Live Coding for Artists and Designers (lgm2026)

Our favorite Free/Libre and Open Source tools for graphics provide numerous features that facilitate our creative work. But what if the idea we have in mind is too hard to achieve in a reasonable amount of time? Possible solutions include kindly asking the developers or trying to implement them ourselves. What if our needs are too niche? What if we are looking for a feature to be used just once? Command line tools like ImageMagick or FFmpeg can help in some situations, but designing via CLI-arguments is not precisely ergonomic. In this live-coding talk I want to demonstrate how to write simple tools using OPENRNDR to generate and transform bitmap, vector, 3D mesh and video files that can be further edited in design tools typically discussed at the LGM. OPENRNDR is a Kotlin-based Free/Libre Open Source framework for creative coding. It provides a wide range of algorithms and tools to work with contours, images, GPU filters and more, and can help automating repetitive or algorithmic tasks in media production. Let’s rewire our existing tools by quickly prototyping new ones!
