Image-Based Rendering for Industrial Applications

by MIRAGES is to capture a single photograph of the scene that we want to reconstruct. The second step is to position the 3D model (including the light sources), that can be built manually using the real image, thanks to a classical modeler such as Maya (Alias|Wavefront). Once the parameters of the camera (position, orientation, ...) have been automatically recovered, our image-based rendering software may recover a full BRDF (Bi-directional Reflectance Distribution Function) of all the objects in the scene. Starting with a first assumption about the reflectances of these surfaces, we generate a computer graphics image using an advanced photorealistic rendering software, called Phoenix, developed by our team. Phoenix is a global illumination renderer that can produce photorealistic images in a very short time (faster than current radiosity software). Phoenix takes advantage from the internal architecture of the computer, to greatly accelerate the process of image generation.
