RAYFORM™ provides a service to luxury companies to integrate its proprietary light redirection technology into their products. Their technology brings never-before-seen design opportunities to luxury products and packaging. The key to this technology is a computer algorithm that calculates the 3D surface needed to create any target image from light. By slightly modifying the shape of a transparent or reflective surface to the surface computed with the algorithm, incoming light is redirected to form amazingly clear and highly detailed light images on nearby surfaces. This light can come from any directed light source, e.g. a flash light, a spotlight, or the sun.

RAYFORM™ is a spin-off of the Swiss Federal Institute of Technology (EPFL) based on the founders’ award-winning research on computational caustic design and engineering presented at top research conferences. For more information about the scientific underpinnings of the technology, see our research website.

Frequently Asked Questions

Q: How does RAYFORM technology work?

A: We modify the surface of an object so that light rays hitting it are redirected to produce an image. It’s the same principle as a magnifying lens or a curved mirror. Using our patented algorithm, we calculate the surface needed to produce any image out of light. With our method, we can produce any kind of image including highly detailed photos or logos. And since we concentrate the incoming light, the light images are brighter than their surroundings.

Q: What is RAYFORM's business model?

A: Based on our client's specifications, we calculate the 3D surface using our algorithms which we send in the form of a 3D file. We charge a fixed cost per calculation, plus a royalty based on the number of objects produced with this surface. 

Q: Do you change the interior of the object?

A: No, we only modify the surface of the object. The base material and its internal structure stays exactly the same, leading to a simple manufacturing process.

Q: How are RAYFORM surfaces fabricated?

A: We integrate our surfaces into the existing industrial process of the product. If the process involves molding, we simply change the mold by providing a 3D file to the mold manufacturer. No other changes to the pipeline are necessary. Otherwise, it depends on the manufacturing process. Contact us so we can discuss about your specific product/pipeline.

Q: Will the light images be visible in any configuration?

A: We calculate the image for one specific configuration of light, object, and position of the image. The image will be best reproduced around this configuration. When moving away from this ideal configuration, the image will slowly warp and disappear. Have a look at this video to see an example of these dynamics.

Q: What kind of light is required for the image to appear?

A: The image will appear with any kind of directed light such as light coming from the sun, a flashlight or a spotlight. It will not work with “soft” lights like fluorescent tubes.

Q: Are the images visible in the object itself?

A: In most cases the image cannot be seen on the object. The surface is linked to the image mathematically, but by eye usually appears slightly wavy (depending on the target image.) For reflective objects, the waviness is often imperceptible. The image will appear as if by magic only when the object is illuminated.

Q: Do I have to design a new product or can I augment an existing design?

A: If you already have a design with flat (or very slightly curved) faces or areas, we can modify the existing design. Otherwise, we provide consulting services in order to match the design to work with our technology. Please contact us for more details.
