Script to download DOS extender and freeware EASTRAY raytracer (originally developed for the FM Towns) and set up wrapper script to run EASTRAY from the command line via DOSBox on any platform supporting DOSBox.
Running bash download.sh, a sub folder eastraydownload is going to be created. eastray.sh inside that folder can be used to launch EASTRAY.
Syntax: eastray.sh [-v] path/scene.ray
The optional parameter -v shows the progress on raytraced scanlines; leaving it out no DOSBox window will be opened and EASTRAY will run silently.
EASTRAY can read and write both 32K and 16.7M color TIFF images. 32K color TIFFs were commonly used on the FM Towns and can be converted to and from PNG with tiff32k2png and png2tiff32k. For high-quality picture output from EASTRAY, 16.7M color TIFF images are recommended; corresponding 24-bit output can be set in EASTRAY scene files via
