Image Based Shadowing in Real-Time Augmented Reality

Image Based Shadowing in Real-Time Augmented Reality

This work presents an approach to render appropriate shadows with Image Based Lighting in Augmented Reality applications. To approximate the result of environment lighting and shadowing, the system uses a dome of shadow casting light sources. The color of each shadow is determined by the area of the environment behind the casting light source. As a result it is possible that changes in the ligh...

A scalable GPU-based approach to shading and shadowing for photorealistic real-time augmented reality

Visually realistic Augmented Reality (AR) entails addressing several difficult problems. The most difficult problem is that of rendering the virtual objects with illumination which is consistent with the illumination of the real scene. The paper describes a complete AR rendering system centered around the use of High Dynamic Range environment maps for representing the real scene illumination. T...

Editing Real World Scenes: Augmented Reality with Image-based Rendering

We present a method that using only an uncalibrated camera allows the capture of object geometry and appearance, and then at a later stage registration and AR overlay into a new scene. Using only image information first a coarse object geometry is obtained using structure-from-motion, then a dynamic, view dependent texture is estimated to account for the differences between the reprojected coar...
