Wormhole Canvas

On physical canvas, color can only diffuse in the continuous 2D space. To break this constraint, this paper proposes wormhole canvas, on which the pervasive one-way wormholes can continually teleport color to distant locations. Various results show that different placements of wormholes can produce different stylized renderings. Wormhole canvas shows that NPR(Non-Photo realistic Rendering) can be the artistic media of the future, surpassing the capability of traditional artistic media.
