Luxion Gets Patent for Editing HDR Images in KeyShot

Rendering software ability to edit high dynamic range (HDR) images gives it an edge.

Luxion, developers of the KeyShot rendering suite, have announced that they have secured a patent from the U.S. Patent and Trademark Office. The patent, which is the third secured by the company, covers “live editing and integrated control of image-based lighting of 3D models.”

But what’s that mean?

In rendering and lighting suites today, one of the most effective ways of adding realism to a scene is to include high dynamic range (HDR) photography taken from the natural world. In essence, renderings can be improved by taking an HDR photo of a natural setting such as a park or the interior of a warehouse. With an HDR photo in hand, the lighting scheme of a scene can be enhanced by using the HDR image to define the omnidirectional lighting arrangement that lends reflections, caustics and other natural lighting phenomena to an image. The result is an image that closely replicates how real light would interact with the modeled object, adding significant realism to rendered images.

Although HDR images aren’t new to the rendering and lighting worlds, the ability to adjust these images by selecting the areas of a model that need to be lit is a major leap forward in terms of improving rendering ease of use for creating realistic images.

“Creating, modifying or adjusting image-based lighting has always been difficult in, or disconnected from, rendering software,” said Claus Wann Jensen of Luxion. “This solution not only provides a new method for adding and adjusting light, but also provides instant visualization of the light in the model environment.”

With the announcement of this patent, KeyShot is further establishing itself as a major player in the world of rendering. Whether companies are producing graphics for advertisements, designer reviews or other functions, KeyShot’s streamlined workflows and ease of use make a compelling case for adoption.

KeyShot’s rendering technology can be integrated into a number of CAD packages, including Solid Edge, Fusion 360, Creo, SOLIDWORKS and many others.
