Seattle, WA - February 6, 2012 - Sundog Software updated its Triton Ocean SDK, used by training simulators and games for realistic visualization of the ocean and other bodies of water. Triton version 1.3 now includes ship wakes suitable for training purposes and ship identification, together with enhanced support for simulators that model the entire Earth.
"Our top request for Triton was the addition of the trails behind ships, known as turbulent wakes or propeller backwash," said Frank Kane, Founder of Sundog Software. "Triton 1.3 models these wakes based on the ship beam width and length specified, making them useful for ship identification from a distance. These trails work together with Kelvin wake effects that displace the ocean surface behind the ship in 3D."
Triton 1.3 also improves support for virtual environments that span the entire Earth, using what are known as geocentric or Earth Centered Earth Fixed (ECEF) coordinate systems. The large distances involved in these types of environments often stretch the boundaries of a computer's mathematical precision, but this latest revision preserves the quality of ocean images and animation even under these conditions. This new revision also improves the accuracy of height tests against the ocean surface, allowing for ships and other objects that move realistically with the waves being simulated.

"We feel really great about the stability and feature set of Triton with this release," continued Kane. "Users just tell Triton about the local wind conditions and where the ships in the scene are, and thousands of realistic waves complete with wind-blown spray effects and wakes get produced at over 100 frames per second on commodity hardware."
