Ray Tracing ( specifically Path Traced GI ) is fairly simple given the complexity of 'reality' and light bouncing off or through various materials. The actual algorithms used to bounce/scatter/gather light aren't complex.
Symmetric Encryption is usually a couple matrix multiplies over blocks of data...giving a lot of complextity from a few simple constants and arithmetic ops.
