The Idea: Anaglyph 3D Effect

The central concept was inspired by anaglyph 3D technology, which originated in the early 20th century, gained widespread popularity in the 1950s, and saw a nostalgic resurgence in the 2000s. These early stereoscopic methods used red and blue channels to deliver slightly offset images to each eye, producing a compelling sense of three-dimensionality. Drawing on this perceptual mechanism, we created a visual system in which red and blue line patterns are generated algorithmically and overlaid with precise displacement, tricking the viewer’s depth perception even without the use of color filters or 3D glasses.

Creating First Graphics with Processing

Using Processing, we developed a generative script that creates point-based structures and connects them conditionally based on color grouping. Two distinct but structurally related sets of lines — one red, one blue — are exported separately and plotted using AxiDraw. Their recombination on paper produces a binocular disparity effect: when viewed, the eye attempts to resolve the misaligned layers, producing a virtual sense of dimensionality and vibration.

Testing The Pen Plotting

Throughout the process, we conducted extensive material tests on watercolor paper, corrugated cardboard, and transparent plastic foils to understand how surface texture, ink absorption, and physical spacing affect the final visual experience.

Prototype 01: The Optimised Hexagon Pattern

 A pseudo-3D hexagonal pattern, where alternating red and blue line structures converge into a pulsating visual grid. The illusion of depth emerges from slight horizontal shifts and rhythmic repetition, evoking a tactile, volumetric sensation.

Prototype 01: Plotting on Corrugated Cardboard

We tried different materials to print on, such as corrugated cardboard.

Prototype 01: Pen Plotting on Watercolour Paper

Some materials were a better fit than others. Watercolor paper worked quite well.

Prototype 02: Making the Anaglyph 3D Kaleidoscope

A kaleidoscope-like layered composition, constructed with transparent plastic sheets positioned at varying physical distances. This setup amplifies the optical illusion by introducing real-world spatial layering, allowing light and perspective to shift the perception of the algorithmic pattern dynamically.
