Join Brian Bradley for an in-depth discussion in this video Understanding Final Gather, part of Up and Running with mental ray in 3ds Max.
…Irradiance mapping is a term that is probably most widely associated with the v…ray renderer, as it is the name of one of its primary global illumination engines.…It is also though a technology that is being used in mental ray for…the longest time.…Although, it is now here by the name Final Gather.…In fact, over recent years Final Gather has probably become, with the inclusion of…extra diffused bounce calculations, Mental Ray's most used GI engine.…In this video, we want to spend a bit of time running over the basics of…just how irradiance mapping works, simply because…understanding the basic principles of the technology can oftentimes go a long way…towards helping us make good use of the features and controls it offers.…Now, one thing we do need to know right from the start here is that…irradiance mapping is a view dependent global-illumination technique.…This means that the global-illumination solution is calculated or…created only from the rendering camera's point of view.…If we move the rendering camera, after we have calculated the irradiance mapping…
