Stochastic Light Culling for VPLs on GGX Microsurfaces
نویسندگان
چکیده
Equal-time comparison. Stochastic light culling has a trade-off between the performance and quality, which is controlled by the user-specified parameter δ. Therefore, our ellipsoid-based approach can render higher-quality images than the sphere-based approach when comparing at the same computation time. Fig. 2 shows the equal-time comparison between the bounding sphere and our bounding ellipsoid for the Museum scene. As shown in this experimental result, we are also able to improve the quality using our bounding ellipsoid.

Rich-VPLs for Improving the Versatility of Many-Light Methods
Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality goals. However, they are very inefficient at representing glossy light transport. This is because a VPL on a glossy surface illuminates a small fraction of the scene only, and...
متن کاملIncremental Instant Radiosity for Real-Time Indirect Illumination
We present a method for rendering single-bounce indirect illumination in real time on currently available graphics hardware. The method is based on the instant radiosity algorithm, where virtual point lights (VPLs) are generated by casting rays from the primary light source. Hardware shadow maps are then employed for determining the indirect illumination from the VPLs. Our main contribution is ...
متن کاملReal-Time Global Illumination in Point Clouds
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 ligh...
متن کاملStochastic simulations of a multi-group compartmental model for Johne's disease on US dairy herds with test-based culling intervention.
Infection elimination may be an important goal of control programs. Only in stochastic infection models can true infection elimination be observed as a fadeout. The phenomena of fadeout and variable prevalence are important in understanding the transmission dynamics of infectious diseases and these phenomena are essential to evaluate the effectiveness of control measures. To investigate the sto...
متن کاملInstant Multiple Scattering for Interactive Rendering of Heterogeneous Participating Media
Rendering participating media with multiple scattering is costly and often even challenging for off-line methods. In this paper we present a novel method for efficiently rendering such effects that achieves interactive speed for dynamic scenes with both homogeneous and heterogeneous media. It is based on instant radiosity, which is typically used to approximate indirect illumination between sur...
