We present a technique for efficiently generating photo-realistic pictures of halos. First, we describe an algorithm for producing images of halos from physical parameters supplied by the user. The problem with the resulting images is that they are sampled in a non-uniform way. Then, we propose a specific algorithm for reconstructing the uniform version of these images from their non-uniform sampling. With this technique, we obtain computer-generated halos looking as if they had been natural scenes captured by a camera.
