Researchers have developed RayPE, a novel positional encoding method for video diffusion transformers that enhances 3D awareness. Unlike existing methods that use camera grid coordinates, RayPE incorporates 6D Plucker coordinates to capture the geometric relationships between camera rays. This approach decomposes attention scores into content and geometry terms, both found to be essential for performance. The method is lightweight, adding less than 0.1% parameters to existing models, and has demonstrated improvements in camera controllability, 3D consistency across frames, and overall video quality.
