Capturing and Rendering with Incident Light Fields

This paper presents a process for capturing spatially and directionally varying illumination from a real-world scene and using this lighting to illuminate computer-generated objects. We use two devices for capturing such illumination. In the first we photograph an array of mirrored spheres in high dynamic range to capture the spatially varying illumination. In the second, we obtain higher resol...

Efficient Illumination by High Dynamic Range Images

We present an algorithm for determining quadrature rules for computing the direct illumination of predominantly diffuse objects by high dynamic range images. The new method precisely reproduces fine shadow detail, is much more efficient as compared to Monte Carlo integration, and does not require any manual intervention.

Building a Pipeline for Gathering and Rendering With Spatially Variant Incident Illumination Using Real Time Video Light Probes

Lighting plays an important part in computer graphics. When making photo realistic renderings the ultimate goal is to generate an image that would be indistinguishable from a real photograph or to seamlessly integrate a synthetic object into a photo. One of the key elements is to get correct lighting and shading in the rendering since the human vision is very well attuned to subtile variations ...

Quantization Techniques for Visualization of High Dynamic Range Pictures

This paper proposes several techniques that enable to display high dynamic range pictures (created by a global illumination rendering program, for instance) on a low dynamic range device. The methods described here are based on some basic knowledge about human vision and are intended to provide \realistic looking" images on the visualization device, even with critical lighting conditions in the...

Realistic Materials and Illumination Environments

Throughout its history, the field of computer graphics has been striving towards increased realism. This goal has traditionally been described by the notion of photorealism, and more recently and in many cases the more ambitious goal of perceptual realism. Photo-realistic image synthesis involves many algorithms describing the phenomena of light transport in a scene as well as its interaction w...
