With“Phototrophic Plants”as the main concept, image designs are projected onto plants, translating and enhancing the attitude and traits of the four main characters:“Rice, Fruits, Mushrooms, and Tea Leaves.” Using the monitors as a patchwork through the corridor, through continually stacked and abundant images, along with unending compression of space, a fantasy blend of“organic”and“geometric”coexistence. This will allow the audience to obtain a sense of openness in all areas when entering the indoor exhibition area.

To meet the project's demands, visual effects were developed specifically for plants on-site. Since the work had to be done outdoors at night to avoid light pollution, time was limited. To tackle these challenges, two tools were created:

• Projector-Camera Calibration Using Gray Code Patterns

This technology allows visual effects personnel to simulate how images appear from the projector's perspective. Gray code patterns are projected onto the plants, and a camera records the patterns. Using computer calculations, the camera's view is converted into the projector's perspective. Existing tools lacked colour and accuracy, so a custom solution was developed to meet higher quality requirements.

• Real-Time Visual production Using NDI

To streamline the process, a system was created for real-time projection editing. Plugins for software like Photoshop and After Effects enable instant visual updates to the projection system without repeated exporting. Using NDI technology for image transmission, the system also supports a wireless workflow via Wi-Fi.
