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.

Use the Custom level to set an own variance value as stopping condition for the rendering.

Variance Threshold

Available for Stopping Condition: Custom. Statistic value of the remaining noise within the image. The smaller the value the higher the image quality. The value runs towards 0.

We recommend the value 1.5.

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.

Licht Calculation

Accelerates image rendering by defining the number of light sources taken into account for each render pass.

Levels:

•Truncated: Uses just one light source per render pass. Very quick setting, produces hardly any difference to higher settings for simple lighting scenarios.

•Simple: Sufficient for most lighting scenarios.

•Medium: Default setting. Is used for medium complex lighting scenarios.

•High: Only needed for complex lighting scenarios.

•Maximum: Uses all light sources in the scene for every render pass. Slowest setting, only recommended for specifically complex lighting scenarios.

Note: The results depend on the lighting situation and the overall complexity of the drawing. Light Calculation will not have an effect if there are no additional light sources used in the drawing besides the Ambient Light.

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.

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.

Use Fixed Line Color

Available when Keep Lines is activated. Set a homogeneous color value for all lines in the image.
