Re: [geomview-users] Geomview

Hi,

Fedora 4 extras now have geomview 1.8.2 RPM which however
presents itself as 1.8.2-alpha. But for me (dynamical textures)
it works worse than the one I compiled form Lloyd's sources,
using --disable-seekpipe.

My problem and solution is that I can only feed geometry via
FIFO, if I do it via stdio it usually breaks (seekback errors
seem to be not fatal when reading from FIFO, they just give some
(additional) stutter).

I suppose Geomview was not designed to be a very efficient real-time
displayer, especially because it can only read textures from
disk and not remember them. Moreover, internal dicing is very
slow (it is bad to read a large texture and use s,t to tile it)
so it is better to read small PGM's of the order of 100 kB and
tile them explicitly within a MESH structure (even if spread
across a few mesh elements).

I think Geomview deserves real treatment of the seekback
thing and of the texture input mechanism (memory is plentiful),
because its concept is fantastic. Unfortunately I have neither
time nor the ability to do so, I just compiled a heap of
Geomviews and found a working one more or less by trial and
error on configure options (on newer kernels/gcc's, that is; on
2.4. it still used to work kind of normally).

The easiest installation was in fact on Solaris. Yes,
I'm from the fifties too. And I hope I missed something and
Geomview is actually working well ;-)
