Abstract: Approaches presented herein provide for the generation of images involving one or more particle simulations to represent visual features or objects such a smoke or fire. Translucent sprites having similar material properties can be grouped, and a single intersection of a traced ray determined with respect to a boundary of the group. A single call to a hit shader (or other such component) can be performed for the sprite group as a whole. The individual sprites can be reoriented in the hit shader as appropriate, such as with respect to the direction of the traced ray or orientation of a main camera used for the image, but also to account for reflections, refractions, diffractions, or other such secondary effects. Since the sprites have similar material properties, the locations of the intersected sprites of the group can be used to determine and blend color values for the sprites, to be returned as a single color value for the ray with respect to the entire sprite group.
