Fullparallax

Fullparallax is a term used to describe a depth rendering approach that preserves parallax cues across all viewing directions, enabling depth perception as a viewer moves laterally, vertically, or around the scene. It contrasts with traditional 2D parallax effects that simulate depth primarily through horizontal shifting of layers, such as parallax scrolling.

In practice, fullparallax is associated with autostereoscopic displays and light-field rendering, where a scene is captured or synthesized as a wide set of viewpoints that cover a broad angular range. This enables parallax to be perceived in multiple axes and across depth, providing a more complete sense of three-dimensional structure without requiring special glasses in some systems. The goal is to deliver a continuous, viewer-dependent view that changes realistically as the observer’s position changes.

Implementation approaches include multi-view capture with dense view sampling, depth-aware or view-dependent rendering, and volumetric or light-field display technologies. Some systems render hundreds of views or use dense depth maps and proper occlusion handling to maintain consistent parallax across viewpoints. The technique often relies on significant data bandwidth, storage, and processing to render or transmit many viewpoints in real-time.

Applications span high-end digital signage, product visualization, immersive gaming, and VR/AR experiences that aim for glasses-free 3D or enhanced depth perception. Limitations include substantial hardware requirements, challenges in achieving accurate depth and occlusion, crosstalk between views, and restricted viewing zones. The term is not universally standardized; in some contexts it denotes the aspiration of true multi-directional parallax rather than a single proprietary technology.
