Plane Sampling for Light Paths from the Environment Map
نویسندگان
چکیده
We present a method to start light paths on an emitting environment map in the context of Monte Carlo global illumination with image-based lighting or physical sky models. With this technique we can efficiently render unbiased caustics from these kinds of lights, for example using bi-directional path tracing. Additionally it is now possible to use algorithms like multiple importance sampling, photon mapping and instant radiosity correctly with environment maps.

Sequential Monte Carlo Methods for Physically
The goal of global illumination is to generate photo-realistic images by taking into account all the light interactions in the scene. It does so by simulating light transport behaviors based on physical principles. The main challenge of global illumination is that simulating the complex light interreflections is very expensive. In this dissertation, a novel statistical framework for physically ...
متن کاملNavigation of a Mobile Robot Using Virtual Potential Field and Artificial Neural Network
Mobile robot navigation is one of the basic problems in robotics. In this paper, a new approach is proposed for autonomous mobile robot navigation in an unknown environment. The proposed approach is based on learning virtual parallel paths that propel the mobile robot toward the track using a multi-layer, feed-forward neural network. For training, a human operator navigates the mobile robot in ...
متن کاملReal-Time Perspective Optimal Shadow Maps
Shadow mapping is perhaps the most pervasive method for creating convincing shadows in computer graphics. However, because it is an image-space algorithm it must contend with aliasing issues caused by finite and discrete sampling. This exposition differs from previous work on shadow maps in that it pinpoints the one remaining degree of freedom in the shadow mapping process – the angle of the fi...
متن کاملRecursive MIS Computation for Streaming BDPT on the GPU
Bidirectional Path Tracing (BDPT) is a robust unbiased rendering algorithm that samples paths by connecting eye and light paths. By optimally combining different sampling strategies using Multiple Importance Sampling (MIS), BDPT efficiently renders scenes with complex light effects. However, BDPT does not map well on a streaming architecture such as the GPU; Stochastic path lengths lead to an u...
متن کاملPixel Cache Light Tracing
In this paper, we introduce Pixel Cache Light Tracing, which is a new low-noise combination of eye-path and light-path tracing. In the first pass, eye-path vertices are distributed from the observer and stored in a hit point map analogous to progressive photon mapping. In the second pass, photons are traced from the light source and projected to the image as well as gathered by the hit point ma...
