Abstract Ray‐tracing volumetric data may take several minutes to compute a single image from a fixed viewpoint. We present techniques that generate approximate ray‐traced volumetric images in less than one second per image, after a lengthy initialization process is performed. These approximate images are based on methods that interpolate data sampled at locations on a sphere.
