The same scene. The same image rendering time. Very different results. The noisy and pixilated image on the left was created with the conventional “ray marching” photon mapping technique while the images on the right was created using the new “beam estimate” approach to photon mapping that is computationally more efficient.

UC San Diego computer scientists have created a fog and smoke machine for computer graphics that cuts the computational cost of making realistic smoky and foggy 3-D images, such as beams of light from a lighthouse piercing thick fog.
