The usage of open-source and easy-to-modify programme code for spatial visualisation of fast-evolving physical phenomena directly in the course of supercomputer calculations becomes relevant in design, research, construction and subsequent analysis of the validity of the simulated processes in resource-intensive numerical experiments, which is especially important in the study of non-stationary processes in continuum mechanics. Such visualisation has to have minimal impact on computational processes and allow for setting rheological parameters of simulated physical environment and criteria for dynamic and hybrid restructuring of computational processes. Almost any computational platform have embedded graphical means for visualisation of spatial geometrical objects using multi-core processors, which may provide solution to the formulated problem in full measure for parallel visualisation of the current results without substantial impact on the core computational processes. In the present research work we study one possible version of software suite which is based on graphical programming environment OpenGL, surrounded by tools for working with time and interval timers, input devices and text data views at the lowest possible level of direct input/output and interrupt processing in Windows OS.
