Raytracing calculation: Standard mode parameters

Kurt Bieri

The preparations for a visualization with the "Raytracing calculation" take in the same steps as those for a standard light calculation in ReluxDesktop.

1. Create a new project or add a new scene to your current project

2. Develop the layout of the room with furniture and wall materials, for example

3. For artificial light calculations: select and position the luminaires of your choice and for daylight calculations: 

    select and position at least one window or a skylight.

Calculation manager (Standard mode)

Once the layout of the scene has been completed, you can go further and open the calculation manager. 

Further inputs are required here, in the same way as for the standard light calculations. 

The calculation manager incorporates a switch box to activate the Radiance parameters. 

Let us first cover the standard settings, starting with the type of calculation:

Next, you’ll find the settings for the daylight calculations with the different sky conditions, together with the date and true local time. 

The time is converted and also shown as so-called "true solar time (TST)" using the date and the longitude entered in "Project - Location". 

This essentially determines the position of the sun and therefore the luminance distribution of the sky. 

If required, you can set the switch button "with sun" to calculate the effect of direct sunlight as well.

In the standard mode you can also set the image quality as well the number of "Inter-reflections"

The best possible quality of renderings is achieved with "high".

In the Expert mode, a lot more settings are additionally available.
