Background and Reflection in Fotorealistic Rendering

Note: On our Youtube channel you will find a video on this topic

background_video

 

Use panoramic background images to give your renderings a more realistic look. In this video, we'll show you how to download panoramic images for free and add them to your design with just one click. Use the sliders to adjust the aperture angle and rotation until the background matches the selected perspective.

The dialog Environment can be found under the View tab in the group Render.

With this dialog, you can control the ambience of your drawing: Background and global lighting.

The settings from this dialog will be shown in real time and automatically saved with the drawing file.

The Set as Default button will save the settings from this dialog as default settings for new plans.

pcon.planner_Umgebung_1

Background

This is where you set a background color or select a skybox for your planning.

Assign a background color for the 2D displays as well as the orthographic and isometric projections.  

The Skybox is visible in all Render Modes. It is displayed in perspective and orthographic projections.

Skybox

Option

Background

Off

The background will be shown as the color set above.

Default

The Default Background (slightly cloudy sky) will be used.

Custom

A user-defined background will be used.

Click on the 3 dots on the right side (see image below). Then, select a background from your local file system.

pcon.planner_Umgebung_2

User-defined Background

For a custom background, load a spherical panorama with an aspect ratio of 1:2 into your plan. Please ensure that the resolution of the panoramic image is as high-quality as possible.

For the user-defined background, provide the following settings:

Rotation – Set the horizontal orientation of the panoramic background

Opening Angle – Set the height for the section of the image that you would like to see in the background. A smaller opening angle makes the background appear visually closer. A larger opening angle makes it appear more distant.

Note: Your background settings will automatically be used for rendering with OSPRay.

Ambient Light

Ambient Light evenly illuminates your plan. It has a positive effect on the quality of your renderings.

In real time view, Ambient Light operates in both the Shaded and Realistic render modes. It is also active in render styles that are based on these two render modes. In the illustration, you can see a scene set using the render mode Realistic.

Option

Background

Default

Enables pCon.planner’s default ambient lighting.

Custom

A user-defined image will be used for the lighting. The specific light color and mood will be used for the plan.

Click on the three dots to the right (see image below). Then, select a background image from your local file system.

We highly recommend using an HDRI image (High Dynamic Range Image) for the light source. Best would be a spherical panorama with an aspect ratio of 1:2. It is possible, however, to use other images.

pcon.planner_Umgebung_3

If needed, you can set the Rotation and Intensity of the Ambient Light.

Your settings for Ambient Light will automatically be used for rendering with OSPRay.

pcon.planner_Umgebung_4        

Images as Lighting Environments: Left side sunset, intensity 60%; Right side daylight, intensity: 100%

Sunlight

In addition to the Ambient Light, you can add sunlight if necessary. This is a light from a certain direction, which simulates the light and shadow conditions on a sunny day.

As sunlight, insert a Directional Light (Start tab, group Room Elements). Align this in your planning as desired.

Activate the Realtime Shadows option in the Properties Editor for the directional light source. We recommend activating the Realtime Shadows option only for rendering images. To sustain the optimal performance, please keep Realtime Shadows deactivated during the planning process.

Environment and Reflections

The behavior of reflecting surfaces - for example of mirrors - in the pCon.planner real-time view differs from the behavior of mirrors in the real world. There are five scenarios, depending on the settings used in the Environment dialog:

Skybox: Off, Lighting Environment: Default

The default Lighting Environment of pCon.planner is reflected.

pCon.planner_umgebung_reflexion_1

Skybox: Default or Custom, Lighting Environment: Default

The default Lighting Environment of pCon.planner is reflected.

 

pCon.planner_umgebung_reflexion_2

Skybox: Default or Custom, Lighting Environment: Custom and identical with Skybox

The user-defined Lighting Environment is reflected.

Note: If Lighting Environment and Skybox are identical, this can - in some cases - be used to get realistic reflections. However, the color of the light from the Lighting Environment can influence the atmosphere and the colors in the planning in an unwanted way.

 

pCon.planner_umgebung_reflexion_3

Skybox: Off, Lighting Environment: Custom

The user-defined Lighting Environment is reflected.

 

pCon.planner_umgebung_reflexion_4

Skybox: Default or Custom, Lighting Environment Custom and different from Skybox

The user-defined Lighting Environment is reflected. It does not match the Skybox: Reflexions and background are not compatible.

pCon.planner_umgebung_reflexion_5

Note: The objects in the planning are NOT mirrored in the real-time display in reflecting surfaces. Only the lighting environment is always mirrored.

Background and Reflection in Fotorealistic Rendering

Hints for creating photorealistic images with the Image dialog (Presentation tab):

Images created with the View setting behave as described in the previous section.

In photorealistic rendering, the objects in the planning process - furnishings, drawing elements, images, etc. - are correctly reflected in reflective surfaces.

Background images behave differently when it comes to reflection Read more in the chapter Photorealistic Images.
