"Grasshopper4D"

Leveraging Grasshopper and Python to create advanced animations, adding the fourth dimension of time to 3D parametric models. These animations serve as a means to explore and develop new concepts and algorithms.

MOBIUS ROLLER-COASTER, v1 & v2

2023 | Two of a series of "satisfying loop" animations, entirely created in Grasshopper. These animations have been created to utilize advanced geometries and to explore how to improve visualizations of Grasshopper models.

PARTY HITS: A BLAST FROM THE PAST

2022 | A series of parametric animations made with and for artist Loes Roskam for her graduation exhibition "Party Hits: A Blast from the Past".

An exhibition about music streaming algorithms, big data and human connectivity.

MOBIUS DONUT

2023 | A third installment of animations based on the mobius strip. This one is inspired by one of the default Windows backgrounds.

Made with native Grasshopper components.

STRING ART
PYTHON ALGORITHM

2019 / 2023 | Various artists, such as an artist called “Cvern”, recreate famous portraits by threading a string through a ring of pins. As a past-time project, I challenged myself to develop a script from scratch that automatically generates such ‘string art’ of any inputted image - and generate an animation accordingly.

In 2019, this script was a back-and-forth workflow between Grasshopper and Python code. In 2023, I've been recreating this script using pure Python, as a means to experiment with various libraries and advanced concepts.

ROLL OF THE DICE

2021 | A series of portraits visualized by an array of dice, generated by an image processing script (Grasshopper + Python).
