The light-caching approach works efficiently with any lights - including skylight, self-illuminated objects, non-physical lights, photometric lights etc. Rays are only traced from the camera, as opposed to the photon map, which must process each light in the scene and usually requires separate setup for each light. The light map is a universal GI solution that can be used for both interior or exterior scenes, either directly or as a secondary bounce approximation when used with the irradiance map or the brute force GI method. Each of the bounces in the path stores the illumination from the rest of the path into a 3d structure, very similar to the photon map. The light map is built by tracing many many eye paths from the camera. It is very similar to photon mapping, but without many of its limitations. Light cache – Light caching is a technique for approximating the global illumination in a scene. Indirect illumination with motion-blurred moving objects is not entirely correct and may lead to noise (although in most cases this is not noticeable). The irradiance map requires additional memory. If low settings are used, flickering may occur when rendering animations.

Some details in indirect lighting can be lost or blurred due to the interpolation. The irradiance map can also be used to accelerate direct diffuse lighting from area light sources. The irradiance map can be saved and re-used to speed up calculations of different views for the same scene and of fly-through animations. The noise inherent to direct computation is greatly reduced. The irradiance map is very fast compared to direct computation, especially for scenes with large flat areas. The basic idea is to compute the indirect illumination only at some points in the scene and interpolate for the rest of the points. Irradiance map – Based on irradiance caching.

Tends to produce noise in the images, which can be avoided only by shooting a larger number of rays, thus slowing it even more. Indirect illumination in the case of motion-blurred moving objects is computed correctly.

When you are done with this course you will know how to bring a 3d model into Vray for Sketchup 2016 and Vray for Rhino 5, render it out, and touch it up in Photoshop to give your final image a professional finesse.V-Ray implements several approaches for computing indirect illumination with different trade-offs between quality and speed:īrute force – The simplest approach indirect illumination is computed independently for each shaded surface point by tracing a number of rays in different directions on the hemisphere above that point. Finally you will learn how bring your rendered image into Photoshop for post production, utilizing rendered channels, adding real world images, and compositing effects. Then, you will learn how to render out your model, including how to utilize render settings and how to tweak those settings to get your rendered image ready for post production. First you will learn how to set up your initial project, including bringing in a 3d model, setting up lights and cameras, and creating materials. 3d Rendering with Vray 3.2 for SketchUp and Rhinoģd Rendering with Vray 3.2 for SketchUp and Rhino : In this course, Jorge Barrero from HKS will show you how to create beautiful 3D renderings with Vray for SketchUp 2016 and Vray for Rhino 5.
