We developed Mixed Reality (MR) content that reconstructs the ancient capital of Asuka-Kyo and applied a fast shading and shadowing method that uses shadowing planes. Subjective evaluation with a head-mounted display showed that viewing this content increased the audience’s knowledge both of Asuka-Kyo and of MR technologies. We also conducted impression evaluation tests with and without shading...

Deferred shading has gained popularity in recent years, but some aspects about its performance are still unclear. In this work we make an initial evaluation of deferred shading’s performance and evaluate it with respect to the number of light sources, the type of light sources, the illumination model, the complexity of the scene, and the influence range of the light sources. We compare measured...

Almost all graphics architectures today support Gouraud shading, linear color interpolation between vertices; system designers aim toward a Phong shading model, linear interpolants of surface normals with a lighting model that supports both diffuse and specular components, as a superior means of rendering accurate images. However, the Phong model still retains serious artifacts. In this paper, ...

Numerous techniques have been developed to perform advanced shading operations in real time. The real-time versions vary greatly from their original implementations due to the constraints of existing hardware and programming libraries. This paper introduces a grammar for articulating these modern real-time shading pipelines. We survey the existing techniques, using the grammar to classifies the...

We present a novel multi-view reconstruction approach that effectively combines stereo and shape-from-shading energies into a single optimization scheme. Our method uses image gradients to transition between stereo-matching (which is more accurate at large gradients) and Lambertian shape-from-shading (which is more robust in flat regions). In addition, we show that our formulation is invariant ...

The RenderMan interface has been proposed as a general interface to rendering systems, yet only a few implementations of the interface exist. In this paper we describe the implementation of the RenderMan interface on a general rendering architecture that supports various rendering algorithms. Speciically we discuss the implementation of the RenderMan Shading Language and its integration into ou...

Photorealistic rendering of human hair has been a challenge task in computer graphics for many years. These challenges include coming up with a practical yet accurate light scattering model for individual hair fibers, handling the complex geometry of large number of hair fibers, properly simulating the global illumination and complex interaction of light and shadows between the hair strands, an...

The 'colour-shading effect' describes the phenomenon whereby a chromatic pattern influences perceived shape-from-shading in a luminance pattern. Specifically, the depth corrugations perceived in sinusoidal luminance gratings can be enhanced by spatially non-aligned, and suppressed by spatially aligned sinusoidal chromatic gratings. Here we examine whether colour contrast can influence perceived...
