VR-HTGS enables artifact-free, eye-tracked foveated rendering of 3D Gaussian Splatting in VR at 120+ Hz by dynamically adapting the tile-based rasterizer to a heterogeneous tile layout following the gaze position, without sacrificing perceptual quality or model fidelity.

We investigate the influence of temporal frequency and eccentricity of a stimulus on the magnitude of perceived velocity in the periphery, building a model to predict the scaling factor for perceived velocity deviations relative to eccentricity.
