Field vs. Frame
Larry, the field rendering in 3DS has nothing to do with recording the finished
frame to a VTR. It's obvious some of you have never tried this field rendering
process. I'm surprised at all this confusion and over complication of such a
simple process. If you would just try it you would see that the sequence of
events is that after all materials etc are loaded 3DS goes into render mode.
See the red bar go left to right? OK, now see the red bar go a second time
left to right. That's right! it is now doing the second field which is being
interlaced. Next, depending on what you have set up the frame is either
recorded to video and /or stored to HDisk. The recorder is not activated until
both the even and the odd lines have formed the complete frame. You can watch
all this sequence of events on your monitor and see that the frame is not
recorded until 3DS is done rendering twice. Since materials etc are loaded
once for both fields the process of field rendering is not quite twice as long
as with frame rendering on a single frame render. I only use field rendering
when there is alot of high speed movement. It definitly is smoother.
