Contribution

The paper presents a novel adaptive ray-tracing technique that significantly improves computational efficiency in astrophysical image synthesis.

Findings

Achieves over 4x speed-up compared to fixed resolution methods

Reduces the number of pixels needed in the final image

Demonstrates effectiveness in astrophysical simulation scenarios

Abstract

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 (AIR) 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 >~ 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.
