The program which made these images was developed on the DEC
VAX11/780 running VMS in 1983. This computer had a frame
buffer which made by Mr. Horikita. This program was written
with VAX FORTRAN, and using scan-line Z buffer algorithm
with texture mapping. The transparency effect was realized
in the individual (and very slow) algorithm.
This image was made by ANIM,
which was a simple scan-line based renderer. This program
was originally developed on the NEC PC-9801E (8086 8MHz with
8087) with CI-C86 in 1984. It used scan-line hidden surface
elimination algorithm making good use of span coherency. It
marked 400-800 polygons/sec.
The program which made these images was SOL, which was also a
scan-line based renderer. It could handle the quadratic
surfaces and the Boolean combinations. This program was
originally developed on the NEC PC-9801E (8086 8MHz with
8087) with CI-C86 in 1985.

The program which made this image was SS, which was also
scan-line based renderer. The object in this image consists
of four "positive" cubes and one "negative" yellow cube.
This program used an algorithm which is similar to
Atherton's scan-line hidden surface removal procedure for
CSG. I used pattern matrix to describe Boolean combination
to reduce the number of one dimensional Boolean operation on
the end of sample span. This program was developed on the
Sun4/330 running SunOS 4.0 in 1993, and it has been ported
to the PC running Windows-NT 3.5.1 since. It marked about
20,000 polygons/sec by Pentium 100MHz, and it will be able
to accelerate up to 40,000-80,000 polygons/sec.
These images were made by StrataVision 4.0J.
