Introduction
This project explored the limits of projection mapping by transitioning from smooth, predictable surfaces to an organic, uneven shape: a tree. Trees offer a fascinating array of challenges, characterized by their intricate textures, diverse branching structures, and distinct surfaces. My aim was to craft a flexible method for representing this ever-changing format, producing visuals that not only highlighted the tree's inherent design but also ensured clarity and visual appeal. the inspiration for this project came from the digital artist: PhilippFrank. The primary aim of this project was to create a framework for successful projection mapping on unconventional, organic surfaces.
Testing Phase
The testing phase played a key part in understanding how the tree’s essential characteristics—like bark texture, branches, and unique shapes—impacted the clarity and impact of the visuals displayed. In order to use these features to our best advantage, this stage focused on exploring various visual styles to find the most effective combinations.
Key Evaluations:
To find the brightness levels at which images would stay distinct on the rough, uneven bark, I experimented with different light intensities and color contrasts. Brighter colors and greater contrasts worked better overall (sometimes at a disturbing scale for a normal projection), however some combinations highlighted the texture of the tree without overpowering it. At the same time, modifying the projection's angle and distance improved clarity and lessened shadows. Finding the best locations was crucial because branches and uneven surfaces caused the images to appear distorted from certain angles. Lastly, I experimented with several animation rates and found that slower ones tended to stay clear on the tree's surface, while faster ones blurred or disappeared into the texture of the tree. The key to maintaining the images' uniqueness was selecting the appropriate kind of animation.
Creating Basic Outline
From the testing phase, I developed a series of principles for crafting impactful visuals designed for organic surfaces such as a tree. The guidelines considered the visual, technical, and aesthetic elements essential for effectively adapting the projection.
High-Contrast Colors
To enhance visibility against the tree’s naturally dark, uneven surface, it’s essential to prioritize high-contrast colors like white, yellow, and bright pastels. Deep hues and muted shades frequently merged with the bark, diminishing clarity.
Bold and Simple Shapes
The small details frequently faded into the surface of the bark. Employing bold, straightforward shapes contributed to clarity, enabling the visuals to shine even against the complex backdrop of the tree.
Slow, Fluid Animations
Gradual, smooth motions were most effective, allowing images to react to the varied surface without creating blur. Controlling animation speed helped preserve visual clarity and distinguish each visual element. Fast animations typically distorted and reduced clarity.
Textures and Visual Depth
Additionally, incorporating organic patterns and flowing lines emphasizes the tree’s natural texture. This method highlighted the tree's inherent beauty and provided the projection with a more unified and harmonious appearance.
Conclusion
This project established a hands-on approach for projection mapping on natural surfaces, demonstrating that with appropriate visuals, colors, and animations, clearer installations can be attained even on intricate shapes such as a tree. Through the establishment of flexible guidelines, I crafted a method that can be utilized on various unconventional surfaces, presenting an innovative viewpoint on projection mapping that transcends the limitations of standard screens and walls.
Future Applications:
Looking ahead, I’m excited to explore and create systems solely for more organic surfaces. This project highlights the potential for bringing projection mapping into outdoor environments, creating immersive experiences that blend seamlessly with nature.
