Generating interactive narratives as movies requires knowledge in cinematography (camera placement, framing, lighting) and film editing (cutting between cameras). We present a framework for generating a well-edited movie from interactively generated scene contents and cameras. Our system computes a sequence of shots by simultaneously choosing which camera to use, when to cut in and out of the s...

In the computer graphics production environment, artists often must tweak specific lighting and material parameters to match a mind’s eye vision of the appearance of a 3D scene. However, the interaction between a material and a lighting environment is often too complex to cognitively predict without visualization. Therefore, artists operate in a design cycle, where they tweak the parameters, wa...

This paper describes a method of modeling to model shadow play puppet using sophisticated computer graphics techniques available in OpenGL in order to allow interactive play in real-time environment as well as producing realistic animation. This paper proposes a novel real-time method is proposed for modeling of puppet and its shadow image that allows interactive play of virtual shadow play usi...

This paper describes a technique for using a simple shading method, such as the Phong lighting model, to approximate the appearance calculated by a more accurate method. The results are then suitable for rapid display using existing graphics hardware and portable via standard graphics API's. Interactive walkthroughs of view-independent nondi use global illumination solutions are explored as the...

At present, two popular development areas in computer graphics are improvement of interaction behaviour and more realistic graphics. The architecture for a high quality interactive workstation proposed in this work is designed such that both demanding and in a sense competing needs can be served. Calculations for generating realistic full 3-D scenes with lighting, transparency, reflection , and...

BACKGROUND Lighting is used during conventional broiler grow-out to modify bird behaviour to reach the goals of production and improve bird welfare. The protocols for lighting intensity vary. In a field study, we evaluated if the lighting practices impact the burden of Salmonella in broiler flocks. METHODS Conventional grow-out flocks reared in the states of Alabama, Mississippi and Texas, US...

In traditional media such as sculpture and painting, but also in film, a static design process is used during the creation phase. In interactive media dramaturgy can permanently change depending on user interaction or dynamic factors. To be consequent visualizations should react on narration changes, so that narrative content and visualization are consistent. Fig. 1: Visual Artists use graphica...

A BRDF approximation is developed that is suitable for interactive color appearance design in direct lighting provided by environment maps. The BRDFs are approximated as a linear combination of cosine lobes with a fixed set of specular exponents. A nonlinear optimization routine is used to fit the cosine lobes to BRDFs appropriate for a specific color appearance design application: automotive p...

We suggest that the dramatically engaging mediation of an experience of place should be built in as a fundamental capability of a compelling and meaningful virtual environment (VE). Our main objective is to develop flexible interactive techniques that supply VE’s with a coherent context and make the resulting ‘virtual place’ available to the user in a dramatically engaging way. To support the c...

This paper presents a new method for interactive viewing of dynamically sampled environments. We introduce a 3D mesh-based reconstruction called a tapestry that serves both as the display representation and as a cache that supports the re-use of samples across views. As the user navigates through the environment, the mesh continuously evolves to provide an appropriate image reconstruction for t...
