The image was produced using VMD molecular visualization and analysis software and was rendered by John Stone's Tachyon parallel ray tracing package. The model of the STMV was built using VMD as well. The ions were placed using a CUDA-based GPU-accelerated electrostatics algorithm, also included in VMD. The final Tachyon renderings used ambient occlusion lighting, which helps highlight pockets and cavities in the surface of the virus capsid that can be hard to see clearly with more commonly used direct lighting and depth cueing techniques.
