This document provides an introduction to volume rendering techniques. It discusses stochastic techniques for rendering participating media with constant refractive index. It also covers the radiance transfer equation and techniques for sampling distance through media, including ray marching, Woodcock tracking, and acceleration structures. Methods for importance sampling, density estimation using photon mapping and beams, and a unified framework are also summarized.
This document discusses Markov chain Monte Carlo (MCMC) based rendering techniques. It introduces Metropolis light transport (MLT) as the original MCMC rendering technique. It then summarizes several advanced MCMC techniques that build upon MLT, including Primary sample space MLT (PSSMLT), Multiplexed MLT, Manifold exploration (ME), Energy redistribution path tracing (ERPT), Population Monte Carlo ERPT, and Replica exchange light transport. These techniques aim to more efficiently sample light paths that follow the distribution of radiative energy in complex scenes.
The document summarizes furniture designed for Indian classrooms with input from experienced Japanese designers. It focuses on comfort, safety, and durability. Key features include rounded edges for safety, imported plywood and laminate tops for easy cleaning, and Japanese rivets to join seat and back frames. The furniture undergoes rigorous product testing and is manufactured in a fully integrated facility.
Artificial Bee Colony (ABC) algorithm is a Nature
Inspired Algorithm (NIA) which based on intelligent food
foraging behaviour of honey bee swarm. This paper introduces
a local search strategy that enhances exploration competence
of ABC and avoids the problem of stagnation. The proposed
strategy introduces two new local search phases in original
ABC. One just after onlooker bee phase and one after scout
bee phase. The newly introduced phases are inspired by
modified Golden Section Search (GSS) strategy. The proposed
strategy named as new local search strategy in ABC
(NLSSABC). The proposed NLSSABC algorithm applied over
thirteen standard benchmark functions in order to prove its
efficiency.
Lightmetrica is a renderer designed for research purposes that is based on Veach's path formulation. It is extensible but moderately fast and unit tested. While it supports implementation of various techniques, it is missing some must-have features for typical rendering like environment lighting, filtering, advanced importance sampling, GPU implementation and volume rendering. The document discusses using bidirectional path tracing for rendering and lessons learned around prioritization and overreaching on implementations.

[2016 GDC] Multiplatform GPU Ray-Tracing Solutions With FireRender and FireRaysTakahiro Harada
The document discusses FireRender and FireRays, two GPU-accelerated ray tracing solutions. FireRender is a physically based rendering library that performs path tracing on the GPU using OpenCL. It provides features like cameras, lights, materials and multi-GPU support. FireRays is a ray intersection library for developers to integrate into their renderers. Examples are provided showing FireRender's API and capabilities like layered shaders. Performance benchmarks show a 5 second render time on dual Radeon Pro Duo GPUs.
