Distortion Correction Approaches for Curved Monitors (DAAV)

Current consumer-grade curved screens can provide a horizontal field of view of up to 120° and present an attractive option for content consumption in a desktop environment. However, traditional real-time rendering algorithms produce incorrect results for curved monitors if they are not adapted accordingly. For example, straight horizontal lines in a rendered image will be perceived to be curved on such displays. This property reduces the appeal of heavily curved monitors and limits their usefulness.

Unfortunately, rasterization-based graphics hardware is designed to render geometry onto a planar surface called the image plane. The distortion correction performed on such hardware can introduce a significant computational overhead and reduce image quality. We evaluate and compare various distortion compensation approaches for ultra-wide curved monitors. Additionally, we aim to improve on these approaches by utilizing modern hardware features like mesh shaders.
