"Endless Green Mountains—Green Beauty Guangdong Immersive New Media Creation Exhibition" utilizes cutting-edge projection technology to create a multi-layered ecological narrative space. Its core focus is to digitally reconstruct the natural landscape and break down physical boundaries through the interaction of light and shadow.
The following details the immersive projection application from three perspectives: technical implementation, spatial design, and interactive logic:
I. Projection Technology Types and Hardware Deployment
1. Laser Engineering Projection System The exhibition utilizes high-brightness laser engineering projectors, featuring airtight dustproofing, long lifespan, and strong color stability, ensuring long-term operation without degradation of image quality. This type of equipment supports multi-channel fusion projection, enabling seamless splicing on complex curved surfaces such as folding and curved screens. For example, the "A Day in the Forest" exhibition area utilizes 15 projectors to simulate the changing morning and evening scenery of the Nanling forest on a folding screen composed of six large screens.
2. Interactive Ground Projection and Circular Screen The "Lush Southern Country" section features a fully enclosed 360° circular giant screen and ground projection screens. The floor features pressure-sensitive devices, allowing visitors to trigger the kapok blossoms to bloom by stepping on them. A circular screen projects a panoramic view of the Danxia landform through a fisheye lens, allowing viewers to rotate the viewing angle with a wave of their hand, creating a "human-scene interaction." This design is similar to the "Data Visualization Floor Screen" at the Shenzhen Longhua Ecological Museum, but with the addition of motion capture.
II. Spatial Narrative and Visual Content Design
1. Dynamic Digital Scroll Technology
Drawing on the 3D modeling and rendering combined with dynamic image synthesis techniques used in the "Green Beauty of Guangdong" exhibition at the Osaka World Expo, this exhibition transforms scanned data from real-world locations such as the Nanling Mountains and Danxia Mountain into a flowing scroll. For example, in the "Here is Peace of Mind" exhibition area, layered rendering techniques are used to overlay the brick and tiled walls of walled houses and the textures of oyster shell walls with the modern buildings of Pazhou, creating a visual montage that folds time and space.
2. Particle-Based Expression of Ecological Symbols
Natural elements are deconstructed into dynamic particles: - Moss is simulated as a swarm of luminescent particles, fading in brightness with sound waves (recorded bird calls); - Mangrove ecosystems simulate tides and root growth using fluid dynamics algorithms. This approach imbues the ecological theme with a sci-fi aesthetic, echoing the philosophical core of Zhuangzi's "On the Equality of All Things."
III. Interaction Logic and Enhanced Perception
1. Multimodal Sensor Fusion
Motion Capture: Kinect sensors detect gestures and movement, triggering scene rotation or information barrages (e.g., analysis of Danxia geological profiles);
Audio-Visual Interaction: A microphone array captures ambient noise intensity, dynamically adjusting projection brightness and forest sound volume, creating a contrasting experience of "the louder, the quieter." 2. Artistic Translation of Ecological Data Real monitoring data, such as mangrove area and bird populations, is transformed into dynamic infographics: Increased silver pheasant populations → increased virtual flock density; Improved water quality → Projected color shifts from brown to blue-green; This gives environmental protection achievements a tangible form.
