Sinusoidal transform is separated into audio analysis and synthesis phases. Referring to the ideas of progressive refinement of geometry/image and scalable video, head related transfer function(HRTF) filtering is naturally integrated into a progressive resynthesis process and MPEG psychoacoustic model 1 is used to guide the selection of matching pairs before transmission/synthesis. The implementation of this scheme in a distributed virtual environment has quite a few advantages, including scalability,...

Sinusoidal transform is separated into audio analysis and synthesis phases.

In this paper, a novel hybrid multiresolution approach is proposed to efficiently render highly detailed objects based on the respective merits of point-based and polygon-based rendering. Both point and polygon are tightly integrated into the uniform structure of P-Quadtrees, which are constructed from geometry images.

In this paper, a novel hybrid multiresolution approach is proposed to efficiently render highly detailed objects based on the respective merits of point-based and polygon-based rendering. Both point and polygon are tightly integrated into the uniform structure of P-Quadtrees, which are constructed from geometry images. While traversing the P-Quadtrees in rendering, the part of surface that faces the viewer can be rendered by coarser quad mesh to reduce the numbers of rendering primitives. The shading details can be enhanced by hardware accelerated normal mapping. The view-dependent LOD (level of detail) selects the finer hierarchy on silhouette, which is rendered by points. The rendering efficiency of large-scale model is greatly improved while the visual effect at both the surfaces and the silhouette is guaranteed.

根据点和多边形在表示和绘制物体上各自不同的特点,提出了一种有效绘制细节高度复杂物体的多分辨率方法.3D表面被映射到参数平面,经规则采样成为几何图像,P-Quadtrees是基于几何图像建立的四叉树多分辨率层次结构.通过对四叉树的遍历,面向视点的表面用较大多边形面片绘制,光照细节通过法向映射完成;轮廓部分通过视点相关的LOD(level of detail)控制进行细化,使用点来绘制物体复杂精细的轮廓.通过此方法,细节复杂模型的绘制不仅可以被硬件加速,而且无论在表面还是在轮廓部分都能获得很好的视觉效果.

This paper presents a novel approach for representing 3D point cloud surfaces using geometry images 3D points are converted to images based on spherical polar coordinates, and point cloud surface information such as location, normal and color is stored in two dimensional images To create geometry image of point cloud surfaces, we first determine the center of the polar coordinates and convert the Cartesian coordinates [x,y,z] to polar ones [r,φ,θ] , with the coordinate [φ,θ] encoded as the location and r as the gray value in the image To represent/reconstruct point cloud surfaces with high complexity, we propose using multi layered images From the point cloud surfaces, multi layered geometry images are created which can represent the original models very accurately This approach can be used in the compression, editing, simplification, model retrieval and progressive transmission of point cloud surfaces
