5d covariance tracing for efficient defocus and motion blur

HIGHLIGHTS

• who: Laurent Belcour and collaborators from the Grenoble University have published the research work: 5D Covariance Tracing for Efficient Defocus and Motion Blur, in the Journal: (JOURNAL)
• what: The authors show that any first-order motion can be handled using a 5D change of coordinates that expresses interactions in the static frame of the moving object. Because the authors focus on atomic operations, formulae are easy to derive for the full 5D spectrum. The authors focus on single-bounce paths (i.e. lens-object-light) but the technique has potential for arbitrary light paths. The . . .
