NVIDIA Iray: light matters

The NVIDIA` new Iray technology allows developers to avoid the mistakes when designing glass constructions. A physically correct rendering enables a user to create photorealistic images, accurately taking into account the sunlight and material interaction.

Why is it so important?
Here is a perfect example of London skyscraper, unofficially titled – Walkie-Talkie (got its title for non-standard cranked form, resembling the walkie-talkie). It`s the 37-storeyed glass building. The buildings` cranked surface made the skyscraper to accumulate some intolerable concentration of sunrays, reflecting them as multiplying glass. This resulted at fusing someones` Jaguar parked near-by and goods damage at the near-by stores.
NVIDIA analyzed the situation with skyscraper and came to the conclusion that, if the building had some bigger crank the tragedy would be much bigger. In such case the building could melt even lead! The NVIDIA experts are sure that the developers didn’t do it on purpose; they just had no proper instruments, to calculate the building interaction with the environment. Now it`s possible, by using the Iray technology.
This technology can be used in various activities:

  • Design;
  • Architecture;
  • Engineering;
  • Advertising and marketing.

The single process
Eearlier on, the modeling of reflected light required much time and customer got the models with selected view angles and specific lighting conditions now it`s possible to do interactive modeling with changeable sphere, taking into account weather conditions and the time of day. This resulted at the creation of 3D images comparable to photos, by their quality, and a significant decrease of working time, required for final scenes creation.
Working with Iray technology requires no deep knowledge. NVIDIA has included Iray support to a range of popular applications, used for 3D-content creation. The mode uses modern approximation algorithm, minimizing barriers and attaining maximum realism. Iray automatically distributes rendering load on several processors, including the ones at remote cluster.
