A technique is presented for producing synthetic images from numerical simulations, whereby the image resolution is adapted around prominent features. In so doing, adaptive image ray-tracing improves the efficiency of a calculation by focusing computational effort where it is needed most. The results of test calculations show that a factor of greater than or similar to 4 speed-up, and a commensurate reduction in the number of pixels required in the final image, can be achieved compared to an equivalent calculation with a fixed-resolution image.
