Users are free from the optimization of page allocation for each type of data. Since numbers are always represented as immediate data, no garbage is generated by numeric computation. Solid models can be defined from primitive bodies using CSG set operations. Mass properties, interference checking, contact detection, and so on, are available. Postscript output compatible with idraw and PICT format graphics description for Macintosh can be generated.
Edge based image processing facility is provided.
Three levels of Xwindow interface, the Xlib foreign functions, the Xlib classes and the original XToolKit classes are provided. Functions written in C or other languages can be linked into EusLisp. Bidirectional call between EusLisp and other language are supported. Call-back functions in X toolkits can be defined in Lisp. If EusLisp runs on multi-processor machines, it can utilize parallel processors' higher computating power.
