AftabRad Revit Add-in -> Defining Radiance Views based on Revit Views

Here, there is a tutorial about the Radiance Views Panel that can help the users to modify the Radiance view parameters (such as view points, view directions, view horizontal and vertical sizes, etc.) of each selected Revit views and preview it in Radiance, before doing the final simulation.

Therefore, to do such Radiance views modification, we should do the following steps:

Press ExportToRadiance button in the AftabRad Add-in

1- Select, for example, Daylight Factor in the Type of Sky/Analysis

2- Press Rif Settings button to open the Rif Setting page to define

i. The 3D views that you want to include when export the model into Radiance. (Here, we will define on which views we want to do the export to Radiance.

ii. Image Quality, Model Detail and Light Variability

iii. Image Resolution

iv. Calculation Type (luminance/radiance or illuminance/irradiance)

v. Indirect Reflection (in this analysis it should be zero)

3- To create a good view that satisfy our expecatation regarding the view point, view direction, horizontal and vertical field (in degree) or width of the view, we can checked the Open Radiance View Panel checkbox.

4- Be sure that you checked the checkbox next to the Rif Settings button, and press the Do Export2Radiance button.

5- If you checked the Open Radiance View Panel checkbox, the Radiance View Panel will be opened.

In this page, we can change all different Radiance parameters of the selected view, and preview the image by pressing >> Preview >> button. As soon as we are satisfy with the image,

we can save that view parameters by pressing the Save button and then we can press Continue to continue the export to Radiane procedure.

6- After pressing the Continue button, the calculation process will be start. Here it is worth to metion that, since it does its calculation for hour in the selected period, it can take from a few minutes to few hours.

So, please prepare for a long calculation time.

7- Now, it is time to make the image based analysis. Therefore, the next step is to press the OpenAftabFC Button.

8- When the FalseColor Analysis page is opened, it is automatically opend the File Openning page.

Therefore, here we need to open an HDR file that, in this case, should be one of those that are created when the Daylight Factor view based calculation is finished.

9- In the FalseColor Analysis Page, we can measure the values of each point by clicking on the image, or find the average of an area by drawing a rectangular or circle.

In Daylight Factor Analysis, the Multiple No. (Multiplying Number) should be 1.

10- Moreover, in this page, we can make falsecolor images too.

For example, by changing the Scale value to 100, and under the Label drop down list, choose DF as the Label, by pressing the Do FalseColor button, we can create a falsecolor image.

11- To know more about different function of FalseColor Analysis Page, you can take a look at this pdf file or this link.
