This study introduces a novel subroutine for creating function shape relief maps. It enables direct diagrammatic representation of surfaces using a line printer and variable blackening intensity.

Area of Science:

Computer Graphics
Scientific Visualization

Background:

Representing function shapes aids in understanding complex data.
Traditional methods for 3D surface visualization often rely on plotters and step-by-step level curve tracing.

Purpose of the Study:

To describe a new subroutine for generating diagrammatic representations of functions.
To enable direct surface visualization using a line printer.

Main Methods:

Development of a subroutine for direct surface representation.
Utilizing a line printer for output.
Employing blackening intensity proportional to function values.

Main Results:

Successful diagrammatic representation of tridimensional surfaces.

Related Experiment Videos

Direct visualization achieved without traditional plotters.

Intensity of blackening accurately reflects function values.

Conclusions:

The developed subroutine offers an efficient method for visualizing function shapes.
Direct line printer visualization provides a practical alternative for surface representation.
