I'm trying to construct some space scenery containing a few very large
objects (Sun, Earth, Moon), and a small number of space vessels (~200 m in
length). I started out using a scale of 1 unit = 1 m, but found that large
objects in the scene disappeared - they simply weren't being rendered. I
switched to 1 unit = 1e6 m, which I thought might be a good compromise,
which is better, but the image is very grainy when both large and small
objects are rendered in the same scene. I think these effects must be due
to limits of floating-point precision (this is POV-Ray 3.6 on 32-bit
Windows XP). Is there any kind of workaround for this? I'd really like to
work to scale if possible.
Is the 64-bit version of POV-Ray likely to work better for this kind of
scenery? I am using an AMD64 system but currently have no 64-bit Windows
installation; IIRC, SSE/SSE2 has 128-bit FP registers.
Thanks in advance!
