Abstract: Techniques for stochastic ray tracing for rendering digital assets are described and are implementable to efficiently render digital assets within scenes. In an example, a digital asset that includes transparent three-dimensional primitives is received to be included in a scene. Candidate intersections between a ray traced from a viewpoint within the scene and one or more of the primitives are identified. An intersection is selected from the candidate intersections based on binarized opacity values and distance values to the viewpoint determined for each of the candidate intersections. The digital asset is then rendered within the scene by applying a color value associated with the selected intersection to one or more pixels.
