame.

To take the most advantage of a scene, you'd want a low poly count if you were going to place many objects inside of the scene with your character. The polys in the scene dictates the render time (not to mention the size of the textures also contribute to the rendering time). Understandably, the more polys you have, the longer it takes to render. The same with very large textures. Of course, most prefer larger texture maps because they provide a better level of detail.

DAZ|Studios is to me the greatest software there is. Although the later releases of the software are supposed to be easier to use (and offers a level of modeling), I rely on an older version just because it's what I know and is more user friendly to me.

I hope this helps. =)
