Fast Shading and Shadowing of Virtual Objects Using Shadowing Planes in Mixed Reality

Interactive Shading and Shadowing for Mixed Reality

For merging real and virtual worlds, the following three aspects have to be taken into account: geometry, illumination and time. In this paper we propose the framework to project shadow of real objects on virtual world for seamless mixed reality environment. We have also developed the system such that ser in IPT illuminate virtual and real world with virtual light, shadow of real objects is pro...

Real-time Soft Shadows in Mixed Reality Using Shadowing Planes

Shading and Shadowing of Architecture in Mixed Reality

We propose a simple method to express shading and shadowing of virtual objects in Mixed Reality especially appropriate for static architecture models in outdoor scenes. We create the shadows of the virtual objects in a fast and efficient way using a set of pre-rendered basis images and shadowing planes. The proposed method is limited in interactivity but can operate in near real-time.

Shading and shadowing with linear light sources

In virtually all rendering systems, linear light sources are modeled with a series of point light sources that require considerable computing resources to produce realistic looking results. A general solution for shading surfaces illuminated by a linear light source is proposed. A formulation allowing for faster computation of the di use component of light re ection is derived. By assuming Phon...

Real-time Illumination and Shadowing by Virtual Lights in a Mixed Reality Setting

We present a method of using virtual lights to illuminate real objects in a Mixed or Augmented Reality setting. This method includes the casting of shadows between those virtual and real objects in real time. Finally we show multiple practical examples of how virtual illumination can be used in a Mixed Reality setting using our method.
