    The problem of human-induced climate change has emerged as one of the grand challenges facing humanity. Advances in scientific understanding in the past 20 years have confirmed the fact of climate change and its likely acceleration, driven primarily by rising carbon dioxide (CO2) levels mostly from fossil-fuel combustion. We must reduce CO2 emissions to stabilize greenhouse g... View full abstract»

    In visualization, we use the terms data, information and knowledge extensively, often in an interrelated context. In many cases, they indicate different levels of abstraction, understanding, or truthfulness. For example, "visualization is concerned with exploring data and information," "the primary objective in data visualization is to gain insight into an information space," and "information visu...

  • Rendering Grass in Real Time with Dynamic Lighting

    Publication Year: 2009 , Page(s): 32 - 41
    Cited by:  Papers (3)
    Request Permissions | Click to expandAbstract | PDF file iconPDF (3127 KB) |  | HTML iconHTML  

    The authors present a real-time grass rendering technique that works for large, arbitrary terrains with dynamic lighting, shadows, and a good parallax effect. A novel combination of geometry and lit volume slices provides accurate, per-pixel lighting. A fast grass-density management scheme allows the rendering of arbitrarily shaped patches of grass.

  • oRGB: A Practical Opponent Color Space for Computer Graphics

    Publication Year: 2009 , Page(s): 42 - 55
    Cited by:  Papers (13)
    Request Permissions | Click to expandAbstract | PDF file iconPDF (6424 KB) |  | HTML iconHTML  

    Designed for computer graphics, oRGB is a new color model based on opponent color theory. It works well for both HSV-style color selection and computational applications such as color transfer. oRGB also enables new applications such as a quantitative cool-to-warm metric, intuitive color manipulation and variations, and simple gamut mapping.

  • Image-Space Subsurface Scattering for Interactive Rendering of Deformable Translucent Objects

    Publication Year: 2009 , Page(s): 66 - 78
    Cited by:  Papers (4)
    Request Permissions | Click to expandAbstract | PDF file iconPDF (2350 KB) |  | HTML iconHTML  

    The authors present an algorithm for real-time realistic rendering of translucent materials such as marble, wax, and milk. Their method captures subsurface scattering effects while maintaining interactive frame rates. The main idea of this work is that it employs the dipole diffusion model with a splatting approach to evaluate the integral over the surface area for computing illumination due to mu...

    Immersive virtual reality (VR) has attracted the attention of many researchers and educators who predicted that VR would considerably affect how learning and teaching are conducted. The research presented here aims to investigate how an interactive immersive virtual learning environment affects conceptual learning, specifically learning of fractions in mathematics. A virtual environment (VE) desig... View full abstract»

    Science does not follow a linear path. Yet, persistence counts in research, and that's the case with virtual worlds. In the 1990s, many people perceived virtual worlds as a fad. Researchers and developers had to wait until innovations in networking, computer graphics, and haptics made the basic elements of VR inexpensive and ubiquitous. The Nintendo Wii is a great example of how technology has pro... View full abstract»
