Advanced Settings for Image Rendering with OSPRay

Note: Please keep in mind that your CPU must have at least SSE 4.1 if you want to use OSPRay in pCon.planner.

You can actively render with OSPRay. You can change several settings during the rendering process without having to restart it. These settings are:

Stopping conditions
Output as HDRI image
Tone Mapping

These additional setting changes will restart the rendering process:

Camera Type
Ray Depth
Contribution Threshold

You can change these settings after the image rendering process is complete:

Background – type and settings
Output as HDRI image
Tone Mapping

Image Background and Lighting when Rendering with OSPRay

OSPRay uses the background settings from the real-time view. You can find these in the Environment dialog under the View tab. In the Environment dialog, set background panoramas, settings for ambient lighting, etc. have an effect on the plan view as well as in the photo-realistic images.

Setting

Background

Stopping Condition

Here you can adjust at which image quality the rendering process should be stopped. For Preview, Medium or High, the rendering process will automatically stop as soon as the given level of quality is reached.

If you set the level to Unlimited, the image rendering will continue running until you click the Stop button in the upper left corner of the Image dialog.

Ray Depth

Ray depth for path tracing. Refers to how often a single ray of light is reflected within the scene. It is recommended to keep the preset value.

Closed scenes with little illumination benefit from a high Ray Depth. An example would be the illumination of alcoves within a complex office layout.

Contribution Threshold

A low value prevents aliasing effects in strongly illuminated image areas. Low values also reduce the contrast within the image.

Transparent Background

Determine whether or not the background should be transparent.

Create HDR Image

The rendering will be displayed as an HDR Image (High Dynamic Range Image).

Tone Mapping

Select the method for the adjustment of the color range within an image for the display capacity of conventional monitors, so that the rendered result appears as natural as possible for the viewer.

Here you can select from Simple, Filmic, Drago and Reinhard. Filmic is the default method. Filmic, Drago and Reinhard compress the contrast range more in bright areas of the image than in darker sections. In comparison to Simple, these processes generate more dynamic images.

The method Simple uses a simple procedure to filter out all color values that are too bright for a conventional monitor.

Architectonic Camera

If this box is disabled, the default camera will be used. The image will be calculated in a real perspective. If you check the box for the architectonic camera, the perspective view will be straightened out so that all vertical edges in the plan are also displayed vertically in the rendering.

Shadow Plane

When this option is enabled, a transparent plane is placed on the zero level. This generates a realistic shadowing underneath individual 3D models.

This option can be used to create photo-realistic visualizations for free-standing products. The image background will contain the shadowing for the depicted object.

We recommend setting the Background to Transparent for this feature. By doing this, you can use and further process the generated product images in other image editing programs as well as integrate them into other scenes.
It is also advised to set the Tone Mapping to Simple.
Please keep in mind that the product model should be placed at the zero level in accordance with the World Coordinate System.

Advanced Reflections

When this box is checked, perspective-dependent surface reflections will be calculated.

Lines/Keep Lines

This setting means that during the photorealistic rendering of an image, not only are the spatial objects and surfaces considered, but the lines and 2D drawing primitives as well. These will be visible in the rendered image.

You could also input a Line Width Factor, which will be multiplied by the line width and will influence the width of the lines in the printing result.
