This paper presents a system for rendering very large collections of randomly parameterized plants while generating manageable scene geometries for rendering A given botanical description of a plant is compiled into a hierarchical volume approxima tion This is then integrated into a multiresolution rendering system that uses adaptive volume re ne ment For objects that are close to the viewer ex...

High compression of plant geometry is an important aspect in fast realistic visualization of plants. Hierarchical structuring plant morphology is a key factor for real time plant rendering, especially when pedestrian views, including both close-ups and far views, are requested. We present here a new geometric simplification method, called Viewdependent Hierarchical Foliage Simplification (VHFS)...

BACKGROUND Current occupational and public health guidance does not distinguish between rendering plant workers and cullers/poultry workers in terms of infection risk in their respective roles during highly pathogenic avian influenza poultry outbreaks. We describe an operational approach to human health risk assessment decision making at a large rendering plant processing poultry carcasses stem...

Recent developments in rendering have provided very realistic images. However, these images rarely show organic objects. We believe that one of the main difficulties of rendering these objects realistically is the lack of reflectance and transmittance models oriented to organic materials. In this paper an algorithmic reflectance and transmittance model for plant tissue oriented to computer grap...


 The main aim of this article is to describe the conceptual basis and challenges project Volumetric Frictions. Frictions a queer virtual reality resulting from my will render ongoing PhD research (“Digital Speculation, Fictions. Volumetric/3D CGI within contemporary debate”) differently. To contextualize project, I start by addressing debates about role queer, practice queering, in academ...

L-Systems have been extensively utilized in plant modeling and music rendering. However, the music generated was not very pleasant as the grammars used are very simple. This paper describes a hybrid method that generates more complex grammars for L-Systems in a visual language framework for music rendering so that the musical sounds generated can be improved and fine-tuned. The method which use...

We present a simple and practical method for rendering leaves and other translucent parts of plants. In contrast to other translucent materials, plant leaves usually are thin, though highly textured. An adaptation of rendering methods for translucent materials in combination with a set of predefined textures allows us to represent plants realistically. A hardware-based approximation of the shad...

Light plays a vital role on the growth and development of plant. On the base of white light with high color rendering to the benefit of human survival and life, we proposed to improve "color rendering" of LED lighting for accelerating the growth of lettuce. Seven spectral LED lights were adopted to irradiate the lettuces under 150 μmol·m-2·s-1 for a 16 hd-1 photoperiod. The leaf area and number...
