Here are 3 new versions of the QRT1.4 program.
Version QRTFFP uses the Motorola Fast Floating Point format to
speed things up as much as possible with a stock amiga
Version QRTLIB uses the 1.3 math libraries to speed things up in a
generic way on machines with MC68881 Floating Point Processors.
This is for CMI processor accelerators etc which interface the
MC68881 as a peripheral processor
Version QRT881 is a full blown 68020/68881 version which uses inline
68881 instructions for fastest possible code.
I also included a version of QRTPOST which should be slightly
faster than the stock version.
Have fun ray tracing! All units compiled using Lattice C 5.0
with Global Optimizer patch on.
File Temp.qrt is a sample ray trace with just a floor and no objects.
Should look like a checkered floor when done. I also included ray2
for you raytrace fans but it is the same ray2 as supplied with the regular
1.4 QRT stuff.
