Area Light Sources for Real-Time Graphics

In an effort to extend the sorts of lighting models used in real-time computer graphics, this paper presents several area light source models, including Lambertian and Phong illumination from constant and cosine-falloff hemispherical light sources, constant subhemispherical light sources, and constant polygonal light sources. The subhemispherical lighting model can also be used to represent ill...

New acquisition techniques for real objects and light sources in computer graphics

Accurate representations of objects and light sources in a scene model are a crucial prerequisite for realistic image synthesis using computer graphics techniques. This thesis presents techniques for the efficient acquisition of real world objects and real world light sources, as well as an assessment of the quality of the acquired models. Making use of color management techniques, we setup an ...

COMPUTER GRAPHICS OPTIQUE Optical Superposition of Projected Computer Graphics

We present some ideas and demonstrations for a hybrid projectorbased rendering and display technique we call Computer Graphics Optique. Instead of partially overlapping projected images to achieve a wide-area display, we completely overlap projected images on top of each other to achieve the addition of light and color in an “optical composition buffer.” The idea is to use the optical compositi...
