[comp.sys.amiga] QRT

dan@ivucsb.UUCP (Dan Howell) (03/27/89)

The documentation for the QRT ray tracer that recently appeared o
comp.sources.misc or alt.sources that it was developed on an amiga, and
also says that in order to display the resulting picture files a program
called RAY2 is needeed to convert the raw image into IFF.  This program was
not included in the distribution.  Does anyone know where this is available?

Could anyone direct me to (ftp) or mail me the executables for QRT
including the post processor.

I have the source, but can't seem to get it to work after compiling
with Lattice 5.02.
If possible , I would like to have a 68020/68881 copy as well as a 68000
version...Thanks in advance

(Ps. If you're in the sending mood...DBW exetable would be neat)

I thought I heard someone mention that the source for QRT1.5 was
available somewhere.  If so does anyone know where?

Has anyone had any luck with QRT?  I have the source code, and wrote my own
make file, and it compiles without errors...
It runs just fine...(2 hours on my Amiga, approx. 20 minutes on an Encore
MultiMax)
the problem is that QRT claims that it's output files should be readable by
RAY2 from DBW_RENDER...this doesn't seem to be the case.

I compiled Olif's new RAY2 and tried it...0 colors used out of 4096
I compiled the old RAY2 on my Amiga.......0 colors used out of 4096
I then tried the original display program....nope...

Anyone?  Is QRT just plain bad?
thanks...

I haven't used QRT in quite awhile; my version is 1.4, I think.
But, running QRT gave me a file with extension `.raw'.  This file
had to be fed to a program called `qrtpost'.  Have you got this?
The output from this program could be processed by `ray2'.

This simple-minded Dillon(tm)-shell script ran everything for me:

	# run a ray-trace
	if $_passed
	    df1:qrt <$_passed.qrt
	    df1:qrtpost $_passed.raw $_passed.tmp
	    df1:ray2 -c 0 -h 0 $_passed
	endif

Don't forget to `up' your stack to a ridiculously high amount, 
and ChangeTaskPri your CLI to something nice like -5.

Sorry to post this here, but I remember seeing a reference to Quick Ray Trace
running in unix.  Since the sun at school is *slightly* faster than my amiga
I thought I would use it to make some pictures.  can anyone send me an ftp
site address for this?

thanks,
