Real-Time Global Illumination in Point Clouds
نویسندگان
چکیده
In this paper we present a real-time global illumination approach for illuminating scenes containing huge point clouds. Our GI approach is based upon the distribution of Virtual Point Lights (VPLs) in the scene, which are then used for the indirect illumination of the scene geometry, using Imperfect Shadow Maps for visibility calculation of the VPLs. We are able to render multiple indirect light bounces at real-time rates, where each light bounce handles the transport of both the diffuse and the specular fraction of the reflected light.

A novel method for locating the local terrestrial laser scans in a global aerial point cloud
In addition to the heterogeneity of aerial and terrestrial views, the small scale terrestrial point clouds are hardly comparable with large scale and overhead aerial point clouds. A hierarchical method is proposed for automatic locating of terrestrial scans in aerial point cloud. The proposed method begins with detecting the candidate positions for the deployment of the terrestrial laser scanne...
متن کاملReal-time Realistic Illumination and Shading of Stratiform Clouds
Realistic rendering of clouds involves solving the complex interaction of light within the cloud and with its environment. Interactive methods achieve efficient cloud rendering by ignoring several lighting effects. However, these effects are visually important, and removing them strongly reduces realism. We present a novel approach for capturing the important effects of multiple anisotropic Mie...

Kontakt: [email protected], [email protected] Results We store the attributes of Q in that pixel and shade it afterwards using our Global Illumination framework. Our algorithm operates on local surface intervals of homogeneous curvature. We thus first create a Labeled Homogeneous Curvature Map, containing unique IDs for each homogeneously curved region per pixel. We assign each scene...
متن کاملReal-Time Global Illumination for Games using Topological Information
Indirect Illumination is a key element to achieve realistic rendering. Unfortunately, since computing this effect is costly, there are few methods that render it with real-time frame rates. In this paper we present a new method based on virtual point lights and topological information about the scene to render indirect illumination in real-time. Keywordsreal time rendering, global illumination,...
