Systems and methods for computer simulation of detailed waves for large-scale water simulation

A system comprising:

• one or more processing units;
• one or more memory units storing instructions thereon that, when executed using the one or more processing units, cause the one or more processing units to execute operations comprising:
• precomputing one or more wave profiles;
• storing the one or more wave profiles as a texture;
• executing a texture lookup using the texture to compute one or more fluid height values based at least in part on the one or more wave profiles;
• and
• rendering a fluid surface based at least in part on the one or more fluid height values.

A method comprising:

• precomputing one or more wave profiles;
• storing the one or more wave profiles as a one-dimensional (1D) texture;
• executing a texture lookup using the 1D texture to compute one or more fluid height values based at least in part on the one or more wave profiles;
• and
• rendering, using a pixel shader of a graphics processing unit, a fluid surface based at least in part on the fluid height values.
