Sundog Adds God Rays, Cloud Shadows to SilverLining SDK

Orlando, Fla. (January 29, 2013) – Sundog Software released version 2.7 of its SilverLining Sky, 3D Cloud, and Weather SDK today, rolling out several new visual effects for game and simulation developers.

Crepuscular Rays in SilverLining 2.7 “SilverLining 2.7’s most eye-catching improvement is crepuscular rays, AKA God rays” said Frank Kane, founder of Sundog Software LLC. “Beams of light emanate from the sun when it’s behind clouds, leading to visually stunning scenes with no extra effort from the developer.” This update also provides new “shadow maps” that developers may use to cast shadows from the clouds on the ground, and “environment maps” that may be used for reflecting SilverLining’s simulated sky on water and other objects. These environment maps may be used with Sundog’s Triton Ocean SDK to produce realistic sky reflections on Triton’s virtual oceans.

Real-time Cloud Shadows in SilverLining“It’s a big update,” continued Kane. “In addition to new ray, shadow, and reflection capabilities, we’ve expanded support for very large cloud areas to DirectX-based engines, made some fixes to our lens flare and real-time cloud growth effects, enhanced our support for customers using multiple viewports, and improved our integration examples for the Ogre engine and for C# development.”

SilverLining 2.7 is available now at . Packages are available for C++ or C# developers on Windows, Mac, Linux, or Android platforms. Integration kits are available for OpenGL, DirectX, Havok, OpenSceneGraph, Ogre, Unity, and more.
