Perspex machine: VI. A graphical user interface to the perspex machine

Perspex Machine X: software development

“…This library does not provide the transreal trigonometric functions defined in. 8 The GUI provides functionality similar to the previous version, 6 but also adds mouse look. This is an alteration of the virtual camera's yaw and pitch with, respectively, horizontal and vertical motions of the mouse.…”

“…6 It continues to use the hyperplane for builtin functions; it continues to use the hyperplane for user-defined constants, variables, and functions; and it reserves the hyperplanes for recursive function calls. The allocation of program elements to perspex space is handled by a perspex-space-manager within the compiler.…”

“…6 The GUI interfaced to a simulation of the perspex machine implemented in C ++ that, in turn, made heavy use of the LEDA library to perform rational arithmetic. 6 The simulation accessed 4D perspex space in linear time.…”

“…6 The GUI interfaced to a simulation of the perspex machine implemented in C ++ that, in turn, made heavy use of the LEDA library to perform rational arithmetic. 6 The simulation accessed 4D perspex space in linear time. This was sufficient to operate on 600 perspexes in real time as demonstrated in an implementation of Dijkstra's solution to the travelling salesman problem.…”

“…All previous perspex compilers, 5 GUIs, 3,6 and simulators 3,6 were one-off research developments aimed at supporting the C programming language. This language was chosen as a target because it is a relatively simple language that exercises much of the imperative programming paradigm, and because there are good compiler-generator tools for C. In future, we expect to switch effort to developing a specialist language for the perspex machine, but, for the time being, the discipline of implementing a standard language is beneficial.…”
