NX 11 Rendering - Iray+ Depth of Field


Now it is easier than ever to imagine your products visually. The new Lightworks Iray+ rendering engine in NX 11 delivers progressive ray tracing in a fully integrated environment with Ray Traced Studio. Not only is it easier to use, but you get high quality, photorealistic rendering. More accurate looking images help you make design decisions about aesthetics, function, and materials of a product early on, when the cost of change is much lower.


If you missed the introduction to NX 11 Rendering with Iray+, I highly recommend you go back and check that out. It will help you to understand the UI, the basic workflow to use, and the results you can achieve with the new Ray Traced Studio.


Today we will be looking at an effect you can use in NX 11 called Depth of Field. The term Depth of Field originates from photography and film, and it is the distance between the nearest and furthest objects in a scene that appear acceptably sharp and in focus. You can use Depth of Field to highlight particular features of a product. The effect makes images appear realistic like photographs, so you can create attractive imagery for use in marketing collateral such as magazine spreads, brochures, blogs, and advertisements.

Start in Ray Traced Studio. In the example shown in the video below, there is a part to which materials have already been applied.  Go to the Part Navigator and open up the Cameras folder. Patti captured a camera already with the Capture command, so we can open that from this folder. However, you can create your own capture to accomplish the same result.


With the capture open now in the Edit Camera dialog, it is possible to adjust the settings to achieve the desired Depth of Field effect. Pay attention to the distance between the camera and the target (listed under Camera options).  We are going to change the focal plane to be a bit closer than the current setting of 90 mm.

Check the Depth of Field box to turn on this effect. The Focal Distance is set to 80 mm, which is good for our purposes. Aperture follows what a camera’s aperture settings would do.  There is a dropdown menu of choices, so select a middle Aperture setting to start.

You can check to see how the changes you make will look using the Ray Traced Studio window to display the rendering. If you want to make adjustments, go back to change the Aperture setting for Depth of Field in the Edit Camera dialog. A low aperture setting creates a dramatic effect for an image that is primarily out of focus. Conversely, a high aperture setting creates a subtle effect for an image that is mostly in focus.

The change takes effect immediately, it is dynamic, and is completely within your control to adjust. Watch the NX Quick Tips video below to see NX Product Manager for Rendering, Patti Longwinter, demonstrate these steps.
