Bob:
There is a bug fix in 1.2.1 beta that was omitted in the README
that could fix your problem:
4345505 - Multiple transparent objects do not render correctly
I verified that 1.2 FCS behaves incorrectly for this case, but this case
works on 1.2.1 beta.
For the second part of your question:
>>I also did not see listed the quaternion problem I mentioned a while ago.
>>Quat4d(v.x, v.y, v.z, 0.0); results in a normalized quaternion regardless
of
>>the values for v.x, v.y, v.z. This also happens with Quat4f.
>>
>>The only quaternion bug listed was
>>4303052 Quaternion documentation is inadequate
The constructors and set methods of the quaternions always normalize
the quaternion. This needs to be documented (bug 4303052 should be
updated to reflect this). Providing an unnormalized quaternion would
be an API change. We don't currently plan on doing this, but we could
add it to the list of potential 1.3 features if there is enough
interest.
