Focus convergence conflict (AC-conflict or VAC) is the main visual bottleneck of 3D and virtual reality technology. 3D Lightfield technology overcomes the focus - convergence conflict problem. The light field 3D is simple in optical structure, which enables 3D rendering of full-resolution of a light field without a significant increase in the amount of data. The observer can receive real 3D spatial scenes and focus on any depth of the scene. Filmed at the I-Zone startups and New Tech Demos area at the SID Display Week.
