Velux Loft Blinds Visualisation Case Study

The Brief:

To create a photorealistic 3D interior visualisation of a loft space fitted with Velux windows and Loft Blinds. A flatscreen TV was required to display a promotional video. The Interior needed to be lit from the outside, with the blackout Loft Blinds evidently blocking the light from entering the room.

The Solution:

The first step was to create an accurate 3D CAD model of the scene. This included the room, Velux windows, Loft Blinds, flat screen TV, power cable and the plug socket. Reference images were utilised to assist the reverse engineering 3D modelling process.

Once the modelling process was complete, a sample ‘clay’ render (a render without materials) was sent over to the client to approve the geometry, perspective and camera angle.

With the geometry and camera angle approved, the detailed UV texture maps were created from the reference photos. The UV texture maps give the CAD geometry physically accurate surface finishes, materials and colour. The lighting was refined using accurate physical sky settings. This feature allows us to define the exact longitude/ latitude, date and time of day, based on data imported from a Google Earth TM KMZ/ KML file. Data variables include the Suns temperature (5777ºK default), planet reflectance, turbidity coefficient, aerosol properties and the ozone gas properties.

A draft render was sent to the client for final approval with regards to the materials and composition before the high resolution render was set to run.

At this stage, a few minor tweaks to the composition were implemented and the 3D render scene was processed in high quality.

Light retouch and post production techniques were applied to further enhance the quality, lighting and colour grading of the image before the final 3D visualisation was sent over to the client.

The Result:

Our client,Hayden Digital, was delighted with the final 3D interior visualisation. The final image was used on an authorised Velux distributor’s website to showcase the Loft Blinds, play a promotional video on the TV screen and select Genuine Velux Loft Blinds via an (interactive) product model sector.

This project is a great example of how photorealistic images can be cost effectively produced on a very quick turn around to achieve high impact results.
