Take advantage of the interchangeable nature of Iray's Interactive, Preview and Photoreal render modes through their easily changeable parameters; simply decide on the appropriate level of photorealism for each use and seamlessly switch between modes.
The interactive mode minimises render noise through the use of advanced optimisation algorithms that mimic photorealism. On top of this, the render mode effectively makes use of path space filtering, removing any noise from the final frame. This creates a seamless transition between the interactive mode and other render modes. There are different levels of interactvity available:
Using approximate ambient lighting effects with ray traced materials is the fastest interactive option available; enjoy real-time ray traced navigation and an experience that is far superior to the best OpenGL rendering available.
Ideal for quickly creating initial design stills and animations, the Interactive Direct mode combines direct lighting effects, ray traced ambient occlusions and diffused global illuminations.
Review design changes quickly and easily with the Interactive Preview mode which combines direct lighting and approximated global illumination models to provide a high quality render.
The photoreal mode in Iray brings real world materials and lighting behaviours to all integrated applications. This high-performance mode generates photorealistic imagery, full global illumination, cuastics and luminance distribution through progressive refinements for highest the quality final frame output. The photoreal rendering mode is ideal for the final stage of image production.
