Multi-View Visibility Orderings for Real-Time Point-Sampled Rendering
نویسندگان
چکیده
Occlusion-compatible traversals and z-buffering are often regarded as the only choices for resolving visibility in the imageand point-based rendering community. These algorithms do either per-frame or per-pixel computations. This paper first discusses visibility orderings for point samples in general and then discusses orderings that are valid for multiple views. Then we present a novel, highly efficient, visibility algorithm for point-sampled models that has much smaller per-frame cost than previous approaches. We also discuss a high-performance, cache friendly implementation of this visibility method and present results. Finally, we speculate on possible hardware implementations.

Polyhedral Visual Hulls for Real-Time Rendering
We present new algorithms for creating and rendering visual hulls in real-time. Unlike voxel or sampled approaches, we compute an exact polyhedral representation for the visual hull directly from the silhouettes. This representation has a number of advantages: 1) it is a view-independent representation, 2) it is well-suited to rendering with graphics hardware, and 3) it can be computed very qui...
متن کاملStochastic visibility in point-sampled scenes
This work introduces a new statistical model of visibility in point-sampled scenes, such as those constructed from multiple lidar or depth-camera scans. A visibility density is defined along each optical ray, which gives the probability that a non-occluded scene-point exists at any particular location, with respect to a given camera. The new approach avoids any commitment to a surface-mesh, in ...
متن کاملReal-Time View Independent Rasterization for Multi-View Rendering
Existing graphics hardware parallelizes view generation poorly, placing many multi-view effects – such as soft shadows, defocus blur, and reflections – out of reach for real-time applications. We present emerging solutions that address this problem using a high density point set tailored per frame to the current multi-view configuration, coupled with relatively simple reconstruction kernels. Po...
متن کاملA graphics processing unit based method for dynamic real-time global illumination
Real-time realistic image synthesis for virtual environments has been one of the most actively researched areas in computer graphics for over a decade. Images that display physically correct illumination of an environment can be simulated by evaluating a multi-dimensional integral equation, called the rendering equation, over the surfaces of the environment. Many global illumination algorithms ...
متن کاملConservative From-Point Visibility
Visibility determination has been an important part of the computer graphics research for several decades. First studies of the visibility were hidden line removal algorithms, and later hidden surface removal algorithms. Today’s visibility determination is mainly concentrated on conservative, object level visibility determination techniques. Conservative methods are used to accelerate the rende...
