Abstract
Systems and methods generate a hybrid lighting model for rendering objects within an image. The hybrid lighting model includes lighting effects attributed to a first source, such as the sun, and to a second source, such as spatially-varying effects of objects within the image. The hybrid lighting model may be generated for an input image and then one or more virtual objects may be rendered to appear as if part of the input image, where the hybrid lighting model is used to apply one or more lighting effects to the one or more virtual objects.
